Nergal, Mesopotamian (Sumerian and Babylonian-Akkadian) [Iraq}, was a chthonic underworld god, worshipped from c. 3500 BC to 200 BC. His centers of worship were Kuthu and Tarbisu. He was the son of Enlil and Ninlil and the consort of the underworld goddess Ereskigal. He is depicted as the god of war and sudden death as well as the Emeslam. He is usually shown as a bearded figure emerging from the ground carrying a double-edged mace-scimitar typically embellished with lion heads. By the Hellenic period he is identified with the god Hercules. A.G.H.
