What shape did medieval people believe the earth was?
Wrong. Since around the fourth century BC, almost no-one, anywhere has believed the earth to be flat. This misconception that people where ignorant of the shape of the earth comes from the partially fictional text ‘The Life And Voyages Of Christopher Columbus’ (1828), which incorrectly stated that Columbus set out to prove the earth was round. Truth is, nobody would have disputed the theory. Evidence shows that almost all cultures of the world worked out, through mathematics or just observation, the spherical nature of the Earth.
