So much of what we say about Columbus is either wholly untrue or greatly exaggerated. Here are a few of the top offenders. 1. Columbus set out to prove the world was round. If he did, he was about 2,000 years too late. Ancient Greek mathematicians had already proven that the Earth was round, not flat. Pythagoras in the sixth century B.C.E. was one of the originators of the idea.
But they donât. This is because the earth is round, and not flat: Eratosthenes (276-194 BCE) used this principle to calculate the circumference of the Earth quite accurately. To see this demonstrated, refer to my experiment video about Eratosthenes and the circumference of the earth â âThe Earthâs curvature is tasty!â.
