The Graeae were the three sisters of the Gorgons (notably Medusa). They had but one eye and one tooth among them. These were shared and the sisters took turns in using them. By stealing their eye while they were passing it between them, Perseus forced them to tell the whereabouts of their sister, Medusa, ransoming the seeing eye for the information. The lead Graeae, sight returned, mocks Perseus and laughingly calls out to her sister Medusa to warn of his coming.
