For those of you wondering who this "Lars" guy is, I'm the Astral Codex Ten reader who reviewed Henry George's Progress & Poverty for the book review contest. Henry George is the founder of an economic philosophy known as Georgism which is principally concerned with the deprivations caused by unchecked rentiers. George is famous for promoting two specific policies, the Land Value Tax (LVT) and the Citizen's Dividend (what we would now call a Universal Basic Income).

In real life you can't accurately assess land value separately from improvements, so even if LVT would work in theory, it doesn't work in practice Today we'll start with point 1, and subsequent articles posted in the next two days will address points 2 and 3. I'll probably write further articles on the subject, but I make no presumptions about whether I'll have worn out my welcome on Astral Codex Ten by then. If you haven't read the Book Review yet, I've posted a brief recap of the relevant concepts below. Otherwise, feel free to skip directly to the subsequent section. 0. A Brief Recap Georgism is a school of political economy that is really upset about, among other things, the Rent Being Too Damn High. It seeks to liberate labor and capital alike from those who gatekeep access to scarce "non-produced assets," such as land and natural resources, while still affirming the virtues of hard work and free enterprise. George uses the term "Land" to mean not just regular land, but everything that is external to human beings and the things they produce–nature itself, really. Georgism's chief insight is to move economic thinking from a two-factor model (Labor and Capital) to a three-factor model (Land, Labor, and Capital). It's chief (but not only) policy prescription is the Land Value Tax (LVT), which taxes real estate at as close to 100% of its "land rent" as possible (the amount of rent due to the land alone apart from "improvements" such as buildings). In actual practice, most Georgists seem to think 85% is a reasonable figure to target. Let's carefully unpack what those terms means. "Land value" refers to the full market value of a property, excluding all of its improvements, such as buildings. This is the portion of a property's value arising solely from its location and natural attributes (agricultural fertility, endowment of stuff like water, minerals, etc.). "Land rent" (AKA "ground rent") refers to the recurring rental income a property is capable of generating from the market because of its land value. It is Land Rent which Land Value Tax is intended to capture. You can think of it as a Location or Site Value Tax if that's more helpful. It's not a tax on the full market purchase price of a property, nor is it a fixed amount of tax per acre of land, but rather a tax proportional to the market value of the land alone (or better yet, the land rent). When assessed correctly, as LVT approaches 100% the market selling price of the land itself will approach zero. Don't let the "100%" confuse you, either. If a piece of land costs $10,000 to buy, and is leased for $500/year, then an LVT that captures 100% of the land rent is $500/year, which works out to a 5% annual tax of the land value. LVT should not be confused with a property tax. Property taxes consider land plus improvements (typically buildings). An LVT considers land value alone. Georgists assert that if we sufficiently tax land in this manner, we'll not only end the housing crisis but also fix a bunch of misaligned incentives that cause poverty to persist alongside economic progress, while raising a bunch of revenue that can lower or even eliminate other less efficient taxes, such as sales and income taxes. This is because virtually all economists agree that LVT has zero "deadweight loss"–a fancy word for a drag on the economy that makes certain activities no longer profitable. Other taxes with no deadweight loss include Pigouvian taxes on bad things, like congestion and pollution. But won't landlords just raise the rent to make up for the LVT, passing the burden of the tax on to the tenants? Georgists say no, because land is special in that it is scarce and nobody can make any more of it. Indeed, LVT is a rare form of taxation that actually boosts the economy, because it discourages rent-seeking and speculation. Some Georgists even go so far as to say that LVT can raise enough revenue to replace all other less efficient taxes, becoming the so-called "Single Tax," but this is not a universally held position among modern Georgists. To be clear, proponents of the "Single Tax" believe that LVT is sufficient for all public purposes and that no other taxes (such as income tax, capital taxes, and tariffs) are necessary for revenue generation, although they still might support carbon taxes or "sin taxes" on things they want to discourage. Georgism doesn't begin and end with the LVT, however, and the movement isn't solely concerned with real estate and tax revenue. Henry George was an early proponent of what we now call "Universal Basic Income," or as he called it, the "Citizen's Dividend" (funded by LVT, naturally). But even if you threw every penny of LVT revenue into the sea, the anti-sprawl effects of the policy are appealing enough by themselves to earn the endorsement of YIMBY's and urbanists like Strong Towns. If you take Georgism to its natural conclusions, you might start to question government-enforced monopolies over other kinds of "Land," such as electromagnetic spectrum, water and mineral rights, and orbital real estate for satellites, not to mention the deadweight loss created by intellectual property gatekeepers over, say, research papers. And if you have my day job as an analyst for the video games industry, one day you'll find yourself applying the observed 30-year history of housing crises in MMO's to virtual real estate sales in leading blockchain games. Some people come to Georgism because of their aversion to income and capital taxes, some want to use LVT to fund generous social programs, some are motivated by the beneficial environmental effects, and some just think the Rent is Too Damn High. No matter where you come from on the political compass, there's probably a way to mix up a club soda and Georgism that's right for you. 1. Is Land Really a Big Deal? Paul Krugman speaks for many mainstream economists when he admits that Georgist analysis is sound, but he insists that it's a moot point because land just isn't important anymore in the modern economy: Believe it or not, urban economics models actually do suggest that Georgist taxation would be the right approach at least to finance city growth. But I would just say: I don't think you can raise nearly enough money to run a modern welfare state by taxing land. It's just not a big enough thing. By George, if land just isn't a big deal, then LVT can't raise much money, the problems of speculative landownership are vastly overstated, and you can stop reading this article. The main tension between Georgists on the one hand, and Marxists and Neoclassicals on the other, is that the latter two significantly downplay land, centering the whole discussion instead on labor and capital. For Georgists, land is the key to understanding the whole economy. Krugman's main complaint is that LVT can't raise enough money, which is a response to the "Single Tax" movement in particular. In George's time, it was popular to advocate for a 100% Land Value Tax and the elimination of all other taxes. Keep in mind that in George's time, there was no federal income tax, and state and federal spending was much lower, so whether LVT could raise enough money wasn't nearly as controversial as it is today. But even if it turns out that a modern-day "Single Tax" isn't enough to cover the federal budget, Krugman misses the point. The purpose of LVT is not just to raise revenue, but to end speculation, rent-seeking, unaffordable housing, and wasteful, environmentally damaging sprawl. LVT is worth doing for those good effects alone. The revenue it generates doesn't need to fund literally every penny of government spending to still be a win, which is why Georgist economist Terrence Dwyer calls LVT "better than neutral." Liberal Krugman and conservative Milton Friedman both seem to agree that LVT has no deadweight loss, which means LVT, unlike income and capital taxes, doesn't create a drag on productivity. This means that if we can raise enough money from LVT, we can reduce at least some inefficient taxes, such as those on labor, while keeping government spending the same. Not only could this be popular politically, it would also boost the economy. Those are the claims Georgists make, at least. Let's see if they're true. Here are a few testable hypotheses that capture different aspects of land being a "really big deal": Most of the value of urban real estate is land

Almy (2014) - Valuation and Assessment of Immovable Property Not to mention Fundamentals of Mass Appraisal, a literal textbook published by the IAAO, written by Gloudemans and Almy in 2011. I've only scratched the surface here. There are a whole lot more methodology papers out there, and this is just a sample of the ones I happened to come across. They seem to fall into either "hands-off" or "hands-on" approaches, depending on how much direct human judgment you want to bake into the system. So, can we accurately assess land and improvements separately? I think it's quite plausible but not a slam dunk. That said, if the objection is, "valuing land separately from improvements is fundamentally impossible, and we can never get better at it, so we shouldn't try," I think that's plainly ruled out. We clearly have a variety of methods at our disposal that seem reasonably accurate. Each of them has particular strengths and weaknesses, and each directly addresses shortcomings of prior methods. All of this implies that this is something we can continue to improve at. The big questions are whether we've already arrived at "good enough" and how tight our error tolerances need to be. And the operative phrase very much is "good enough." I don't know of anywhere in the world that currently has a 100% LVT policy, let alone an 85% LVT. The lower your LVT, the greater your margin of error becomes for not taxing more than the true land value. I know plenty of Georgists who would be ecstatic if they could get a 75% LVT, or even a 50% LVT, implemented in their area. Now, just because these assessment methods are available doesn't mean they're actually being used. Not everyone has Ted Gwartney as their assessor. Plenty of counties in my local area exclusively use the cost approach and will even apply a blanket "neighborhood factor" multiplier to up-assess swiftly appreciating areas. However, they apply that multiplier to the buildings rather than the land, which feels exactly backwards. The assessor hasn't raised the value of my land in years, while the assessed value of my house (which I am eminently qualified to tell you is an ever-degrading money pit) somehow continues to go up. Good assessment depends on having well trained staff, up-to-date methodology, and access to high quality market transaction data. I'm convinced, based on these papers and the IAAO's surveys, that assessment doesn't require a huge army of assessors poring over every aspect of citizens' properties. Furthermore, plenty of places already have property tax systems in place and are already paying the full cost of property assessments and property tax collection. Many of the methods described above seem capable of reducing property assessment costs by focusing on the land first and foremost and letting the building's value fall out as a residual, as Ted Gwartney insists. The cost also seems like something that, done properly, is only going to come down over time as fewer assessors are required. Another option is to keep staff sizes the same but use the emerging productivity gains to increase the frequency and quality of assessments. It also seems clear to me that Land Value Taxation is not more invasive and expensive than income and sales tax when you factor in the cost of compliance (not to mention the deadweight loss imposed on the economy). Countries that have implemented Land Value Taxes, such as Denmark, are already seeing some of the claims of Georgism borne out, as we discussed in Part II. This suggests to me that modern methods are probably "good enough," so long as assessors are well trained, abiding by current best practices, and able to access good market data. Given that Astral Codex Ten is a blog where ideas as lofty as full brain uploading, superhuman AI, and biological immortality are frequently discussed in earnest, it doesn't seem outlandish to suggest that human beings can probably use math and science to get better at estimating the market value of land relative to buildings. Conclusion By George, Unimproved Land Value can (probably) be accurately assessed. 6. Conclusions & Next Steps This concludes my three part series on the most common objections to Georgism. By George, the evidence has convinced me of three things: ✅ Land is a really big deal ✅ Land Value Tax cannot be passed on to tenants ✅ Unimproved Land Value can (probably) be accurately assessed I humbly submit that the case for Georgism survives a summary dismissal and can move on to a trial of the particulars. So where do we go from here? In the course of writing this series, I found a few subjects that someone should just go ahead and test already. Obviously, this would require research funding and smart people willing to do the work (hey, a guy can dream). These subjects are: 6.1. Assessment methods A lot of the methodology papers I read test one or two methods at a time in a particular case study. What I couldn't find was a study that tests every major mass appraisal method in one big cross comparison study, all in the same physical location using the same dataset. If we had this, we could get a better sense of their strengths and weaknesses without wondering what differences are due simply to one study being in Germany and the other in the Philippines. It seems the necessary ingredients are: An ideal test location with excellent property records and (ideally) a history of quality land value assessment and/or Land Value Tax

They give their resolution source as this California government website, which says there have been fewer fires this year, 8800 vs. 9600. It’s been updated pretty recently, and this isn’t California’s fire season, so there’s no way there will be another 800 fires in the next four days. As far as I can tell, this is free money - though probably after Astral Codex Ten mentions this question, people will notice and correct it pretty quickly.

