The sorceress who helps Medea and Jason wash themselves clean of the murder of Medea's brother. In a way, she is a double of Medea, who is also a sorceress. Both women are worshipers of Hecate, goddess of witchcraft, and have magical powers as a result. Medea is still young at this point in her story, however, so Circe has far more power. Circe is probably most famous for her role in Homer's Odyssey, where she captures Odysseus and attempts to keep him with her forever as her lover.
