Stone Sigil

The prolific Copper Centipede returns with this occult sigil carved from stone. 

The sigil consists of what appears to be a 5-armed, 3 eyed starfish-like creature (or creature's head...?) passing through a thick circular boundary, forming an inverted pentacle. The figure transcending the bounds of the circle may be interpreted as a depiction of the entity phasing from one realm into another. This implies it may have been used as part of a most sinister summoning ritual.

The imagery shares features associated with the Elder Sign (an upright pentagram-like symbol of protection from the Old Ones) and descriptions of the Black Goat of the Woods (also affiliated with/known as Shub-Niggurath). It also bears resemblance to the Sigil of Baphomet suggesting it may be of more modern origin, likely from an underground new age cult of amalgamated ideology centered around the worship of an entity sharing attributes of the more traditional Satan and the unwholesome and perverse Black Goat. One shudders to think where this may be going on...