I think I have a good reputation of paying for things I say I am going to pay for, see for example last year’s ACX Grants. Manifold Markets is a company that runs a prediction market website and is generally interested in unusual market structures solving social problems. We’re co-sponsoring this impact market in order to test impact markets as a charitable funding mechanism.

Tales of Icarus flying too close to the sun, where readers revel in schadenfreude, e.g., When Genius Failed. With The Laws of Trading, Agustin Lebron has written something different: part love letter to trading, part philosophical treatise on epistemology and modeling the world around us, and part guide to applied decision-making. Lebron’s Laws are Laws of the Jungle, not Laws of Nature. He views financial markets as the most competitive Darwinian environment on Earth, where participants must adapt or die. According to Lebron, the book is for people working in finance and trading, as well as anyone in the business of making rational decisions. This explicitly rationalist bent is similar to Julia Galef’s The Scout Mindset or Annie Duke’s Thinking in Bets. Where The Laws of Trading sets itself apart is with the best description of financial market dynamics that I’ve ever seen while diving deep into philosophical concepts. Why trust Lebron? He is an engineer, worked as a quantitative trader and researcher at Jane Street, and has a deep understanding of trading. He has what Taleb would describe as skin in the game. You and I may read Astral Codex Ten in our spare time, post on LessWrong, and navel gaze about our epistemic certainty, but at the end of the day most of us are pursuing rationality for fun, as a hobby. Traders like Lebron pursue rationality as a profession: Their livelihood depends on having a better model of the world than their competition. There are lessons to learn from them that apply to our daily lives. 1: Motivation Know why you are doing a trade before you trade. “What is trading about? Fundamentally, it’s about the relationship between you and the rest of the world.” Right now, you’re making a trade. You’re trading your time to read this book review. You have a cost: you could be spending time with your loved ones, exercising, working, sleeping. You might be hoping to learn something, to take away lessons that you can apply to your life, or simply to entertain yourself. Here, off the bat, are two key insights: We are all making trades, all of the time.

The Rationalist revival has put wind into the sails of start-ups like Manifold Markets, which was initially funded by a grant program run by Astral Codex Ten, a Rationalist blog that has promoted prediction markets. (It also received $1 million from the FTX Future Fund, the philanthropic arm of the bankrupt crypto exchange whose founder, Sam Bankman-Fried, is a fan of prediction markets.)
I think a natural reading of this sentence is that Astral Codex Ten received $1 million from the FTX Future Fund. Some people who read the article said they understood it this way and thought I took FTX money. I didn’t. The article meant to say that Manifold did.

How many residents will live in Prospera, a new special economic zone in Honduras, on Jan 1, 2026? Answer: 600 (80% confidence interval 100-2,000) This seems like a good guess (except that my confidence interval would have included zero because there’s a 20%+ chance that it gets shut down). So overall its forecasts seem pretty impressive. But I was concerned by its reasoning even in some of the questions it got “right”. For example, the Nikki Haley question tried to get a base rate by asking what percent of elections Haley had won before, and found she had won 71% of them - these were mostly elections for South Carolina governor. You can see what the AI is trying to do - but it’s not going to work. Then it got confused and read a lot of news stories about how she’s currently losing the 2024 presidential election, and seemed to think they were about 2028. So either the AI only got a reasonable probability by coincidence, or it was testing many different strategies, throwing out the useless ones, and updating only on the useful ones, in a way that was kind of opaque to the casual reader. Still, if the company says it beats most human forecasters, this doesn’t seem totally impossible based on what I’ve seen. And that would be exciting! An AI that can generate probabilistic forecasts for any question seems like in some way a culmination of the rationalist project. And if you can make something like this work, it doesn’t sound too outlandish that you could apply the same AI to conditional forecasts, or to questions about the past and present (eg whether COVID was a lab leak). I would be most excited if at some point this graduated from its geopolitical focus and was able to answer questions on any topic (eg “what is the chance that Astral Codex Ten gains paid subscribers this year?”), maybe if the questioner gives it links or feeds it some of the appropriate information.

Vitalik On AI Prediction Markets Vitalik Buterin, Ethereum-founder-turned-cryptocurrency-public-intellectual, has a blog post on The Promise And Challenge Of Crypto + AI Applications. One of them is a prediction market. He writes: Prediction markets have been a holy grail of epistemics technology for a long time; I was excited about using prediction markets as an input for governance ("futarchy") back in 2014, and played around with them extensively in the last election as well as more recently. But so far prediction markets have not taken off too much in practice, and there is a series of commonly given reasons why: the largest participants are often irrational, people with the right knowledge are not willing to take the time and bet unless a lot of money is involved, markets are often thin, etc. One response to this is to point to ongoing UX improvements in Polymarket or other new prediction markets, and hope that they will succeed where previous iterations have failed. After all, the story goes, people are willing to bet tens of billions on sports, so why wouldn't people throw in enough money betting on US elections or LK99 that it starts to make sense for the serious players to start coming in? But this argument must contend with the fact that, well, previous iterations have failed to get to this level of scale (at least compared to their proponents' dreams), and so it seems like you need something new to make prediction markets succeed. And so a different response is to point to one specific feature of prediction market ecosystems that we can expect to see in the 2020s that we did not see in the 2010s: the possibility of ubiquitous participation by AIs. AIs are willing to work for less than $1 per hour, and have the knowledge of an encyclopedia - and if that's not enough, they can even be integrated with real-time web search capability. If you make a market, and put up a liquidity subsidy of $50, humans will not care enough to bid, but thousands of AIs will easily swarm all over the question and make the best guess they can. The incentive to do a good job on any one question may be tiny, but the incentive to make an AI that makes good predictions in general may be in the millions. Note that potentially, you don't even need the humans to adjudicate most questions: you can use a multi-round dispute system similar to Augur or Kleros, where AIs would also be the ones participating in earlier rounds. Humans would only need to respond in those few cases where a series of escalations have taken place and large amounts of money have been committed by both sides. This is a powerful primitive, because once a "prediction market" can be made to work on such a microscopic scale, you can reuse the "prediction market" primitive for many other kinds of questions: Is this social media post acceptable under [terms of use]?

Does this beat a centralized AI predictor? That depends whether you trust the centralized AI predictor or not! Remember, the biggest advantage of prediction markets isn’t necessarily accuracy, it’s trust and canonicity.

The Astral Codex Ten (ACX) Commentariat is defined as the 24,485 individuals other than Scott who have contributed to the corpus of work of Scott’s blog posts, chiefly by leaving comments at the bottom of those posts. It is well understood (by the Commentariat themselves) that they are the best comments section anywhere on the internet, and have been for some time. This review takes it as a given that the ACX Commentariat outclasses all of its pale imitators across the web, so I won’t compare the ACX Commentariat to e.g. reddit. The real question is whether our glory days are behind us – specifically whether the ACX Commentariat of today has lost its edge compared to the SSC Commentariat of pre-2021.
Complexity of thought – Perhaps the most important feature distinguishing the ACX Commentariat from other, lesser, blogs is that some really smart people comment here and give novel and well-nuanced takes on a topic. If this ever disappeared it would not matter about any of the other three features, because the Commentariat would effectively be dead anyway. To me, these broad categories represent the unique and positive features of the SSC/ACX Commentariat, and the extent to which they are present is a reasonable indicator of comment section quality, especially if they are all present at the same timepoint and that timepoint happens to line up with peak engagement in 2016 (this is foreshadowing). To generate data on the ACX Commentariat, I scraped the comments section of every post Scott has made since 2013. The Old Ones whisper of a blog that existed before even Slate Star Codex, but since I’m not 100% certain we’re encouraged to talk about the older blog (and nobody dates the golden era of Scott’s writing to pre-2013 anyway) I kept my scraping to just the two websites we’re definitely allowed to talk about; Slate Star Codex (SSC) and Astral Codex Ten (ACX). The main points of failure with my scraping were Subscriber-only threads (which my algorithm virtuously refused to read as it wasn’t a subscriber) and battling with the Substack UI to get all the comments to load for me simultaneously on larger threads. Nevertheless, between my incompetent code and the jaunty Substack UI I only dropped a few comments on even very long threads, so I figured the data scrape would be adequate for the use-case I had for it. I then used a bunch more janky code (some written by me, some written by ChatGPT) to try and quantify the levels of depth, freedom, politeness and complexity of each comment. I captured 2460 individual posts, and approximately 1.8m comments. Of the 24,486 unique comment authors, around 40% have made only one comment to the blog. The most prolific poster is the irrepressible Deiseach, at 20,685 contributions. Deiseach is also the only commentor to have made a comment on both the first post in my sample and the last, so has been with the blog a very long time! Only one other commentor has made more contributions than Scott (11,249), and this is John Schilling (11,607). The quality of data on individual users is not great for the ACX era (Substack seems to record missing author data in a few different ways, and sometimes swallow data for no reason) but I’m happy to give the rank ordering of anyone else who cares to know their specific level of clout in this niche community - I myself am the 799th most prolific contributor to the comments section (225 comments). I’m also delighted to share my raw data with anyone interested – the summary statistics per post are here. The scraped comments themselves are about 2Gb so I don’t know where I can host them but if anyone has any ideas (and Scott doesn’t mind) I’ll share them too. I know that some of the post titles seem to have turned into hieroglyphics, but as far as I can tell it is cosmetic only and won’t affect any of the actual data – it is a symptom of a cool hidden feature of Microsoft Excel where it open UTF-8 encoded CSVs in a way that garbles special characters for no particular reason. Considering each of these factors in turn: Depth of engagement with a topic
A couple of years ago Scott asked, Why Do I Suck?. This was a largely tongue-in-cheek springboard to discuss a substantive criticism he regularly received - that his earlier writing was better than his writing now. How far back do we need to go before his writing was ‘good’? Accounts seemed to differ; Scott said that the feedback he got was of two sorts:

(technically, you just know that Astral Codex Ten says there’s a book containing the sentence “there were over a hundred fifty eyewitnesses”.)
