Kamikaze Tisiphone

In Greek mythology the Erinyes or Eumenides (the Romans called them the Furies) were female personifications of vengeance. Their number is usually left indeterminate, though Virgil recognized three: Alecto ("unceasing"), Megaera ("grudging"), and Tisiphone ("avenging murder").

They were usually said to have been born from the blood of Uranus when Cronus castrated him. According to a variant account, they issued from an even more primordial level—from Nyx, "Night". They were understood as the persecutors of mortal men and women who broke "natural" laws. In particular, those who broke ties of kinship through patricide, murdering a brother, or other such familial killings brought special attention from the Erinyes.

It was believed in early epochs that human beings might not have the right to punish such crimes, instead leaving the matter to the dead man's Erinyes to exact retribution. The Erinyes were connected with Nemesis as enforcers of a just balance in human affairs. When not stalking victims on Earth, the Furies were thought to dwell in Tartarus, where they applied their tortures to the damned souls there.

Many scholars believe that when they were originally referred to as the Eumenides it was not to reference
their good sides but as a uphemism to avoid their wrath that would ensue from calling them by their true name. This taboo on speaking the names of certain uncanny spirits included Persephone; there are parallels in many cultures. The Erinyes might also be recognized as Semnai ("the venerable ones"), the Potniae ("the Awful Ones"), the Maniae ("the Madnesses") and the Praxidikae ("the Vengeful Ones").

The Furies (their Roman name) or Dirae ("the terrible") typically had the effect of driving their victims insane,
hence their Latin name furor.
