Summanus

Summanus is a being created by British author Brian Lumley for his short story "What Dark God?" (, 1975). 
==Description==
Appearing as a grotesque, mouthless humanoid with pale tentacles sticking out from under his robes, Summanus can use these appendages to siphon blood from his victims.
Summanus had a following in Roman times, but if he is worshipped today, his cult is even more secretive. The rites needed for the proper worship of Summanus are found in the Tuscan Rituals.
==Behind the Mythos==
Brian Lumley based this Great Old One on the Roman deity of the same name mentioned in the poet Ovid's Fasti. It first appeared in the short story "What Dark God?" (1975), and was later incorporated into the greater Cthulhu Mythos by Chaosium when they included it in the Malleus Monstrorum sourcebook for their Call of Cthulhu () roleplaying game.
