Enki (Sumerian: 𒀭𒂗𒆠 EN-KI), also known as Ea (Akkadian: 𒀭𒂍𒀀 E₂-A) was the Mesopotamian god of wisdom, crafts, fresh subterranean waters, magic, and incantations. He was believed to rule the Abzû. In Mesopotamian astronomy, he was associated with the stars of the southern band of the sky. Enki’s wife was Damgalnuna, and their children included Nanshe, Asalluhi, Marduk and Enbilulu. His sukkal (attendant deity) was Isimud. Servants of the god included lahmu, kulullû, and the Seven Sages.
Enki was first worshipped by the Sumerians of Southern Mesopotamia. The earliest sources associate him with the city of Eridu, which was his main cult center, and regarded as his home. His temple there was the E-Abzû. Enki was already a major deity in Sumer at the time of the earliest written sources, and the influence of his cult spread outside of Southern Mesopotamia early on. It is uncertain when Enki was assimilated to Ea, a god whose name is of unknown, but possibly semitic origin. Under the name Ea, Enki was worshipped by the Akkadians, Babylonians and Assyrians. His cult was particularly influential in the Ur III and Old Babylonian Periods, where he became part of a triad at the top of the pantheon consisting of Anu, Enlil and himself. He was incorporated into Hurrian religion as a major god, with identical character and functions as in Mesopotamia. His cult spread into Anatolia, possibly as early as the third millennium BCE, and he became part of the Hittite pantheon. With the rise of Babylon and its patron god Marduk, Ea’s cult gradually lost importance, though he still remained a major god in first millennium BCE Mesopotamia.
