The Erinyes live in Erebus and are more ancient than any of the Olympian deities. Their task is to hear complaints brought by mortals against the insolence of the young to the aged, of children to parents, of hosts to guests, and of householders or city councils to suppliants—and to punish such crimes by hounding culprits relentlessly. The Erinyes are crones and, depending upon authors, described as having snakes for hair, dog's heads, coal black bodies, bat's wings, and blood-shot eyes.
