dean_exia said: The unicursal hexagram is indeed by Crowley.
But the eye of Osiris in triangle is pretty dead giveaway that it's related to Masonry.
The OTO (Ordo Templi Orientis) founded by Crowley also uses the eye. In a triangle (piramid) http://upload.wikimedia.org/wikipedia/en/d/d3/OTOlogo.png There’s no single esoteric order who can claim sole ownership to symbols from dead religions. Much less the Masons, who are a lot younger than they try to make themselves look by using said symbols…
