and Mesopotamian thought, the world was portrayed as a disk floating in the ocean.
A similar model is found in the Homeric account from the 8th century BC in which "Okeanos, the personified body of water surrounding the circular surface of the Earth, is the begetter of all life and possibly of all gods." Scholars who believe that Hebrew cosmology came from the cosmologies of the Ancient Near Eastern cultures around them maintain that the Israelites also imagined the Earth to be a disc floating on water with an arched firmament above it that separated the Earth from the heavens.
The egg reference, however, was rather meant to clarify the relative position of the flat Earth to the heavens: In a passage of Zhang Heng's cosmogony not translated by Needham, Zhang himself says: "Heaven takes its body from the Yang, so it is round and in motion.
Earth takes its body from the Yin, so it is flat and quiescent".
This article is about cosmologies in which Earth is or was held to be flat.
For the modern misconception that medieval Europeans generally thought the Earth was flat, see Myth of the flat Earth. The flat Earth model is an archaic conception of Earth's shape as a plane or disk.
This was preconceived by the 4th-century scholar Yu Xi, who argued for the infinity of outer space surrounding the Earth and that the latter could be either square or round, in accordance to the shape of the heavens.
When Chinese geographers of the 17th century, influenced by European cartography and astronomy, showed the Earth as a sphere that could be circumnavigated by sailing around the globe, they did so with formulaic terminology previously used by Zhang Heng to describe the spherical shape of the Sun and Moon (i.e. in the 2nd century BC, Chinese astronomers effectively inverted Eratosthenes' calculation of the curvature of the Earth to calculate the height of the Sun above the Earth.
Furthermore—if that wasn’t enough—the thesis claims that the Sun has an average diameter of 1,135 kilometers and NOT 1.4 million km.
The moon has a width of 908km, and are located 687 and 23 times closer to Earth respectively.
