How the peoples of the ancient Near East pictured the world: a flat earth under a solid vault, with waters above and below. This page presents that geocentric understanding as it appears in the surviving texts and art, not as a modern scientific claim.

The picture reconstructed here is drawn from the literature and iconography of Mesopotamia, Egypt, and the Hebrew Bible, roughly the second and first millennia BCE. It is not a single official doctrine but a shared set of assumptions visible across those cultures.
These texts describe how the world was ordered and maintained. They do not present a modern heliocentric or evolutionary account of planetary formation.
In the common ancient Near Eastern picture the cosmos is a series of stacked regions, all centered on the inhabited earth.
The whole arrangement is static and centered on the human world. There is no empty outer space and no orbiting planets in the later Greek sense.
“Geocentric” here means the inhabited earth is the fixed center of the ordered world. The lights in the sky move around or across it; the earth does not move.
This is not yet the later Greek mathematical geocentrism of epicycles and deferents. It is a cosmological picture in which:
When Greek astronomers later calculated planetary positions with circles, they still placed the earth at or near the center. The ancient Eastern picture supplied the basic orientation—earth fixed, heavens moving—that those calculations refined.
After defeating Tiamat, Marduk splits her body “like a shellfish.” One half he sets up as the sky, the other becomes the earth. He assigns stations to the gods, fixes the year, and establishes the paths of the celestial bodies. The ordered world is the result of a divine victory over watery chaos.
The account begins with the earth formless and the deep covered in darkness. God speaks a firmament into the midst of the waters, separates the waters above from the waters below, and names the firmament “heaven.” On the second day the dry land appears; on the fourth the lights are set in the firmament to rule day and night and to mark seasons. The structure matches the wider Near Eastern layered cosmos, while the agent and the evaluation (“it was good”) are distinctive to the Hebrew text.
Nut, the sky, is shown as a woman arched on hands and feet over Geb, the earth. The sun travels through her or sails in a boat. The picture is anthropomorphic, yet the geometry is the same: a covering sky over a stable earth, with waters at the edges.
Greek natural philosophers from the sixth century BCE onward proposed that the earth is a sphere and that the heavens are concentric spheres. By the second century BCE, Hipparchus and others were calculating lunar and solar positions with eccentric circles. Ptolemy’s Almagest (second century CE) gave a full geocentric system of deferents, epicycles, and the equant that could predict planetary positions for centuries.
That mathematical geocentrism is a different achievement from the ancient Eastern layered cosmos, but it preserves the same central commitment: the earth does not move, and the lights of heaven travel around it. The shift to a moving earth came much later, with Copernicus, Kepler, and Galileo.
