MANES, in the Pagan system of theology, a general name for the infernal deities or gods of hell.—The ancients comprehended under manes not only Pluto, Proserpine, and Minos; but the souls likewise of the deceased were taken into the number, and esteemed gods of hell. It was usual to erect altars and offerings to the manes of deceased friends and relations. One branch of the magic art among the Pagans consisted in consulting the manes of the dead in matters of importance; this was called necromancy. See NECROMANCY.
