 One of her more gruesome feats in the epic is to drive the hero, Tydeus, to cannibalism.In a bizarrely pastoral scene, Tisiphone first appears in the epic lounging beside the Cocytus river in the underworld, letting her serpent locks lap at the sulfuric waters.According to one myth, she fell in love with a mortal, Cithaeron, but was spurned; in her anger she formed a poisonous snake from her hair, which bit and killed him.
