Damu was a Mesopotamian god. While originally regarded as a dying god connected to vegetation, similar to Dumuzi or Ningishzida, with time he acquired the traits of a god of healing. He was regarded as the son of the medicine goddess Ninisina, or of her equivalents such as Gula or Ninkarrak. It is unclear which city was originally associated with him, but he is best attested in association with the cult center of his mother, Isin.

Ningishzida was a Mesopotamian deity of vegetation, the underworld and sometimes war. He was commonly associated with snakes. Like Dumuzi, he was believed to spend a part of the year in the land of the dead. He also shared many of his functions with his father Ninazu.
