Enki

Enki (/ˈɛŋki/; Sumerian: dEN.KI(G)𒂗𒆠) is the Sumerian god of water, knowledge (gestú), mischief, crafts (gašam), and creation (nudimmud), and one of the Anunnaki. He was later known as Ea in Akkadian and Babylonian mythology. He was originally patron god of the city of Eridu, but later the influence of his cult spread throughout Mesopotamia and to the Canaanites, Hittites and Hurrians. He was associated with the southern band of constellations called stars of Ea, but also with the constellation AŠ-IKU, the Field (Square of Pegasus). Beginning around the second millennium BCE, he was sometimes referred to in writing by the numeric ideogram for "40", occasionally referred to as his "sacred number". The planet Mercury, associated with Babylonian Nabu (the son of Marduk) was, in Sumerian times, identified with Enki.

Many myths about Enki have been collected from various sites, stretching from Southern Iraq to the Levantine coast. He is mentioned in the earliest extant cuneiform inscriptions throughout the region and was prominent from the third millennium down to Hellenistic times.

The exact meaning of his name is uncertain: the common translation is "Lord of the Earth". The Sumerian En is translated as a title equivalent to "lord" and was originally a title given to the High Priest. Ki means "earth", but there are theories that ki in this name has another origin, possibly kig of unknown meaning, or kur meaning "mound". The name Ea is allegedly Hurrian in origin while others  claim that his name 'Ea' is possibly of Semitic origin and may be a derivation from the West-Semitic root *hyy meaning "life" in this case used for "spring", "running water". In Sumerian E-A means "the house of water", and it has been suggested that this was originally the name for the shrine to the god at Eridu. It has also been suggested that the original non-anthropomorphic divinity at Eridu was not Enki but Abzu. The emergence of Enki as the divine lover of Ninhursag, and the divine battle between the younger Igigi divinities and Abzu, saw the Abzu, the underground waters of the Aquifer, becoming the place in which the foundations of the temple were built. With some Sumerian deity names as Enlil there are variations like Elil. En means "Lord" and E means "temple". It is likely that E-A is the Sumerian short form for "Lord of Water", as Enki is a god of water. Ab in Abzu also means water.
