The shape of the earth

People held different beliefs about the shape of the earth throughout history. Even today some remnants of disagreement against the prevailing theory that it is basically spherical spark passionate discussion among those inclined to listen.

The belief that the earth is shaped like a flat disc arose in ancient times, perhaps because of the apparently flat nature of the ground and the apparently circular nature of horizon in the distance. The belief that the earth is shaped like a sphere arose in ancient Greece and gradually supplanted it.

Often the basic shape of the earth was just one component of a larger cosmological model, and was integrated tightly with mythology and religion. Unfortunately for purposes of argument mapping, even the direction of the inference, whether from myth to shape or from shape to myth, is sometimes unclear.