Then it returned to its normal position, and the previously drenched crowd noticed they were miraculously dry. …then almost every testimonial contains some elements of the consensus story, in approximately the correct order. The case for self-contradiction is that very few testimonials contain all six elements: most are a random subset of those claims. Also, nobody can agree on which colors were involved in (4), or in which order. A believer might argue that if you encounter six different miracles in close succession, they all sort of blend together and you might forget one or two in your accounting. Or you might turn to your friend and ask what they think, and while you’re not looking you miss part of what’s going on. A skeptic might argue that if the sun falls to earth and appears seconds away from crushing you and everyone around you is screaming because they think it’s the end of the world, approximately 100% of people should mention that in their account of what happened that day, and if it’s more like 50%, then you have a problem. Here are some interestingly discordant testimonies that I came across during my search: Antonio dos Ramos Mira, local resident: A quarter of an hour after the rain stopped, he saw that huge crowd of people, in great clamor and almost all kneeling, facing the sun, which had unusual signs, turning around, trembling, observing at the same time that a yellow-reddish color had appeared around him, which was reflected throughout the crowd and on the horizon, with at the same time a weakening of light and an increase in temperature. The crowd, even the unbelievers, said that it was a known miracle. This is in the third person because the priest and clerk conducting the investigation are summarizing an account being given by an illiterate peasant. The witness names one color - yellow-reddish - and doesn’t mention the sun falling to earth. Antonio Maria Menitra, local property owner: It had rained heavily in the morning, and a little after noon, the rain stopped, and he observed a large crowd of people kneeling down and looking at the sun. He also looked and saw different colors in the sun and in the people. No mention of the sun dancing, spinning, shooting off sparks, or approaching the earth. Joao Martia Lucio Serra, lawyer: Already in some candid souls arose the fear that the foretold event might not occur, when suddenly the entire immense crowd stirred at the seer's voice in a significant brouhaha of astonishment and wonder, raising their heads to the sky, where thousands of eyes gazed in amazement at the sun in full blue, visible to all, without the intensity of its rays harming the retina and hindering vision, crowned with various colors, in a rapid rotation, at times seeming to detach itself from the celestial vault, approaching the earth. The spectators, looking at each other, represented themselves to each other as yellow, and on the horizon, reddish-orange, wherever their eyes looked, they saw beams of dim light, affecting an oval shape, seemingly placed at equal distances, and reflecting on the earth. Nobody else mentions the “beams of dim light, affecting an oval shape, seemingly placed at equal distances”. Maria Augusta Saraiva Vieira de Campos, local resident: Our sense of discouragement was profound, when suddenly we heard from all sides: Miracle! Look at the sun! The rain had stopped as if by magic; hats were closed; a warmth was felt as if we had entered a heated greenhouse, and the disk of the sun began to be seen, clearly discernible in the brownish layer that covered the entire sky. The heat increased, and the sun seemed to sink lower and lower, presenting new and varied changes. We saw a silvery veil, rounded in shape, as if it were a full moon; shortly after, it turned to vivid purple, then red, then emerald green, and finally took on its original color. Cries were heard from all sides as it emerged from the sun like a white, shining snow-like shape, without harming the retina, coming toward us, returning to the sun again, and finally hiding for the third time among the clouds. Everyone wept, and prayers, supplications, and acts of faith were heard from many mouths. Now something is coming down off the sun, instead of the sun itself coming down. Also, the colors are purple → red → green. Goncalo Xavier de Almeida Garrett, mathematics professor: 1st: The phenomena lasted about 8 to 10 minutes; 2nd: The sun lost its dazzling brightness, taking on the appearance of the moon and being easily seen; 3rd: The sun, three times during this period, manifested a rotational movement on its periphery, flashing sparks of light on its edges, similar to what happens with the well-known firework wheels; 4th: This rotational movement of the sun's edges, manifested 3 times and 3 times interrupted, was rapid and lasted 8 or 10 minutes, more or less; 5th: Next, the sun took on a violet color and then an orange, spreading these colors over the earth, finally regaining its brightness and splendor, impossible to be seen with the eyes; 6th: It was shortly after noon and near the zenith (which is very important) that these facts occurred. Do mathematicians really number everything they say like this? We saw this account earlier, and in most ways it matches the consensus story. But even though he’s trying to be methodical, he totally fails to mention the sun descending to crush the world. Instead, it’s the rotational movement that happens three times. Also, the colors are violet → orange Luis Antonio Vieira de Magalhaes e Vasconcelos, nobleman: I was absolutely convinced that I would see nothing. I then remembered, as I had remembered many times before, that principle of Gustave Le Bon, which boils down to the hypnotic current that dominates it. I had to be cautious, not to be influenced. This friend of mine, taking out his watch, said to me: there are five minutes left, at one o'clock look at the sun, that was the time announced by the shepherdesses, then you will tell me. My friends shout to me: look, look, but at first I only saw clouds drifting by, leaving the sun uncovered. Suddenly, I see an intensely pink rim, surrounding the sun, which resembled a disc of dull silver, as someone once said, while giving me the impression that it was moving from its original position. Diaphanous, vaporous clouds, somewhat purple, somewhat orange, permeated the air. At various points along the horizon, contrasting with the leaden hue of the sky, I also saw pink and yellow spots. The clamor grew louder and louder. This didn't last seconds: perhaps minutes. As I observed these manifestations, which I never doubted for a moment were due to the Infinite Omnipotence of God, an indescribable impression came over me. Here are the silver disc and the unusual colors (here “pink, purple, and orange”). But the colors are now merely “clouds” and “spots”, and there is nothing about spinning, dancing, or falling to earth. Antonio de Paula, pilgrim from Lisbon: Suddenly the priest looks at the sun and says that the sun in eclipse was not like that. The deponent also looked and saw that the sun gave no light; a white mist hung over it, it was a dull moon. The sun was to the left, with the rest of the sky obscured. Taking his eyes off the sun, he saw the people a very bright red color; and he exclaimed: "Oh, gentlemen, how the people are all red!" And the priest replied: "Are they red scarves?" To which he remarked: "How can that be? So they had all agreed to have red scarves on their backs?!" Then the people appeared the color of gold. The sun's rotational movements were not visible to them. The people on that occasion cried out loudly, kneeling with their hands raised, shouting for Our Lady, not caring about the thick mud, repeatedly invoking Our Lady. The people's impression was extraordinary. This person saw the silver moon-like sun and the color changes (here “red” and “gold”), but nothing else. He explicitly mentions not seeing the rotation. Luis de Andrade de Silva: The globe of the sun, similar to a disc of dull silver, rotated around an imaginary axis, and at that moment, it seemed to descend through the atmosphere, towards the earth, accompanied at times by an extraordinary brightness, and by an intense heat. The sun's rays were said to have yellow, green, blue and purple colors, but I only noticed the yellow color. After a few minutes, during which these phenomena occurred, no one could look at the sun anymore, because its rays hurt the retina. Only those who witnessed these phenomena can evaluate what happened then, but cannot describe them exactly. He says that although he heard other people mention yellow, green, blue, and purple colors, he only saw yellow. Dominic Reis, American traveler: The sun started to roll from one place to another place, and changed blue, yellow, all colors! Then we see the sun come toward the children, toward the tree. Everybody was hollering out. Some start to confess their sins, ‘cause there were no Priests around there . . . even my mother grabbed me to her and started to cry, saying, ‘It is the end of the world! And we see the sun come right into the trees. And then the little children get up and turn around to the people and told the people, ‘Pray and pray hard because everything is going to be all right.’ This person says the sun didn’t merely fall to earth, but went to the children (ie the child-seers) and the tree (the oak where the Virgin was appearing) in particular. At one point, it is specifically located “right [in] the trees”. But in this account, I am getting the impression that the “sun” is some sort of UFO-like object, maybe the size of a large helicopter, which is in a particular place. I can’t tell if other witnesses also thought this and just didn’t describe it clearly, or whether this testimony is discordant. The interviewer (Haffert again) notices this, and asks whether Reis really thinks it was the sun; Reis gives a weird non-answer (“Well, for my part it was the sun . . . but whether just a light or not, there was something there. I know for sure.”) Dominic Reis, continued from elsewhere in his account: As soon as the sun went back in the right place the wind started to blow real hard, but the trees didn’t move at all. The wind was blow, blow and in few minutes the ground was as dry as this floor here. Even our clothes had dried. We were walking here and there, and our clothes... we don’t feel at all. The clothes were dry and looked as though they had just come from the laundry. I believed. I thought: Either I’m out of my mind or this was a miracle, a real miracle. Although many people said their clothes were miraculously dry, Reis is the only one who mentions a miraculous wind. Everyone else says their clothes were dried by a miraculous heat. Reis does not mention heat. Maria dos Santos On October 13th, when Lucia said: "Our Lady is coming!", one of the deponent's daughters, named Maria, was standing on a rock, a meter from the holm oak tree, on the east side, to guard the bow so the people wouldn't damage it. The girl felt a blow to her face, saw a beautiful light near her, and cried out: "Oh! Our Lady!" The deponent looked and saw a star, a ball, not entirely round, like an egg, very beautiful, with the colors of the celestial rainbow, but much more vivid, with a tail of one and a half meters of brilliant colors. It passed very quickly and close to the holm oak tree, and disappeared a hand's breadth from the ground. She saw the sun sinking low. This is maybe the same UFO-like object that Dominic is reporting. In some of the other Fatima apparitions, the Virgin appears to those who cannot see her true form as a ball of light that comes to the tree where the child-seers are waiting. So maybe there were two things going on - the sun in the sky, and a ball of light (the apparition itself) heading back and forth to the tree. Still, if these are really two different phenomena, only these two accounts mention the second one. I don’t really have much that is non-obvious to say about these discordant testimonies. Aside from the ones with the UFO-like object, they seem about as discordant as you would expect from panicked people seeing a real inexplicable phenomenon - with the exception of some people who are absolutely terrified by the falling sun, and other people who don’t mention it at all. 1.4 Dalleur And The Distant Testimonies Maybe the only interesting advance in Fatimology in the last fifty years is Dalleur (2021), the focus of Muse’s Substack post. Dalleur is a philosophy professor at the Pontifical University in Rome, but clearly a multi-talented individual. He seems to lean toward the “miracle” explanation, but asks a fruitful question that nobody else seems to be considering: if it was a miracle, how was it implemented? That is, the real sun obviously didn’t change color or move - this would have been visible around the world, and would probably have fried the Earth. So what did God or the Virgin do, exactly, to produce the appearance of a moving sun? We can imagine two possibilities. First, they could have implemented the miracle through a “prophetic vision”, where they inspire a sort of mass hallucination in the onlookers. Second, they could have created