According to Greek mythology, Erinyes were female chthonic deities of vengeance; they were sometimes referred to as "infernal goddessess". A formulaic oath in the Iliad says that "those who beneath the earth punish whosoever has sworn a false oath. They correspond to the Furies or Dirae in Roman mythology.
The Erinyes live in Erebus and are more ancient deities than any of the Olympians. 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, are described as having snakes for hair, dog's heads, coal black bodies, bat's wings, and blood-shot eyes. In their hands they carry brass-studded scourges, and their victims die in torment.
