We have some idea of the evolution of the Babylonian view of the Earth and its approximate dimensions/shape: https://en.wikipedia.org/wiki/Babylonian_Map_of_the_World https://en.wikipedia.org/wiki/Babylonian_Map_of_the_World This idea probably wasn't unique to the Babylonians, but this approximation of a disc-shaped Earth was fairly commonplace up to and including the Exhilic Period (biblical texts likely being influenced, at least in part, by the Babylonian views though much of the text is certainly constructed of polemic narratives).
