History sometimes claims that Columbus was the one to discover that the world was not flat but rather round. Wrong!, Copernic (polish), Gallileo (italian) and many other scientists claimed that theory in the earlier 14th & 15th centuries. Columbus was just the first one to act upon it (gutsy enough). And the "round-world" theory was confirmed rather, not by Columbus, but by Magellan (Portuguese), who was the first one to sail around the world in the mid1500's (16th century)

The Greeks and Phoenicians knew it at least 2300 years ago. The Greeks performed a very clever experiment which not only proved it but gave an accurate measurement of its circumference. Then a few centuries later a Christian mob burned the library containing this information. It was another 1000 years before Europeans rediscovered it. Again the Christian church tried to suppress the information. Galileo's book about it wasn't removed from the Catholic Church's proscribed list until, wait for it, 1992.

The earth is not round. It is an oblate spheroid, The distance around the equator is not the same as the great circle that passes through the poles.
A better question would have been, when was it discovered that the earth was not flat?

The Earth had always been considered round.
Leaders and Religious powers of the Middle Ages believed it to be flat though all proof even at that time proved a round Earth.
You were a Heretic if you went against the Religious and Rulers.

There were a couple of independent occurrences. The greeks (Pythagoras) knew, then Europe kind of "rediscovered" it. So it's hard to say.
