In Mesopotamian mythology, Ereshkigal ( , lit. "Queen of the Great Earth") was the goddess of Irkalla, the land of the dead or underworld. Sometimes her name is given as Irkalla, similar to the way the name Hades was used in Greek mythology for both the underworld and its ruler, and sometimes it is given as Ninkigal, lit. "Great Lady of the Earth" or "Lady of the Great Earth".
