Erinyes

"Tisiphone was one of the Erinyes or Furies, and sister of Alecto and Megaera. She was the one who punished crimes of murder: parricide, fratricide and homicide. A myth recounts how Tisiphone fell in love with Cithaeron, and caused his death by snakebite, specifically, by one of the snakes from her head. In Book VI of Virgil's Aeneid, Tisiphone is recognized as the furious and cruel guardian of the gates of Tartarus"
