The daughter of Zeus and Demeter, who was carried off while gathering flowers by Pluto (q. v .), became Queen of Hades, and is represented as sitting on an ebony throne beside him wearing a crown. According to later tradition Pluto had to allow her to revisit the upper world for two-thirds of the year to compromise matters with her mother, her arrival being coincident with the beginning of spring and her return to Hades coincident with the beginning of winter. She became by Pluto the mother of the Furies.
