Why Was Aristarchos’s Heliocentric Model Dismissed and Ignored?

Many people are astonished to learn that the concept of heliocentrism did not originate with Nicolaus Copernicus, but rather with the ancient Greek astronomer Aristarchos of Samos (lived c. 310 – c. 230 BC), who published a book in around the early third century BC in which he argued that the Earth orbits around the Sun. This book has not survived, but we know about its existence because it is referenced by later authors.

What shocks many people even more than the fact that Aristarchos came up with the idea of heliocentrism in the third century BC is the fact that Aristarchos’s heliocentric model of the universe was almost totally rejected by ancient Greek and Roman scholars and never caught on in antiquity. Many people wonder why it was that the ancient Greeks never took Aristarchos seriously. In order to find out why Aristarchos’s heliocentric model of the universe was rejected, we are going to need to dive deep into the ancient sources.

The Truth about the Archimedes Palimpsest

If you have an interest in ancient science or mathematics, chances are you have probably heard at some point about the Archimedes Palimpsest. According to the narrative that New Atheist writers and media outlets keep pushing, the ancient Greek mathematician Archimedes of Syracuse (lived c. 287 – c. 212 BC) wrote groundbreaking mathematical treatises that were millennia ahead of their time.

Then, according to the standard narrative being pushed, in the thirteenth century AD, ignorant, obscurantist Christians who did not care about science or mathematics erased the text of the manuscript containing the last known copies of several of Archimedes’s treatises and reused the parchment to make a prayer book. Now—or so the story goes—Archimedes’s previously lost groundbreaking works are being recovered through the brilliancy of modern secular technology.

Unfortunately, this narrative that I have just outlined is deeply, deeply misrepresentative and based on an extremely selective presentation of the evidence. If the media would tell the full story of the Archimedes Palimpsest, we would be getting a very different narrative—a narrative not about how religion is inherently dangerous and destructive, but rather a far more complex narrative in which religious individuals are neither inherently evil nor inherently good but simply human beings capable of both good and evil.

Were the Greeks Really Obsessed with the Golden Ratio?

The so-called “Golden Ratio,” or φ, occurs when the ratio of the greater of two quantities to the lesser of two quantities is equivalent to the ratio of the sum of the two quantities to the greater of the two quantities. Expressed using incomprehensible math symbols, it looks like this:

Many people believe that the “Golden Ratio” is the pinnacle of aesthetic perfection and that, the closer something is to the Golden Ratio, the more beautiful it is automatically. Many people also believe that the ancient Greeks were obsessed with the Golden Ratio and that they incorporated it into all their buildings and works of art. Unfortunately for those who love a good math story, we have no good evidence to support either of these conclusions.

In fact, the Golden Ratio is not even mentioned in any Greek text until as late as the early third century BC. The Greeks were arguably fascinated with the idea of using mathematical proportions in art to a certain extent, but they were by no means obsessed with the Golden Ratio in particular. The story of how we came to believe that the Greeks were obsessed with the Golden Ratio, though, is as fascinating as it is bizarre. It involves a friend of Leonardo da Vinci, an eccentric nineteenth-century German psychologist, and Donald Duck.

Was Hypatia of Alexandria Black?

A lot of people today seem to have quite a fascination with the subject of race in the ancient world. I frequently encounter questions on Quora asking whether various historical figures from ancient times were “Black” or “white.” Elsewhere online, I often encounter claims about the racial identities of people from ancient times.

Back in September 2019, I wrote an article in response to various articles I had encountered claiming that the Roman emperor Septimius Severus was Black. In that article, I concluded that, while you could certainly describe Septimius Severus as what we today would call a “person of color,” it would be misleading to describe him as Black without any kind of careful qualification.

Another historical figure from ancient times whose racial identity seems to provoke a great deal of controversy is the early fifth-century AD Neoplatonist philosopher and mathematician Hypatia of Alexandria, who is often cited (quite anachronistically) as an example of a Black woman who excelled in STEM. In this article, I will answer the question: “Was Hypatia of Alexandria really Black?”

