The myth of the Medieval Flat earth belief

The myth that a flat earth was part of Christian doctrine in the Middle Ages appears to have originated with Sir Francis Bacon (1561-1626), who wrongly claimed that geographers had been put on trial for impiety after asserting the contrary. There were a few authentic flatearthers in late antiquity, but none among the scholars of the Middle Ages proper.
