II. THE FIRST CIVILISATIONS — c.3000 – 1000 BCE
How many
None. Absorbed into Akkadian and Babylonian religion.
Who began it
No founder. Institutional religion here is essentially an accounting technology that grew into a theology: the temple was the city's granary, workshop and bank before it was anything else, and the earliest writing on earth is temple inventory.
What it is for
Humanity was created to work so the gods would not have to. The purpose of religion was to keep the gods fed, housed and content, because the alternative was flood, plague and the collapse of the irrigation system everyone lived on.
What it worships
A pantheon of several hundred, headed by An (sky), Enlil (air and command), Enki/Ea (fresh water, craft and cunning), Inanna (love, war, Venus), Utu (sun and justice), Nanna (moon). Each city belonged to a god and the god literally lived in the temple statue, which was washed, dressed, fed twice daily and taken travelling.
What it holds
The gods hold the me — the fixed decrees and offices that make civilisation work, from kingship and the priesthood down to prostitution and the art of the scribe. Kings rule by divine appointment and the Sumerian King List asserts that kingship itself descended from heaven. Human beings were formed from clay mixed with divine blood.
What it does
The ziggurat, a stepped platform raising the god's house above the plain. Daily feeding of the cult statue. New Year akitu festival. Sacred marriage rite in which the king ritually married Inanna, probably enacted with a priestess. Extispicy — reading the liver of a sacrificed sheep — as the standard method of divination, later exported as far as Etruria.
After death
Uniformly bleak. All the dead, good and bad alike, descend to Kur or Irkalla, the house of dust, where they eat clay and dust and are clothed like birds in feathers. There is no reward and no punishment. The one thing that matters is having descendants to pour water for you; the unmourned dead are the worst off. Compare this to the Egyptian afterlife of the same era and the contrast is total.
Its texts
Descent of Inanna; the Sumerian Gilgamesh poems that later became the Epic of Gilgamesh, the oldest long poem in the world, whose subject is the refusal to accept death; temple hymns of Enheduanna, priestess of Ur and daughter of Sargon, the first author in history whose name we know.
Its branches
Continued directly as Akkadian, Babylonian and Assyrian religion.
Of note
The flood narrative here — a god warns one man, he builds a boat, sends out birds, the boat grounds on a mountain — predates the Genesis account by well over a thousand years and the literary dependence is accepted by nearly all specialists.
Its timeline
- c.4000 BCE Temple platforms at Eridu, the city the Sumerians themselves named as the first.
- c.3200 BCE Proto-cuneiform on clay tablets at Uruk — invented to track temple offerings.
- c.2334–2279 BCE Sargon of Akkad installs his daughter Enheduanna as high priestess; her hymns fuse Sumerian and Akkadian gods to unify the empire.
- c.2100 BCE The great ziggurat of Ur built under Ur-Nammu.
- c.2100 BCE Separate Sumerian poems about Gilgamesh are in circulation.
- 18th c. BCE The Old Babylonian Epic of Gilgamesh joins them into a single Akkadian narrative. The Standard version by Sîn-lēqi-unninni follows around 1200 BCE.
- c.1750 BCE Sumerian dies as a spoken language; the religion continues in Akkadian dress.
