In Greek mythology, Mania ("insanity") was the personification of insanity.
In Roman mythology, Mania was the goddess of the dead. She, along with Mantus, ruled the underworld. She was said to be the mother of ghosts, the undead and other spirits of the night, as well as the Lares and the Manes. Mania was borrowed from the Etruscan goddess Manea after the assimilation of the Etruscan people by the Romans.
