In Mesopotamian mythology, Ereshkigal was the goddess of Kur, the land of the dead or underworld in Sumerian mythology. In later myths, she was said to rule Irkalla alongside her husband Nergal. 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. "Lady of the Great Earth".

Inanna is the ancient Mesopotamian goddess of love, war, and fertility. She is also associated with sensuality, procreation, divine law, and political power. Originally worshiped in Sumer, she was known by the Akkadian Empire, Babylonians, and Assyrians as Ishtar. Her primary title was "the Queen of Heaven".
