Lyssa

In Greek mythology, Lyssa (/ˈlɪsə/; Ancient Greek: Λύσσα Lússā), called Lytta (/ˈlɪtə/; Λύττα Lúttā) by the Athenians, was the spirit of mad rage, frenzy, and rabies in animals. She was closely related to the Maniae, the spirits of madness and insanity. Her Roman equivalent was variously named Ira, Furor, or Rabies. Sometimes she was multiplied into a host of Irae and Furores.
