A small curiosity that I found on Columbus Day. Most people of Columbus' day did not believe the world was flat.
Which is quite different from the rhetorical cudgel that gets used these days when one dissents from a majority point of view.Historians say there is no doubt that the educated in Columbus’s day knew quite well that the Earth was not flat but round. In fact, this was known many centuries earlier.As early as the sixth century B.C., Pythagoras — and later Aristotle and Euclid — wrote about the Earth as a sphere. Ptolemy wrote “Geography” at the height of the Roman Empire, 1,300 years before Columbus sailed, and considered the idea of a round planet as fact.“Geography” became a standard reference, and Columbus himself owned a copy. For him, the big question was not the shape of the Earth but the size of the ocean he wanted to cross.
