The Cosmic Sea
Babylonian / Enūma Eliš
The world is the body of a slain goddess; the sky is held back water, the Earth her corpse. Order is a victory of gods over chaos, renewed by ritual. The cosmos has a biography, not a mechanism.
SYSTEM 08 / COSMOLOGY & UNIVERSE MODELS
Two ways to hold the sky
Every culture builds a cosmos. The question is what kind of object it is. A mythic cosmos has a biography — a story of gods and battles. A rational cosmos has a mechanism — a structure of causes you could, in principle, be wrong about. Watch the same sky pass from one to the other.
MYTHIC COSMOS
Nut & Geb
Egyptian cosmogony
The sky-goddess Nut arches over the earth-god Geb; the sun is sailed across her body each day in a boat. Regularity is divine routine — reliable because a god is faithful, not because a law is binding.
RATIONAL COSMOS
Earth on Water
Thales
The Earth floats on water like a log; earthquakes are the sloshing of that sea, not a god's anger. The explanation is still wrong, but it is the first to be physical — a cause you could, in principle, check.
The Suspended Earth
Anaximander
A cylindrical Earth hangs unsupported at the centre, equidistant from everything and so with no reason to fall. The heavenly bodies are rings of fire seen through holes. The first cosmos governed by symmetry and proportion.
Cosmos of Compressed Air
Anaximenes
Earth and the heavenly bodies ride on air; the stars are fixed like nails in a crystalline vault, condensed from the same air as everything else. One substance, one process, one cosmos — a unified physics of the sky.
08.G
ANAXIMANDER'S COSMOS · GOVERNED BY SYMMETRY
The first cosmos that needs no support and no story. The Earth stays put because it is equidistant from everything — it has no reason to move in any direction. Reason, not myth, holds up the world.