What Evidence Is There for Atheism in Ancient Greece?

A frequent question I have encountered is the question of whether there were atheists in ancient Greece. This is a question that is surprisingly difficult to answer and I think the most appropriate answer is something along the lines of “sort of, but not exactly.” Although it is certainly possible that there were people in ancient Greece who rejected the existence of all deities, the historical evidence for the existence of such individuals is extremely limited to say the very least.

We have solid evidence for the existence of people in ancient Greece who criticized certain aspects of traditional Greek religion and we even have solid evidence for the existence of people in ancient Greece who might be termed “agnostics,” but we have no clear, unambiguous, contemporary historical evidence for the existence of people in ancient Greece who outright denied the existence of all deities altogether.

Misconceptions about the Library of Alexandria

The Great Library of Alexandria is by far the most famous library that existed in the ancient world. At its height in the third century BC, it attracted renowned scholars from all over the Hellenistic world. It is likely that it held more scrolls than any other library in the Mediterranean at the time. Many people today see this library as a symbol of everything the ancient world accomplished.

As a result of the Great Library’s fame, however, it has become heavily mythologized. Many of the things that many people today believe about the library are simply not true. For instance, contrary to what you may have read on the internet, the Library of Alexandria was not the first library ever built, its famous destruction is not the primary reason why so many texts from ancient times have been lost, and it was certainly not deliberately destroyed by religious obscurantists of any kind.

Could You Have Survived in the Ancient World?

At some point, many people have wondered, “Could I have survived to a ripe old age if I had been born 2,000 years ago?” If you have ever wondered this, you are in luck, because right now is your chance to find out! In this article, we are going to be exploring some of the most common things that killed people in antiquity at different stages of their lives. We are also going to talk about how, believe it or not, some people in ancient times actually managed to survive to quite impressively old ages, even by twenty-first century standards.

“Archimedes’s Death Ray” Debunked

Most people with an interest in the history of science have heard the famous story of “Archimedes’s death ray.” In case you are unfamiliar with it, it goes like this: Supposedly, during the Siege of the Greek city of Syracuse by the Romans, lasting from spring of 213 BC through autumn of 212 BC, the brilliant Syracusan inventor and mathematician Archimedes (lived c. 287 – c. 212 BC) developed a spectacular invention to keep the Roman ships at bay; he built a death ray using mirrors to concentrate the light of the sun on the Roman ships, thereby setting them on fire. Unfortunately for all the people out there who love a good story about a brilliant inventor fending off enemy forces using science, the story of “Archimedes’s death ray” is certainly apocryphal.

Who Was Hypatia of Alexandria Really?

Alongside the venerable ranks of Cleopatra, Boudicca, and Olympias, the philosopher Hypatia of Alexandria (lived c. 350 x c. 375 – 415 AD) is one of the single most famous historical women of classical antiquity. Unfortunately, there is a tremendous amount of misinformation about her out there and, if you have read about her previously, there is a very high probability that the vast majority of what you have read about her is fiction. Join as we discover the real Hypatia of history, as well as how the myths surrounding her have accrued over the years.

No, Atlas Did Not Hold the Earth on His Shoulders

The image of the Titan Atlas holding the Earth on his shoulders is an iconic one that has inspired countless writers, thinkers, and artists. It is also a modern notion with no basis whatsoever in any ancient Greek texts. In actual ancient Greek mythology, Atlas does not, in fact, hold the Earth on his shoulders, but rather the sky. The misconception that the ancient Greeks imagined Atlas as holding the Earth on his shoulders arose as a result of the misinterpretation of classical representations of Atlas. In this article, I intend to set the record straight by examining how the ancient Greeks really envisioned Atlas and explaining how the misconception about him holding up the Earth arose.
