In Sumerian mythology, the goddess Ereskigal was queen of the Underworld. Her time of worship extended from about 3500 BC to 200 BC, or later. Her mother is Anu. By some texts she was once a sky-goddess who was abducted by the monstrous deity Kur, who was the first ever dragon. She resides in the palace of Ganzir, the doorway to Irkalla, the land of the dead. Ganzir is guarded by seven gates, each bolted and guarded by a porter. Debatably, Ereskigal may be seen as the dark alter ego of the goddess Inanna, and in some texts the elder sibling. Inanna is the Sumerian goddess of love, fertility, and warfare, and goddess of the E-Anna temple at the city of Uruk, her main centre. In legend Ereskigal is challenged by Inana but following judgment by the seven Anunnaki, the underworld goddess renders her a corpse for three days until she is revived through the intervention of Enki, the god of wisdom. In western Semitic pantheons Ereskigal becomes Allatu, an underworld goddess.
