The Israelites had a similar cosmology, with the earth as a flat disc floating on water beneath an arced firmament separating it from the heavens. Ancient Hindu, Jain, and Buddhist cosmology held that the Earth is a disc consisting of four continents grouped around a central mountain (Mount Meru) like the petals of a flower.
