Most tales mention three Furies: Allecto (endless), Tisiphone (punishment), and Megaera (jealous rage). Usually imagined as monstrous, foul-smelling hags, the sisters had bats' wings, coal-black skin, and hair entwined with serpents. They carried torches, whips, and cups of venom with which to torment wrongdoers. The Furies could also appear as storm clouds or swarms of insects.
