In Ancient Greek mythology, Maniae or Mania (Ancient Greek: Μανίαι/Μανία, romanized: Maniae/Mania) are the spirits personifying insanity, madness, and crazed frenzy. They operate closely with Lyssa, the spirit of rage and rabies, and like Lyssa, are presumed to be daughters of Nyx. They are also associated with the Erinyes, the three fearsome goddesses of vengeance.
They are also sometimes said (though, perhaps in jest, or as a metaphor for love's sometimes cruel nature) to have been nurses of the god Eros.
