This article is written on a topic within the Greater Cthulhu Mythos based on information from works in the Mythos. By default, all information is to be assumed to derive from the Lovecraft Myth Cycle unless otherwise marked.

Extended universe sigil

Summanus appears as a grotesque, mouthless humanoid with pale tentacles sticking out from under his robes. He can use these tentacles 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 MythosEdit

Summanus is the creation of Brian Lumley — who based the Great Old One on the Roman deity of the same name — and first appeared in Lumley's short story "What Dark God?" (1975).
