Enki was a deity in Sumerian mythology, later known as Ea in Babylonian mythology. The name Ea is of Sumerian origin and was written by means of two signs signifying "house" and "water". Enki was the deity of water, intelligence and creation. The main temple of Enki was the so-called é-engur-ra, the "house of the (water-)deep"; it was in Eridu, which was in the wetlands of the Euphrates valley at some distance from the Persian Gulf. He was the keeper of the holy powers called Me. The exact meaning of his name is not sure: the common translation is "Lord of the Earth": the Sumerian en is translated as "lord", ki as "earth"; but there are theories that ki in this name has another origin.He is the lord of the Apsu, the watery abyss. His name is possibly an epithet bestowed on him for the creation of the first man, [Adamu or Adapa. His symbols included a goat and a fish, which later combined into a single beast, the Capricorn, which became one of the signs of the zodiac. Enki had a penchant for beer and a string of incestuous affairs. First, he and his consort Ninhursag had a daughter Ninsar. He then had intercourse with Ninsar who gave birth to Ninkurra. Finally, he had intercourse with Ninkurra, who gave birth to Uttu.
