When Was It Discovered the Earth Is Not Flat?

Answer

The exact year when it was discovered that the earth was not flat, but rather spherical, is not clearly documented. What is clear, however, is hat it was around the 6th century, BC, and displaced earlier thoughts of the earth being flat. However, there was still a lot of speculation such that the idea of the spherical earth was not adopted until the 3th century BC, as a physical given by the Hellenistic astronomy.
