The Babylonian god of war, death, and other disasters. He may be identified with Nergal, the god of death. Erra expressed death himself symbolically by his continuous lethargy as he lay in a drunken stupor. He was supplicated to ward off pestilence and other calamities. He is mentioned in one of the earliest known epic poems, written on clay tablets, called the Epic of Erra (about 1000 BCE).
