Ea, Mesopotamian god of water and a member of the triad of deities completed by Anu (Sumerian: An) and Enlil. Ea is considered a member of the special class of Mesopotamian gods called the Anunnaki.
From a local deity worshiped in the city of Eridu, Ea evolved into a major god, Lord of Apsu (also spelled Abzu), the fresh waters beneath the earth (although Enki means literally “lord of the earth”). In the Sumerian myth “Enki and the World Order,” Enki is said to have fixed national boundaries and assigned gods their roles. According to another Sumerian myth Enki is the creator, having devised men as slaves to the gods. In his original form, as Enki, he was associated with semen and amniotic fluid, and therefore with fertility. He was commonly represented as a half-goat, half-fish creature, from which the modern astrological figure for Capricorn is derived.
Ea, the Akkadian counterpart of Enki, was the god of ritual purification: ritual cleansing waters were called “Ea’s water.” Ea governed the arts of sorcery and incantation. In some stories he was also the form-giving god, and thus the patron of craftsmen and artists; he was known as the bearer of culture. In his role as adviser to the king, Ea was a wise god although not a forceful one. In Akkadian myth, as Ea’s character evolves, he appears frequently as a clever mediator who could be devious and cunning. He is also significant in Akkadian mythology as the father of Marduk, the national god of Babylonia.
