Lord of Eridu's Abzu, giver of the me (the powers of civilisation). He warned the flood hero (Ziusudra, Atrahasis, Utnapishtim), and in Inanna's story he gave her the me while drunk.
Where sources differ or caution applies. Enki is usually son of An, but 'Enki and Ninmah' gives Nammu as his mother and other texts vary.
Deities in other traditions who share a theme with Enki / Ea: sea and waters, wisdom, writing and divination, trickery, boundaries and travel, craft, smiths and making. This is overlap in one area only.
