Medea was the daughter of Aeëtes, king of Colchis, and Eidyia. She was the priestess of the Underworld goddess, Hecate, and had the power to work miracles for good or evil (like her aunt Circe). Her name undoubtedly means 'cunning' (medea), and this interpretation accords well with that for her mother (see Eidyia).
