What is "ninazu"

Ninazu in Sumerian mythology was a god of the underworld, and of healing. He was the son of Enlil and Ninlil or, in alternative traditions, of Ereshkigal and Gugalana, and was the father of Ningiszida. In the text Enki and Ninhursag he was described as the consort of Ninsutu, one of the deities born to relieve the illness of Enki.

Ninazu was the patron deity of the city of Eshnunna until he was superseded by Tispak. He had sanctuaries were the E-sikul and E-kurma. Unlike his close relative Nergal, he was generally benevolent.
