By most accounts, she was the daughter of Helios, the god of the Sun, and Perse, one of the three thousand Oceanid nymphs. Her brothers were Aeëtes, keeper of the Golden Fleece and father of Medea, and Perses. Her sister was Pasiphaë, the wife of King Minos and mother of the Minotaur. Other accounts make her the daughter of Hecate, the goddess of witchcraft by Aeëtes, usually said to be her brother instead. She was often confused with Calypso, due to her shifts in behavior and personality, and the association that both of them had with Odysseus.
