Nammu was a Mesopotamian goddess regarded as a creator deity in the local theology of Eridu. It is assumed that she was associated with water. She is also well attested in connection with incantations and apotropaic magic. She was regarded as the mother of Enki, and in a single inscription she appears as the wife of Anu, but it is assumed that she usually was not believed to have a spouse.

Enki is the Sumerian god of water, knowledge (gestú), crafts (gašam), and creation (nudimmud), and one of the Anunnaki. He was later known as Ea or Ae in Akkadian (Assyrian-Babylonian) religion, and is identified by some scholars with Ia in Canaanite religion. The name was rendered Aos in Greek sources.