some kind of objectively-real fiery wheel object in the skies above Portugal, and arranged for people to mistake it for the sun. If they did the second, we should be able to pin down where exactly they created it by triangulating distant testimonies Dalleur and I both found four of these: Joaquim Lourenco, schoolboy, 9 miles from Fatima: I feel incapable of describing what I saw. I looked fixedly at the sun which seemed pale and did not hurt my eyes. Looking like a ball of snow, revolving on itself, it suddenly seemed to come down in a zigzag, menacing the earth. Terrified, I ran and hid myself among the people, who were weeping and expecting the end of the world at any moment. It was a crowd which had gathered outside our local village school and we had all left classes and run into the streets because of the cries and surprised shouts of men and women who were in the street in front of the school when the miracle began. There was an unbeliever there who had spent the morning mocking the ‘simpletons’ who had gone off to Fatima just to see an ordinary girl. He now seemed paralyzed, his eyes fixed on the sun. He began to tremble from head to foot, and lifting up his arms, fell on his knees in the mud, crying out to God. But meanwhile the people continued to cry out and to weep, asking God to pardon their sins. We all ran to the two chapels in the village, which were soon filled to overflowing. During those long moments of the solar prodigy, objects around us turned all colors of the rainbow... When the people realized that the danger was over, there was an explosion of joy. Albano Barros, young boy, 12 miles away: I was watching sheep, as was my daily task, and suddenly there, in the direction of Fatima, I saw the sun fall from the sky. I thought it was the end of the world. I was so distracted that I remember nothing but the falling sun. I cannot even remember whether I took the sheep home, whether I ran, or what I did. Guilhermina Lopes da Silva, local resident, 16 miles away: I could not go [to Fatima] because my husband was an unbeliever. I was looking toward the mountain at noon when suddenly I saw a great red flash in the sky. I called two men who were working for us. They, of course, saw it, too. Afonso Vieria, famous writer, 30 miles away On that day of October 13, 1917, without remembering the predictions of the children, I was enchanted by a remarkable spectacle in the sky of a kind I had never seen before. I saw it from this veranda… Dalleur pins these on a map, which I’ve edited slightly for clearer labeling: The furthest report is 34 km (21 miles) away from Fatima, so Dalleur concludes the phenomenon was visible from about this distance. Further, all witnesses outside Fatima said the phenomenon was coming from the direction of Fatima, not from the direction of the sun (which in some cases was directly opposite Fatima)! By triangulating the accounts, Dalleur estimates that the miraculous light source which appeared to be the sun: was probably located above the hills a few km south of the Cova da Iria [in Fatima]. …ie at the spot indicated by the black sun sign in the purple circle on the map. Dalleur moves on to analyzing photographs of the event: He tries to estimate the angle of the shadows, and, from there, the angle of the light source. I cannot entirely follow his calculations, but he finds that there are two light sources - a diffuse source at about 42° elevation, and a point source at about 30°. The 42° source corresponds to the elevation we would expect the sun to be at in southern Portugal on October 13 around solar noon. It’s diffuse because it’s hidden behind clouds, just as it was all morning. So what is the 30° light source? Dalleur suggests it’s whatever object the witnesses are describing as spinning, moving, and changing color. They’re mistaking it for the sun because the real sun is hidden behind clouds. For a bright round sun-sized object in the sky during the day not to be the sun, isn’t really in most people’s hypothesis space. The paper stops here, but I’m not sure why. Given a distance, an angle, an apparent size (the size of the sun disc), and basic trigonometry, you should be able to calculate the object’s elevation and true size. Do this, and you find that the light source is two miles high and about 200 feet in diameter. That’s about the size of a 747, at about half the 747’s usual cruising altitude. What, who did you think God drafted to play “terrifying spinning fiery disc”? 1.5: Making Sense Of The Testimonies The multitude of testimonies of Fatima may trick us into thinking we understand what the miracle looked like. This complacency deserves to be challenged: “The sun looked pale, like the moon, and was painless to gaze upon”: Most sources treat this as the first aspect of the miracle. Several talk about how unbelievers are going to think it was just fog, but this can’t be true, because the edge of the solar disc was clearly defined, or there was no fog halo, or some other reason like that - and therefore even this first step was clearly miraculous. I feel like I’m going crazy here - I see this regularly! Not often, but a few times a year. When the sun is sort of halfway behind certain types of thin cloud, it looks pale like the moon (I remember, as a child, being uncertain about whether the full moon was somehow out during the day and visible through clouds), is painless to gaze upon, and has a clearly defined edge. Am I hallucinating? I decided to resolve this the same way the new government of Nepal chose its prime minister - via Discord poll: Here’s one of the hits for “sun behind clouds” on Google Images: I don’t know if this is a real picture or used lenses or something, but it’s pretty true to my experience. So why does every previous commentator act as if this is some cosmic mystery to be explained? A few people argue that (although it was a generally cloudy day), the mystery is that the clouds were nowhere near the sun at this point, so they couldn’t have been causing the unusual pallor. But the majority of witnesses say the clouds were absolutely near, or veiling, or even covering the sun. Stanley Jaki makes this a central point of his book, saying that “The great majority of eyewitness accounts, and certainly the most important ones, contain emphatic references to the continued presence of clouds.” I’m going kind of crazy here. I notice that the holdouts on my Discord poll disproportionately come from my non-Californian friends - is this rarer in other locales? I’m not sure. In any case, I will not count this as being one of the mysterious aspects of the miracle requiring explanation. “The sun was spinning”: How can a featureless disc be seen to spin? Despite this being one the most commonly-reported aspects of the miracle, almost nobody explains this point. Some say that only the rim was spinning, but this has the same problem. However, several people compared the sun to a “firework wheel”, also called a “Catherine wheel”. Here is a video of this object, which apparently was well-known in the Portugal of the time: Stanley Jaki relates a story about a priest having this same question and grilling a witness; the witness finally claimed that the sun traced a circle (like a basket in a Ferris wheel) rather than merely rotating. But this contradicts several claims that it “rotated around its own axis”, and I wonder if the witness was intimidated by the seeming contradiction in her story and was trying to weasel out of her own confusion. If we treat the miracle as the result of some kind of illusion, this becomes slightly easier to explain; there are plenty of visual distortions that look like a spinning motion, and since it is the visual field itself that is spinning, rather than any particular object, it can be seen whether the object is a disc or not. “The sun seemed to fall to earth”: In what sense did it seem like this? If the sun had simply gone down in the sky, people would have said it was setting, the same way it does every evening. One witness does say this. Most other witnesses say it was terrifying, and they felt like they (as opposed to other people living near the horizon) were about to be crushed. If the sun had simply gotten bigger - wouldn’t people have just said it looked bigger? Isn’t this a more natural way to record that the sun’s disc seemed to expand? Fr. Jaki combs his selection of witness accounts (larger than mine), but is only able to find one person who says “it got bigger” in so many words, compared to the dozens who talk about it looming, or falling to earth. Some people say that the sun “left the sky” or “left its place in the sky” at this point. In what sense? If the object that appeared to be the sun at Fatima had been visible as an object of a particular size (let’s imagine it as a flying saucer), then not only would this have been remarked upon, but it would have appeared to threaten some parts of the crowd in particular (that is, a descending saucer would look like it was about to land on some specific area). But this is not the consensus description, and several people say they thought the sun might crush the entire world. Several witnesses say it approached Earth with a jerky or zig-zag motion. If I imagine something else approaching Earth - let’s say a jumbo jet or asteroid - I can tell that it’s approaching rather than getting bigger because there’s multiple components to its trajectory that let me separate size change from forward movement. When I think of this aspect, I imagine the sun very suddenly growing in size and brightness to take up a substantial fraction of the sky (maybe >50%?!), maybe with some jerky motion on the side. Although it’s hardly scientific, I was charmed by John Touhey’s project of trying to visualize the miracle by using witness descriptions as prompts for ChatGPT. His work is a year old, and so several GPT iterations out of date. When I repeat his work with the current version, I get these: Interlude: The Anti-Clerical Union As mentioned briefly before, 1910s Portugal was in a period of transition. In 1910, a group of proto-socialist revolutionaries overthrew the monarchy. The monarchy and church had been in cahoots, so the revolutionaries cracked down on Catholicism, closing the monasteries and persecuting the churches. This was a bold move - only an upper crust of educated urbanites were proto-socialist, and 99%+ of the country identified as Catholic, albeit at various levels of religiosity. In the 1920s, conservatives would regain the upper hand, overthrow the proto-socialists and restore a pro-church dictatorship. Still, the small urban educated ruling class of 1910s Portugal was a hotbed of atheistic anti-church sentiment. Probably the child-seers of Fatima were only dimly aware of this, but their prophecies were a spark entering a powder keg, and many of the more worldly witnesses were aware of this context. While reading through Fatima-related documents, I came across some pamphlets by Grupo Anticlerical, one of the era’s leading atheist organizations. They are totally irrelevant to our primary goal of trying to figure out what’s up with the miracle. But I love them so much that I can’t resist adding one as an interlude. I have slightly edited the machine translation for clarity and readability: To defend the sacred freedom of conscience—guaranteed by the original Law of Separation of Church and State—from the furious attacks of implacable Jesuitism—the greatest enemy of all human happiness!