Tisiphone
One of the Eumenides (Furies) from Graeco-Roman tradition. Tisiphone, whose name means retaliation, was the avenger of murder. She sat at night at the entrance to hell armed with a whip with which she inflicted cruel punishments on criminals. She wore a bloody robe and had serpents instead of hair.
