The rude Californian rite which we have just considered has a close parallel in the religion of ancient Egypt. The Thebans and all other Egyptians who worshipped the Theban god Ammon held rams to be sacred and would not sacrifice them. But once a year at the festival of Ammon they killed a ram, skinned it, and clothed the image of the god in the skin. Then they mourned over the ram and buried it in a sacred tomb. The custom was explained by a story that Zeus had once exhibited himself to Hercules clad in the fleece and wearing the head of a ram.(304) Of course the ram in this case was simply the beast-god of Thebes, as the wolf was the beast-god of Lycopolis, and the goat was the beast-god of Mendes. In other words, the ram was Ammon himself. On the monuments, it is true, Ammon appears in semi-human form with the body of a man and the head of a ram.(305) But this only shows that he was in the usual chrysalis state through which beast-gods regularly pass before they emerge as full-fledged anthropomorphic gods. The ram, therefore, was killed, not as a sacrifice to Ammon, but as the god himself, whose identity with the beast is plainly shown by the custom of clothing his image in the skin of the slain ram. The reason for thus killing the ram-god annually may have been that which I have assigned for the general custom of killing the god and for the special Californian custom of killing the divine buzzard. As applied to Egypt, this explanation is supported by the analogy of the bull-god Apis, who was not suffered to outlive a certain term of years.(306) The intention of thus putting a limit to the life of the god was, as I have argued, to secure him from the weakness and frailty of age. The same reasoning would explain the custom—probably an older one—of putting the beast-god to death annually, as was done with the ram of Thebes.
