Sumerian gods
The myths of the Sumerian gods are the oldest human myths about the gods, their worlds, tasks, powers, and degrees. Each city of ancient Sumer since the fourth millennium BC was designated by specific gods, who had their own temples, rituals, and those responsible for them, including priests, priestesses, and less. After the disappearance of the Sumerians, these gods remained an independent political entity, and were inherited by the Akkadians, Babylonians, and Assyrians. The names of some of them were changed or multiplied, other tasks were modified, and gods advanced and others declined.
There are also many texts about them, including epics and hymns, and what this abundance imposes is the variation in the name and its pronunciation, and the change in the relationship between one god and another, or one god and his consort. From all of this comes an abundance of information that makes it impossible to determine a fixed group for these gods. In the diagram below, the complex of Sumerian gods is based on the majority of the relationships mentioned between the gods in the Sumerian texts.