—the Anticlerical Group was organized in this town, similar to what is being done in many parts of the country! This was necessary. They call us to fight. We present ourselves courageously! The great, formidable battle of progress against Ultramontane Reaction, of Freedom against Tyranny, of Truth against Lies is waged again with enthusiasm and ardor! The redemptive dawn that the Portuguese people saw emerge on October 5, 1910, is about to be eclipsed, intercepted by the immense flood of black cassocks!... But in the dark night that seeks to envelop Reason; where moral suffering takes on tragic proportions in a frightening asphyxiation, the Light will once again break through!... the consoling light of elevated spirits... and like a sinister scarecrow, the grim reaction will flee in terror! Liberal people! Hear us! This fight is terrible! Many of our people will perhaps be crushed and tortured on the battlefield, but what does it matter?! Every war against reaction is a holy war because it frees consciences from the clutches of their enemies!... It is the fight of Justice against Iniquity, of Love against Hate, of Good against Evil!... To the fight, then, for the Progress that makes life beautiful; for the Freedom that redeems the people; and for the science that guides us all as an eternal beacon to the Light of Truth! Gago Coutinho and Sacadura Cabral [two Portuguese aviators who had recently flown across the Atlantic] are prodigious spirits before whom our souls kneel religiously – boldly breaking through the air with the mathematical certainty of someone who knows the path to be taken to get from one point to another determined point; flying through the immense blue as sure of their route as any of us walking on earth, they showed us that Science is not an empty word! The power of their prodigious sextant, the fruit of immense scientific lucubrations, is more real and positive than the cross of Christ painted on their device, which could not even have saved them from falling due to lack of gasoline in the middle of the sea at the mercy of the waves. Their extraordinary journey, an adventure which moved us to tears, was the most resounding scientific victory of recent times! It was, above all, a powerful affirmation of science! Let us therefore make science our religion, for scientific religion is Freedom of Thought! To be a Free Thinker is to love immortal science, eagerly waiting for it to reveal to us the truth of the great enigmas of the Universe! And only it can reveal them! People! Let us always fight! From the victory of progress, science, freedom, and free thought, will result human happiness, joy, love, fraternity, respect for women, veneration for mothers, adoration for children, affection for the elderly, protection for the sick, the unfortunate, the tortured. The victory of reaction, of clericalism, of black, cruel and ferocious Jesuitism will result in: the gallows, the acts of faith with their human destruction, persecution, exile, robbery, arson, the deflowering of women, the killing of children, the monstrous torture of all free spirits! The history of so many crimes committed in the name of God horrifies us! The Inquisition, relentlessly slaughtering, tearing, and burning the flesh of so many victims, is still today, in the twentieth century, a sinister specter haunting us!... O most holy mothers! O holy, pious mothers who so love your sweet little children! Have compassion on your beautiful little children, sacred fruits of your blessed wombs: Love Freedom! Love Liberty, O loving mothers, immaculate saints of our altar! We pray for them... for your children, who are the light of your candid eyes, the life of your life... for little children... for all children, tender rosebuds that retrogression furiously lashes, – love Liberty!. And you, O parents! Heads of families who so tremble at your loved ones, snatch them from the merciless clutches of the reactionaries who twist their brains and kill their reason! Hear us all, men, women, and children; listen: Freedom writhes in horrible convulsions... it vibrates in space, echoing from mountain to mountain, an anguished cry for help!... It is Freedom that falls, annihilated! It is Freedom that dies in the bloody clutches of Jesuitism! The Miracle of Fatima, people, is a ridiculous lie, it is a comedy, it is not religion! Come on, liberals! Let us all rise up from this criminal apathy and, without delay, fight not the religious sentiment of the Portuguese people, such a good people, a race of heroes, but rather the exploitation that clericalism is inflicting on the people, foisting upon them, at a good price, images of the saint —trademarked to avoid competition from other vampires! —the shamelessness!—and leading them, through suggestion, to wallow and drink madly, the miraculous water, foul, filthy water, full of rot, pus, and pestilent microbes that the sore flesh of the sick leaves deposited there in the washings! We, all as one man, will fight the reaction, forcing it to retreat and thus, with our efforts, we will save the Republic and the Portuguese Land from its fatal annihilation! … …anyway, Interlude over, let’s get back to the miracle. 2: The Skeptical Explanations Re-invigorated by the rousing prose of Grupo Anticlerical, can we come up with a materialist explanation for the sun miracle? 2.1: Pilgrim, Avert Thine Eyes Starting in October 1917, doubters have focused on one obvious possibility: staring at the sun is harmful to your health. If you stare too long, you go blind. If you stare just slightly less long than that . . . maybe something strange happens? Just to get a particular theory out there: everyone knows that if you stare at a bright light source for a few seconds, you get a temporary afterimage - often pink or bluish-green - on your retina. Suppose the pilgrims stared at the sun. Their eyes would inevitably make microsaccades - small natural jerking motions - and the afterimage would appear somewhere slightly different than the true sun. This might look like the sun turning pink or blue and moving in a zig-zag pattern. Believers in the miracle counter this proposal in several ways. First, although it might explain the sun changing colors and dancing, it doesn’t give an explanation for spinning, sparkling, or falling to earth and threatening to crush everybody (exactly three times in a ten minute interval, no less). Second, although witnesses describe the sun changing color, they also describe everything around them changing color to match the sunlight, which doesn’t match localized afterimages. And one scientifically-minded witness specifically describes closing his eyes to see if there was a persistent afterimage; he says there was not. Third, there are no reports of eye injuries or blindness from a crowd that was, supposedly, staring straight at the sun for ten minutes. This is a good match to witness reports (that the sun was unusually pale and didn’t hurt to look at) and with Dalleur’s theory (that it wasn’t the sun). But it’s a bad match to any theory depending on eye injuries. Fourth, this would require Portuguese people to be total idiots. Everyone already knows bright lights cause afterimages. Surely if you stare at the sun for ten minutes and get some afterimages, you’re not going to freak out and start screaming about miracles and the end of the world. Even if the peasants had somehow remained ignorant of afterimages their whole lives, the scientists and doctors in attendance wouldn’t be fooled. If we are to keep this theory, maybe we should posit some retinal phenomenon much stronger than the ones we know. Everyone thinks they know how much an illusion can fool you - “yeah, okay, obviously the cookie that looks very slightly bigger will actually be the same size” - which is exactly why the really good ones, like the Checker Shadow Illusion, come as such a shock. Squares A and B are the same color. Source: Checker shadow illusion. There’s no way around it: we need to hear from someone who has stared directly into the sun. August Meessen was a physics professor at a Catholic university, which sounds like exactly the job profile we want for this sort of thing. He found himself sufficiently interested in the Fatima miracle to stare straight into the sun for a few minutes and record what happened. From his paper: In November 2002, I looked directly into the sun, at about 4 p.m. The sun was relatively low above the horizon and its light intensity was attenuated, although the sky was clear. I was able to look right into the sun and was amazed to see that the sun was immediately converted into a grey disc, surrounded by a brilliant ring. The grey disc was practically uniform, while the surrounding ring was somewhat irregular and flamboyant, but did not extend beyond the solar disk. It coincided with its rim. I stopped the experiment, since I wanted to be prudent, but I had experienced myself the initial phase of a typical “miracle of the sun” and I could explain it. The sun became grey, since my eyes immediately responded to its great luminosity by an automatic reduction of their sensitivity. This adaptation is not simply due to the bleaching of pigments in the colour-sensitive cones of the fovea, where the image of the sun is projected, but to secondary processes. By “initial phase”, he means the part where the sun looks pale and well-defined, like a full moon. This isn’t something I think needs explanation (see above), but he sure has explained it. Moving on: In a second experiment, realized at 3 p.m. in December 2002, I looked straight at the sun during a much longer time. After some minutes, I saw impressive colours, up to 2 or 3 times the diameter of the sun. They changed, but were mainly pink, deep blue, red and green. Further away, the sky became progressively more luminous. I stopped there, since I understood that these colours resulted from the fact that the red, green and blue sensitive pigments are bleached and regenerated at different rates. This is frustratingly vague. Are the “impressive colors up to 2-3 times the diameter of the sun” just the normal aftereffects of staring at a bright object? Or something surprising even to physics professors? And the spinning? What about the motions of the sun? I didn’t see them, because I didn’t look at the sun for a sufficiently long time or my brain knew already too much. Once, after I had been looking at a very long passing train, I had (for about 30 seconds) the illusion of an opposite motion. Joseph Plateau discovered that when we look at the centre of a spiral that is rotating at some given velocity about this point, and when we stop this rotation, we see a reversed rotation. It lasts for several minutes, although in reality, there is no motion at all. This is a good example of motional after-effects. The “dance of the sun” is initiated, however, by a spontaneous generation of apparent motion. This feels suspiciously like a just-so story. His explanation for the sun falling to earth to crush everyone - which he also did not see - is equally ad hoc: A very interesting study was recently devoted to this “zoom and loom effect”. It tends to appear when the brain is confronted with the two-dimensional retinal image of an object that is situated at some unknown distance. The brain will then consider the possibility that it could come closer, by performing an illusory mental zoom, where the apparent size of the object is progressively increased. This results from the fact that evolution preserved the tendency to take into account the possibility of a dangerous approach: a rapid evasive action could be beneficial for survival. If true, it sounds like you should be able to generate this effect not just by staring at the sun (ill-advised, causes blindness), but by staring at the moon. I would like to test this, but unfortunately I am writing this on the night of a new moon; I’ll check back in two weeks. Still, I am skeptical that no human being living before 1917 AD ever figured out that staring at a celestial body long enough would make it appear to fall to earth and crush you. Compare to much gentler illusions - like how the moon looks bigger right when it starts to rise - which everybody knows about. I was able to find a thirdhand report (Fr. Stanley Jaki → G. J. Strangfeld → consultation with bishop) of another sun miracle investigator, one “Professor Dr. Stöckl” in Germany, who made a similar experiment: After almost a minute (the time varies according to the condition of the atmopshere and the momentary condition of the eyes) one thinks to see a dark blue disk in front of the sun (this is already a sign of the highly excited state of the retina). According to my experience … this dark blue disk is somewhat smaller than the solar disk, so that the edge of that disk stands out as a ring beyond that dark blue disk. Then one has right away the impression that the solar disk rotates with great speed in one or the other direction. This I have experienced often enough. All this is a subjective appearance that has nothing to do with the external world. These reports are suggestive, but weaker than all but the barest Fatima testimonials. Dr. Messeen admits as much, saying that “I didn’t look at the sun for a sufficiently long time”. Can we find people even more committed - or reckless, or masochistic - than Professors Messeen and Stöckl? Absolutely yes: there was a whole subfield of late 18th / early 19th century psychophysicists who experimented with staring at the sun for long periods, many of whom went blind. Joseph Plateau (1801 - 1883, went blind in 18432) summarizes their work in his aptly-named On The Contemplation Of Bright Objects. He lists twenty-six scientists who tried staring at the sun for a really long time. Most describe what we now recognize as typical retinal afterimages, and Plateau spends most of his time talking about how long these last and what colors they pass through. The only one of Plateau’s sources who reports anything even slightly interesting to us is Robert Darwin (father of Charles; cf. Secrets of the Great Families). After stating that: The author has frequently observed that when he gazed at the midday sun for a long time, until its disk appeared pale blue, he saw a bright blue specter on other objects for more than two days. …he mentions how When looking at the meridian sun as long as the eyes can well bear its brightness, the disc first becomes pale, with a luminous crescent, which seems to librate from one edge of it to the other owing to the unsteadiness of the eye. Here is pallor, and at least a hint of motion. But it’s pretty different from spinning, and not really clear how it relates to the sun miracle. Gustav Fechner (1801 - 1887, went blind in 1839) may have stared for even longer; you can read more of his story - including his ensuing insanity and subsequent attempts to found a new religion - on Adam Mastroianni’s blog. But all that he records about