Our Lady of Endor Coven
Our Lady of Endor Coven, also known as Ophite Cultus Sathanas, was an American Satanic cult founded by Herbert Arthur Sloane (born September 3, 1905, died June 16, 1975) in Cleveland, Ohio, with a claimed origin in 1948 though definitive documentation of the group does not appear until the 1960s. Heavily influenced by Gnosticism, the group equated Sathanas with the Serpent in the Garden of Eden as revealer of true knowledge.
