(M63) It is said that at the festival of the Wolf-god Zeus, held every nine years on the Wolf-mountain in Arcadia, a man tasted of the bowel of a human victim mixed with the bowels of animals, and having tasted it he was turned into a wolf, and remained a wolf for nine years, when he changed back again into a man if in the interval he had abstained from eating human flesh.(224) The tradition points to the existence of a society of cannibal wolf-worshippers, one or more of whom personated, and were supposed to embody, the sacred animal for periods of nine years together. Their theory and practice would seem to have agreed with those of the Human Leopard Societies of western Africa, whose members disguise themselves in the skins of leopards with sharp claws of steel. In that guise they attack and kill men in order to eat their flesh or to extract powerful charms from their bodies.(225) Their mode of gaining recruits is like that of the Greek Wolf Society. When a visitor came to a village inhabited by a Leopard Society, “he was invited to partake of food, in which was mixed a small quantity of human flesh. The guest all unsuspectingly partook of the repast, and was afterwards told that human flesh formed one of the ingredients of the meal, and that it was then necessary that he should join the society, which was invariably done.”(226) As the ancient Greeks thought that a man might be turned into a wolf, so these negroes believe that he can be changed into a leopard; and, like the Greeks, some of them fancy that if the transformed man abstains during his transformation from preying on his fellows he can regain his human shape, but that if he once laps human blood he must remain a leopard for ever.(227)