his ill-fated experiment is that: …after looking at the sun through homogeneously colored lenses, if you close your eyes, the primary impression remains for a long time and the entire afterimage usually disappears without a complementary coloration having clearly emerged. These people are great, and they all sound like minor Sam Kriss characters. But after whole careers dedicated to staring at the sun much longer than any normal person would ever try, they report only the barest hints of odd phenomena. Indeed, if anything they saw less of interest to the Fatimologist than Profs. Messeen and Stöckl. Worse, all of these authorities saw their phenomena after seconds to minutes of deliberate staring. Surely if it had taken a minute of staring at the sun before anything happened, some of our eyewitnesses would have mentioned this; after all, several mention that they were starting to doubt after the child-seers’ deadline had passed a few minutes earlier. But by all accounts, the miracle was near-instantaneous. Although Messeen and Stöckl’s reports of miracle-like phenomena are intriguing, it doesn’t seem like they can be the whole picture. Let’s move on. 2.2: Aurora Borealis? At This Time Of Year? In This Part Of The Country? Localized Entirely Within Your Kitchen? Could the miracle at Fatima have been some kind of weird weather phenomenon? The main argument against is that if it were a common weather phenomenon, it would not have awed and terrified tens of thousands of people. But if it were a rare weather phenomenon, then the seers’ successful prophecy that the rare weather phenomenon would happen at solar noon on October 13 1917 becomes almost as impressive as an outright miracle. The argument in favor is that dozens of people have written books and papers about this possibility, we would feel remiss if we didn’t mention them, and anyway it gives us the opportunity to look at pretty pictures of interesting weather phenomena. This is a sun dog. It’s caused by ice crystals in the upper atmosphere that refract sunlight in a very specific way. It’s very cool, but aside from a resemblance to a wheel, it looks nothing like the miracle of Fatima. A sun dog doesn’t have any unusual colors, it doesn’t change size, and it doesn’t spin (I’ve embedded a YouTube video not because a still image would be misleading - it wouldn’t be - but just in case you want to see for yourself how completely motionless it is). It’s just a halo shape with two smaller illusory suns on either side of the real one - something which no one at Fatima reported. (source) This is a solar corona3; cloud iridescence is a related phenomenon. I don’t know how much work the exposure length is doing in this particular photo, but I’m guessing more than zero. Coronae are also very pretty, and might explain the description of wheels and colors. They seem surprisingly common for something that I can’t ever remember seeing, supposedly happening several times a year in most locations. But they don’t spin, the colors don’t change or stain the surrounding landscape, and they don’t fall to earth and crush people. Let’s keep this one as a backup option and move on. This is a dust storm. Steuart Campbell wrote a paper arguing that the miracle was caused by one of these, and I admit if I saw this I would start praying pretty hard. Dust storms can change the color of the sun (including unusual colors like green or blue). And very, very charitably, whirling dust could look like the sun itself spinning around, and the thickening and thinning of dust could look like the sun approaching or receding. But this would require a dust storm localized to a 20 mile region of Portugal which does not, technically, have any dust (and where it was, technically, raining at the time). Campbell proposes that perhaps a storm blew a 20 miles x 20 mile dust cloud from the Sahara out to the Atlantic, then onto Fatima for ten minutes during a break in the rain, then back to the Atlantic again. But I don’t think any dust storm has ever behaved in quite this way. If it did, it probably wouldn’t be at the exact moment predicted by child-seers months in advance. At this point, we might as well talk about literal meteors. The way I’m imagining it is this: as a meteor approaches Earth, it breaks up into three big parts and a host of smaller particles. They strike the atmosphere head-on, from the approximate direction of the sun. The small particles hit first and make a firework show. Then the three big pieces hit, producing multicolored fireballs (meteors can absolutely stain the sky bright colors - see the video). Finally, they burn out a few miles above the ground, , convincingly producing the appearance of the sun falling to earth and nearly striking the spectators. This could even explain the warmth and dry clothes - a local meteor strike produces a lot of heat! I like this because it’s the only one that takes seriously the facet of the event which most impressed the witnesses - the part where it looked like the sun was plummeting to earth and about to kill them. But against it: would a rain of micrometeorites really look like the sun was “dancing”, “spinning”, or “zig-zagging”? Aren’t most nearby meteor strikes very loud? (the Fatima event was, according to witnesses, silent) Don’t they usually break windows? Aren’t most meteor strikes of this size visible for hundreds of miles, not just the twenty miles from which we have witness testimonies? Wouldn’t the strike have to be remarkably head-on, and remarkable close to the position of the sun, in order to look like a solar phenomenon rather than a long streak? Aren’t most meteor fireballs visible for between a few seconds and a minute, not the ten minutes of the Fatima event4? And if there were some extremely unusual meteor strike that was the exception to everything, wouldn’t it still be pretty surprising for it to happen at the exact time and place predicted by child-seers months in advance? We come to the unpromisingly-titled Derivation of equations of the model of the dynamic behavior of the three-dimensional atmospheric cloud of electrically charged ice crystals under the influence of electrostatic forces, in which Artur Wiroski argues that Fatima was a three-dimensional atmospheric cloud of electrically charged ice crystals under the influence of electrostatic forces. Actually, he offhandedly mentions Fatima in three sentences, with the majority of the paper looking more like the image above - but he eventually makes it into a Guardian article where he emphasizes that yes, he is trying to explain the miracle of the sun. However, if I’m understanding him correctly, he says that his theoretical ice crystal phenomenon can only happen when the sun is at an altitude below 22 degrees. But during the Fatima miracle, the sun was at 42 degrees (and Dalleur’s mysterious light source was at 30 degrees), so none of this applies. I’ve tried to include pictures of all the phenomena I mention in this section. I failed for this one, because it’s never been spotted or photographed. It’s just some incredibly weird thing that one scientist says ice crystals might do if parameters were ever exactly right, with such a precise definition of “exactly right” that it’s never happened in real life. If it ever did happen, it probably wouldn’t be at exactly the moment predicted by child-seers several months in advance. 2.3: Everyone’s Mad Here Except You And Me Another common response calls the Sun Miracle a “mass hallucination”. Can 70,000 people really hallucinate the same thing? “Mass hallucination” on Wikipedia redirects to List Of Mass Panic Cases. The Miracle of the Sun is on there, but listed as “(disputed)” - the only item to earn such a parenthetical. The other fifty items mostly belong to three categories: A disease with unusual symptoms spreads through a population; doctors eventually pronounce it psychosomatic.

The furthest report is 34 km (21 miles) away from Fatima, so Dalleur concludes the phenomenon was visible from about this distance. Further, all witnesses outside Fatima said the phenomenon was coming from the direction of Fatima, not from the direction of the sun (which in some cases was directly opposite Fatima)! By triangulating the accounts, Dalleur estimates that the miraculous light source which appeared to be the sun: was probably located above the hills a few km south of the Cova da Iria [in Fatima]. …ie at the spot indicated by the black sun sign in the purple circle on the map. Dalleur moves on to analyzing photographs of the event: He tries to estimate the angle of the shadows, and, from there, the angle of the light source. I cannot entirely follow his calculations, but he finds that there are two light sources - a diffuse source at about 42° elevation, and a point source at about 30°. The 42° source corresponds to the elevation we would expect the sun to be at in southern Portugal on October 13 around solar noon. It’s diffuse because it’s hidden behind clouds, just as it was all morning. So what is the 30° light source? Dalleur suggests it’s whatever object the witnesses are describing as spinning, moving, and changing color. They’re mistaking it for the sun because the real sun is hidden behind clouds. For a bright round sun-sized object in the sky during the day not to be the sun, isn’t really in most people’s hypothesis space. The paper stops here, but I’m not sure why. Given a distance, an angle, an apparent size (the size of the sun disc), and basic trigonometry, you should be able to calculate the object’s elevation and true size. Do this, and you find that the light source is two miles high and about 200 feet in diameter. That’s about the size of a 747, at about half the 747’s usual cruising altitude. What, who did you think God drafted to play “terrifying spinning fiery disc”? 1.5: Making Sense Of The Testimonies The multitude of testimonies of Fatima may trick us into thinking we understand what the miracle looked like. This complacency deserves to be challenged: “The sun looked pale, like the moon, and was painless to gaze upon”: Most sources treat this as the first aspect of the miracle. Several talk about how unbelievers are going to think it was just fog, but this can’t be true, because the edge of the solar disc was clearly defined, or there was no fog halo, or some other reason like that - and therefore even this first step was clearly miraculous. I feel like I’m going crazy here - I see this regularly! Not often, but a few times a year. When the sun is sort of halfway behind certain types of thin cloud, it looks pale like the moon (I remember, as a child, being uncertain about whether the full moon was somehow out during the day and visible through clouds), is painless to gaze upon, and has a clearly defined edge. Am I hallucinating? I decided to resolve this the same way the new government of Nepal chose its prime minister - via Discord poll: Here’s one of the hits for “sun behind clouds” on Google Images: I don’t know if this is a real picture or used lenses or something, but it’s pretty true to my experience. So why does every previous commentator act as if this is some cosmic mystery to be explained? A few people argue that (although it was a generally cloudy day), the mystery is that the clouds were nowhere near the sun at this point, so they couldn’t have been causing the unusual pallor. But the majority of witnesses say the clouds were absolutely near, or veiling, or even covering the sun. Stanley Jaki makes this a central point of his book, saying that “The great majority of eyewitness accounts, and certainly the most important ones, contain emphatic references to the continued presence of clouds.” I’m going kind of crazy here. I notice that the holdouts on my Discord poll disproportionately come from my non-Californian friends - is this rarer in other locales? I’m not sure. In any case, I will not count this as being one of the mysterious aspects of the miracle requiring explanation. “The sun was spinning”: How can a featureless disc be seen to spin? Despite this being one the most commonly-reported aspects of the miracle, almost nobody explains this point. Some say that only the rim was spinning, but this has the same problem. However, several people compared the sun to a “firework wheel”, also called a “Catherine wheel”. Here is a video of this object, which apparently was well-known in the Portugal of the time: Stanley Jaki relates a story about a priest having this same question and grilling a witness; the witness finally claimed that the sun traced a circle (like a basket in a Ferris wheel) rather than merely rotating. But this contradicts several claims that it “rotated around its own axis”, and I wonder if the witness was intimidated by the seeming contradiction in her story and was trying to weasel out of her own confusion. If we treat the miracle as the result of some kind of illusion, this becomes slightly easier to explain; there are plenty of visual distortions that look like a spinning motion, and since it is the visual field itself that is spinning, rather than any particular object, it can be seen whether the object is a disc or not. “The sun seemed to fall to earth”: In what sense did it seem like