Ninazu

Ninazu (Sumerian: 𒀭𒊩𒌆𒀀𒋢) was a Mesopotamian god of the underworld of Sumerian origin. He was also associated with snakes and vegetation, and with time acquired the character of a warrior god. He was frequently associated with Ereshkigal, either as a son, husband, or simply as a deity belonging to the same category of underworld gods.

His original cult centers were Enegi and Eshnunna, though in the later city he was gradually replaced by a similar god, Tishpak. His cult declined after the Old Babylonian period, though in the city of Ur, where it was introduced from Enegi, he retained a number of worshipers even after the fall of the last Mesopotamian empires.
