The Greek Furies, these ladies are not to be messed with! Even Zeus himself can do nothing to stop them from punishing the wicked and any unnatural act. They avenged crimes, driving their victims mad as they pursued them. Among those they tortured were Orestes, Oedipus, Meleager, and Agamemnon.
The Furies are also sometimes ironically known as the Eumenides, or "the kindly ones".