this? If the sun had simply gone down in the sky, people would have said it was setting, the same way it does every evening. One witness does say this. Most other witnesses say it was terrifying, and they felt like they (as opposed to other people living near the horizon) were about to be crushed. If the sun had simply gotten bigger - wouldn’t people have just said it looked bigger? Isn’t this a more natural way to record that the sun’s disc seemed to expand? Fr. Jaki combs his selection of witness accounts (larger than mine), but is only able to find one person who says “it got bigger” in so many words, compared to the dozens who talk about it looming, or falling to earth. Some people say that the sun “left the sky” or “left its place in the sky” at this point. In what sense? If the object that appeared to be the sun at Fatima had been visible as an object of a particular size (let’s imagine it as a flying saucer), then not only would this have been remarked upon, but it would have appeared to threaten some parts of the crowd in particular (that is, a descending saucer would look like it was about to land on some specific area). But this is not the consensus description, and several people say they thought the sun might crush the entire world. Several witnesses say it approached Earth with a jerky or zig-zag motion. If I imagine something else approaching Earth - let’s say a jumbo jet or asteroid - I can tell that it’s approaching rather than getting bigger because there’s multiple components to its trajectory that let me separate size change from forward movement. When I think of this aspect, I imagine the sun very suddenly growing in size and brightness to take up a substantial fraction of the sky (maybe >50%?!), maybe with some jerky motion on the side. Although it’s hardly scientific, I was charmed by John Touhey’s project of trying to visualize the miracle by using witness descriptions as prompts for ChatGPT. His work is a year old, and so several GPT iterations out of date. When I repeat his work with the current version, I get these: Interlude: The Anti-Clerical Union As mentioned briefly before, 1910s Portugal was in a period of transition. In 1910, a group of proto-socialist revolutionaries overthrew the monarchy. The monarchy and church had been in cahoots, so the revolutionaries cracked down on Catholicism, closing the monasteries and persecuting the churches. This was a bold move - only an upper crust of educated urbanites were proto-socialist, and 99%+ of the country identified as Catholic, albeit at various levels of religiosity. In the 1920s, conservatives would regain the upper hand, overthrow the proto-socialists and restore a pro-church dictatorship. Still, the small urban educated ruling class of 1910s Portugal was a hotbed of atheistic anti-church sentiment. Probably the child-seers of Fatima were only dimly aware of this, but their prophecies were a spark entering a powder keg, and many of the more worldly witnesses were aware of this context. While reading through Fatima-related documents, I came across some pamphlets by Grupo Anticlerical, one of the era’s leading atheist organizations. They are totally irrelevant to our primary goal of trying to figure out what’s up with the miracle. But I love them so much that I can’t resist adding one as an interlude. I have slightly edited the machine translation for clarity and readability: To defend the sacred freedom of conscience—guaranteed by the original Law of Separation of Church and State—from the furious attacks of implacable Jesuitism—the greatest enemy of all human happiness!—the Anticlerical Group was organized in this town, similar to what is being done in many parts of the country! This was necessary. They call us to fight. We present ourselves courageously! The great, formidable battle of progress against Ultramontane Reaction, of Freedom against Tyranny, of Truth against Lies is waged again with enthusiasm and ardor! The redemptive dawn that the Portuguese people saw emerge on October 5, 1910, is about to be eclipsed, intercepted by the immense flood of black cassocks!... But in the dark night that seeks to envelop Reason; where moral suffering takes on tragic proportions in a frightening asphyxiation, the Light will once again break through!... the consoling light of elevated spirits... and like a sinister scarecrow, the grim reaction will flee in terror! Liberal people! Hear us! This fight is terrible! Many of our people will perhaps be crushed and tortured on the battlefield, but what does it matter?! Every war against reaction is a holy war because it frees consciences from the clutches of their enemies!... It is the fight of Justice against Iniquity, of Love against Hate, of Good against Evil!... To the fight, then, for the Progress that makes life beautiful; for the Freedom that redeems the people; and for the science that guides us all as an eternal beacon to the Light of Truth! Gago Coutinho and Sacadura Cabral [two Portuguese aviators who had recently flown across the Atlantic] are prodigious spirits before whom our souls kneel religiously – boldly breaking through the air with the mathematical certainty of someone who knows the path to be taken to get from one point to another determined point; flying through the immense blue as sure of their route as any of us walking on earth, they showed us that Science is not an empty word! The power of their prodigious sextant, the fruit of immense scientific lucubrations, is more real and positive than the cross of Christ painted on their device, which could not even have saved them from falling due to lack of gasoline in the middle of the sea at the mercy of the waves. Their extraordinary journey, an adventure which moved us to tears, was the most resounding scientific victory of recent times! It was, above all, a powerful affirmation of science! Let us therefore make science our religion, for scientific religion is Freedom of Thought! To be a Free Thinker is to love immortal science, eagerly waiting for it to reveal to us the truth of the great enigmas of the Universe! And only it can reveal them! People! Let us always fight! From the victory of progress, science, freedom, and free thought, will result human happiness, joy, love, fraternity, respect for women, veneration for mothers, adoration for children, affection for the elderly, protection for the sick, the unfortunate, the tortured. The victory of reaction, of clericalism, of black, cruel and ferocious Jesuitism will result in: the gallows, the acts of faith with their human destruction, persecution, exile, robbery, arson, the deflowering of women, the killing of children, the monstrous torture of all free spirits! The history of so many crimes committed in the name of God horrifies us! The Inquisition, relentlessly slaughtering, tearing, and burning the flesh of so many victims, is still today, in the twentieth century, a sinister specter haunting us!... O most holy mothers! O holy, pious mothers who so love your sweet little children! Have compassion on your beautiful little children, sacred fruits of your blessed wombs: Love Freedom! Love Liberty, O loving mothers, immaculate saints of our altar! We pray for them... for your children, who are the light of your candid eyes, the life of your life... for little children... for all children, tender rosebuds that retrogression furiously lashes, – love Liberty!. And you, O parents! Heads of families who so tremble at your loved ones, snatch them from the merciless clutches of the reactionaries who twist their brains and kill their reason! Hear us all, men, women, and children; listen: Freedom writhes in horrible convulsions... it vibrates in space, echoing from mountain to mountain, an anguished cry for help!... It is Freedom that falls, annihilated! It is Freedom that dies in the bloody clutches of Jesuitism! The Miracle of Fatima, people, is a ridiculous lie, it is a comedy, it is not religion! Come on, liberals! Let us all rise up from this criminal apathy and, without delay, fight not the religious sentiment of the Portuguese people, such a good people, a race of heroes, but rather the exploitation that clericalism is inflicting on the people, foisting upon them, at a good price, images of the saint —trademarked to avoid competition from other vampires! —the shamelessness!—and leading them, through suggestion, to wallow and drink madly, the miraculous water, foul, filthy water, full of rot, pus, and pestilent microbes that the sore flesh of the sick leaves deposited there in the washings! We, all as one man, will fight the reaction, forcing it to retreat and thus, with our efforts, we will save the Republic and the Portuguese Land from its fatal annihilation! … …anyway, Interlude over, let’s get back to the miracle. 2: The Skeptical Explanations Re-invigorated by the rousing prose of Grupo Anticlerical, can we come up with a materialist explanation for the sun miracle? 2.1: Pilgrim, Avert Thine Eyes Starting in October 1917, doubters have focused on one obvious possibility: staring at the sun is harmful to your health. If you stare too long, you go blind. If you stare just slightly less long than that . . . maybe something strange happens? Just to get a particular theory out there: everyone knows that if you stare at a bright light source for a few seconds, you get a temporary afterimage - often pink or bluish-green - on your retina. Suppose the pilgrims stared at the sun. Their eyes would inevitably make microsaccades - small natural jerking motions - and the afterimage would appear somewhere slightly different than the true sun. This might look like the sun turning pink or blue and moving in a zig-zag pattern. Believers in the miracle counter this proposal in several ways. First, although it might explain the sun changing colors and dancing, it doesn’t give an explanation for spinning, sparkling, or falling to earth and threatening to crush everybody (exactly three times in a ten minute interval, no less). Second, although witnesses describe the sun changing color, they also describe everything around them changing color to match the sunlight, which doesn’t match localized afterimages. And one scientifically-minded witness specifically describes closing his eyes to see if there was a persistent afterimage; he says there was not. Third, there are no reports of eye injuries or blindness from a crowd that was, supposedly, staring straight at the sun for ten minutes. This is a good match to witness reports (that the sun was unusually pale and didn’t hurt to look at) and with Dalleur’s theory (that it wasn’t the sun). But it’s a bad match to any theory depending on eye injuries. Fourth, this would require Portuguese people to be total idiots. Everyone already knows bright lights cause afterimages. Surely if you stare at the sun for ten minutes and get some afterimages, you’re not going to freak out and start screaming about miracles and the end of the world. Even if the peasants had somehow remained ignorant of afterimages their whole lives, the scientists and doctors in attendance wouldn’t be fooled. If we are to keep this theory, maybe we should posit some retinal phenomenon much stronger than the ones we know. Everyone thinks they know how much an illusion can fool you - “yeah, okay, obviously the cookie that looks very slightly bigger will actually be the same size” - which is exactly why the really good ones, like the Checker Shadow Illusion, come as such a shock. Squares A and B are the same color. Source: Checker shadow illusion. There’s no way around it: we need to hear from someone who has stared directly into the sun. August Meessen was a physics professor at a Catholic university, which sounds like exactly the job profile we want for this sort of thing. He found himself sufficiently interested in the Fatima miracle to stare straight into the sun for a few minutes and record what happened. From his paper: In November 2002, I looked directly into the sun, at about 4 p.m. The sun was relatively low above the horizon and its light intensity was attenuated, although the sky was clear. I was able to look right into the sun and was amazed to see that the sun was immediately converted into a grey disc, surrounded by a brilliant ring. The grey disc was practically uniform, while the surrounding ring was somewhat irregular and flamboyant, but did not extend beyond the solar disk. It coincided with its rim. I stopped the experiment, since I wanted to be prudent, but I had experienced myself the initial phase of a typical “miracle of the sun” and I could explain it. The sun became grey, since my eyes immediately responded to its great luminosity by an automatic reduction of their sensitivity. This adaptation is not simply due to the bleaching of pigments in the colour-sensitive cones of the fovea, where the image of the sun is projected, but to secondary processes. By “initial phase”, he means the part where the sun looks pale and well-defined, like a full moon. This isn’t something I think needs explanation (see above), but he sure has explained it. Moving on: In a second experiment, realized at 3 p.m. in December 2002, I looked straight at the sun during a much longer time. After some