Ancient Beliefs That Were Wrong

Beliefs from before 500 CE, when the best available science was a confident guess.

The ancient world built the pyramids, mapped the stars, and worked out the circumference of the Earth to within a few percent. It also drilled holes in living skulls to release evil spirits, balanced the body's four humours with leeches, and was confident the heart did the thinking while the brain just cooled the blood. You would have believed all of it too. The evidence available to a clever person in 400 BCE pointed exactly that way. What is striking is not that they were wrong, but how reasonable the wrong answers looked at the time. Most of these beliefs outlived the civilisations that invented them, passed down for thousands of years because nobody had a better idea yet.
