This belief is known as totemism, and its adoption was the means of laying the foundation of a widespread system of tribal rule and custom, by which marriage and many of the affairs of life were and are wholly governed. Probably all European and Asiatic peoples have passed through this stage, and its remains are to be found deeply embedded in our present social system. {82} Totemic Law and Custom Few generations would elapse before the sense of ancestral devotion to the totem or eponymous forefather of the tribe would become so strong as to be exalted into a fully developed system of worship of him as a deity. That the totem develops into the god is proved by the animal likeness and attributes of many deities in lands widely separate. It accounts for the jackal- and ibis-headed gods of Egypt, the bull-like deities of Assyria, the bestial gods of Hindustan--possibly even for the owl which accompanied the Grecian Pallas, for does not Homer speak of her as 'owl-eyed'? May not this goddess have developed from an owl totem, and may not the attendant bird of night which perches on her shoulder have been permitted to remain as a sop to her devotees in her more ancient form, who objected to her portrayal as a human being, and desired that some reminder of her former shape might be preserved? That our British ancestors possessed a totemic system is undoubted. Were not the clan Chattan of the Scottish Highlands the "sons of the cat"? In the _Dean of Lismores Book_ we read of a tribe included under the "sons to the king of Rualay" one battalion of whom was 'cat-headed,' or wore the totem crest of the cat. The swine-gods and other animal deities possessed by the British Celts assist this theory, as do the remains of many folk-customs in England and Scotland. Our crests are but so many family symbols which have come down to us from the distant days when our forefathers painted them upon their shields or wore them upon their helmets as the badge of their tribe, and thus of its supposed beast-progenitor or protector.