minutes, I saw impressive colours, up to 2 or 3 times the diameter of the sun. They changed, but were mainly pink, deep blue, red and green. Further away, the sky became progressively more luminous. I stopped there, since I understood that these colours resulted from the fact that the red, green and blue sensitive pigments are bleached and regenerated at different rates. This is frustratingly vague. Are the “impressive colors up to 2-3 times the diameter of the sun” just the normal aftereffects of staring at a bright object? Or something surprising even to physics professors? And the spinning? What about the motions of the sun? I didn’t see them, because I didn’t look at the sun for a sufficiently long time or my brain knew already too much. Once, after I had been looking at a very long passing train, I had (for about 30 seconds) the illusion of an opposite motion. Joseph Plateau discovered that when we look at the centre of a spiral that is rotating at some given velocity about this point, and when we stop this rotation, we see a reversed rotation. It lasts for several minutes, although in reality, there is no motion at all. This is a good example of motional after-effects. The “dance of the sun” is initiated, however, by a spontaneous generation of apparent motion. This feels suspiciously like a just-so story. His explanation for the sun falling to earth to crush everyone - which he also did not see - is equally ad hoc: A very interesting study was recently devoted to this “zoom and loom effect”. It tends to appear when the brain is confronted with the two-dimensional retinal image of an object that is situated at some unknown distance. The brain will then consider the possibility that it could come closer, by performing an illusory mental zoom, where the apparent size of the object is progressively increased. This results from the fact that evolution preserved the tendency to take into account the possibility of a dangerous approach: a rapid evasive action could be beneficial for survival. If true, it sounds like you should be able to generate this effect not just by staring at the sun (ill-advised, causes blindness), but by staring at the moon. I would like to test this, but unfortunately I am writing this on the night of a new moon; I’ll check back in two weeks. Still, I am skeptical that no human being living before 1917 AD ever figured out that staring at a celestial body long enough would make it appear to fall to earth and crush you. Compare to much gentler illusions - like how the moon looks bigger right when it starts to rise - which everybody knows about. I was able to find a thirdhand report (Fr. Stanley Jaki → G. J. Strangfeld → consultation with bishop) of another sun miracle investigator, one “Professor Dr. Stöckl” in Germany, who made a similar experiment: After almost a minute (the time varies according to the condition of the atmopshere and the momentary condition of the eyes) one thinks to see a dark blue disk in front of the sun (this is already a sign of the highly excited state of the retina). According to my experience … this dark blue disk is somewhat smaller than the solar disk, so that the edge of that disk stands out as a ring beyond that dark blue disk. Then one has right away the impression that the solar disk rotates with great speed in one or the other direction. This I have experienced often enough. All this is a subjective appearance that has nothing to do with the external world. These reports are suggestive, but weaker than all but the barest Fatima testimonials. Dr. Messeen admits as much, saying that “I didn’t look at the sun for a sufficiently long time”. Can we find people even more committed - or reckless, or masochistic - than Professors Messeen and Stöckl? Absolutely yes: there was a whole subfield of late 18th / early 19th century psychophysicists who experimented with staring at the sun for long periods, many of whom went blind. Joseph Plateau (1801 - 1883, went blind in 18432) summarizes their work in his aptly-named On The Contemplation Of Bright Objects. He lists twenty-six scientists who tried staring at the sun for a really long time. Most describe what we now recognize as typical retinal afterimages, and Plateau spends most of his time talking about how long these last and what colors they pass through. The only one of Plateau’s sources who reports anything even slightly interesting to us is Robert Darwin (father of Charles; cf. Secrets of the Great Families). After stating that: The author has frequently observed that when he gazed at the midday sun for a long time, until its disk appeared pale blue, he saw a bright blue specter on other objects for more than two days. …he mentions how When looking at the meridian sun as long as the eyes can well bear its brightness, the disc first becomes pale, with a luminous crescent, which seems to librate from one edge of it to the other owing to the unsteadiness of the eye. Here is pallor, and at least a hint of motion. But it’s pretty different from spinning, and not really clear how it relates to the sun miracle. Gustav Fechner (1801 - 1887, went blind in 1839) may have stared for even longer; you can read more of his story - including his ensuing insanity and subsequent attempts to found a new religion - on Adam Mastroianni’s blog. But all that he records about his ill-fated experiment is that: …after looking at the sun through homogeneously colored lenses, if you close your eyes, the primary impression remains for a long time and the entire afterimage usually disappears without a complementary coloration having clearly emerged. These people are great, and they all sound like minor Sam Kriss characters. But after whole careers dedicated to staring at the sun much longer than any normal person would ever try, they report only the barest hints of odd phenomena. Indeed, if anything they saw less of interest to the Fatimologist than Profs. Messeen and Stöckl. Worse, all of these authorities saw their phenomena after seconds to minutes of deliberate staring. Surely if it had taken a minute of staring at the sun before anything happened, some of our eyewitnesses would have mentioned this; after all, several mention that they were starting to doubt after the child-seers’ deadline had passed a few minutes earlier. But by all accounts, the miracle was near-instantaneous. Although Messeen and Stöckl’s reports of miracle-like phenomena are intriguing, it doesn’t seem like they can be the whole picture. Let’s move on. 2.2: Aurora Borealis? At This Time Of Year? In This Part Of The Country? Localized Entirely Within Your Kitchen? Could the miracle at Fatima have been some kind of weird weather phenomenon? The main argument against is that if it were a common weather phenomenon, it would not have awed and terrified tens of thousands of people. But if it were a rare weather phenomenon, then the seers’ successful prophecy that the rare weather phenomenon would happen at solar noon on October 13 1917 becomes almost as impressive as an outright miracle. The argument in favor is that dozens of people have written books and papers about this possibility, we would feel remiss if we didn’t mention them, and anyway it gives us the opportunity to look at pretty pictures of interesting weather phenomena. This is a sun dog. It’s caused by ice crystals in the upper atmosphere that refract sunlight in a very specific way. It’s very cool, but aside from a resemblance to a wheel, it looks nothing like the miracle of Fatima. A sun dog doesn’t have any unusual colors, it doesn’t change size, and it doesn’t spin (I’ve embedded a YouTube video not because a still image would be misleading - it wouldn’t be - but just in case you want to see for yourself how completely motionless it is). It’s just a halo shape with two smaller illusory suns on either side of the real one - something which no one at Fatima reported. (source) This is a solar corona3; cloud iridescence is a related phenomenon. I don’t know how much work the exposure length is doing in this particular photo, but I’m guessing more than zero. Coronae are also very pretty, and might explain the description of wheels and colors. They seem surprisingly common for something that I can’t ever remember seeing, supposedly happening several times a year in most locations. But they don’t spin, the colors don’t change or stain the surrounding landscape, and they don’t fall to earth and crush people. Let’s keep this one as a backup option and move on. This is a dust storm. Steuart Campbell wrote a paper arguing that the miracle was caused by one of these, and I admit if I saw this I would start praying pretty hard. Dust storms can change the color of the sun (including unusual colors like green or blue). And very, very charitably, whirling dust could look like the sun itself spinning around, and the thickening and thinning of dust could look like the sun approaching or receding. But this would require a dust storm localized to a 20 mile region of Portugal which does not, technically, have any dust (and where it was, technically, raining at the time). Campbell proposes that perhaps a storm blew a 20 miles x 20 mile dust cloud from the Sahara out to the Atlantic, then onto Fatima for ten minutes during a break in the rain, then back to the Atlantic again. But I don’t think any dust storm has ever behaved in quite this way. If it did, it probably wouldn’t be at the exact moment predicted by child-seers months in advance. At this point, we might as well talk about literal meteors. The way I’m imagining it is this: as a meteor approaches Earth, it breaks up into three big parts and a host of smaller particles. They strike the atmosphere head-on, from the approximate direction of the sun. The small particles hit first and make a firework show. Then the three big pieces hit, producing multicolored fireballs (meteors can absolutely stain the sky bright colors - see the video). Finally, they burn out a few miles above the ground, , convincingly producing the appearance of the sun falling to earth and nearly striking the spectators. This could even explain the warmth and dry clothes - a local meteor strike produces a lot of heat! I like this because it’s the only one that takes seriously the facet of the event which most impressed the witnesses - the part where it looked like the sun was plummeting to earth and about to kill them. But against it: would a rain of micrometeorites really look like the sun was “dancing”, “spinning”, or “zig-zagging”? Aren’t most nearby meteor strikes very loud? (the Fatima event was, according to witnesses, silent) Don’t they usually break windows? Aren’t most meteor strikes of this size visible for hundreds of miles, not just the twenty miles from which we have witness testimonies? Wouldn’t the strike have to be remarkably head-on, and remarkable close to the position of the sun, in order to look like a solar phenomenon rather than a long streak? Aren’t most meteor fireballs visible for between a few seconds and a minute, not the ten minutes of the Fatima event4? And if there were some extremely unusual meteor strike that was the exception to everything, wouldn’t it still be pretty surprising for it to happen at the exact time and place predicted by child-seers months in advance? We come to the unpromisingly-titled Derivation of equations of the model of the dynamic behavior of the three-dimensional atmospheric cloud of electrically charged ice crystals under the influence of electrostatic forces, in which Artur Wiroski argues that Fatima was a three-dimensional atmospheric cloud of electrically charged ice crystals under the influence of electrostatic forces. Actually, he offhandedly mentions Fatima in three sentences, with the majority of the paper looking more like the image above - but he eventually makes it into a Guardian article where he emphasizes that yes, he is trying to explain the miracle of the sun. However, if I’m understanding him correctly, he says that his theoretical ice crystal phenomenon can only happen when the sun is at an altitude below 22 degrees. But during the Fatima miracle, the sun was at 42 degrees (and Dalleur’s mysterious light source was at 30 degrees), so none of this applies. I’ve tried to include pictures of all the phenomena I mention in this section. I failed for this one, because it’s never been spotted or photographed. It’s just some incredibly weird thing that one scientist says ice crystals might do if parameters were ever exactly right, with such a precise definition of “exactly right” that it’s never happened in real life. If it ever did happen, it probably wouldn’t be at exactly the moment predicted by child-seers several months in advance. 2.3: Everyone’s Mad Here Except You And Me Another common response calls the Sun Miracle a “mass hallucination”. Can 70,000 people really hallucinate the same thing? “Mass hallucination” on Wikipedia redirects to List Of Mass Panic Cases. The Miracle of the Sun is on there, but listed as “(disputed)” - the only item to earn such a parenthetical. The other fifty items mostly belong to three categories: A disease with unusual symptoms spreads through a population; doctors eventually pronounce it psychosomatic.
