The Graeae were three sisters in Greek mythology, who shared one eye and one tooth among them. Their names were Deino (dread), Enyo (horror) and Pemphredo (alarm). They were the daughters of the sea gods Phorcys and Ceto, and sisters of the Gorgons. They took turns using their eye and their tooth. Their age was so great that a human childhood for them was hardly conceivable.
