Totem is the representation of a symbol by an animal, and totemism is the system or science of such symbolism. Thus, in Egyptian mythology, what is represented as a pig or hippopotamus by one tribe, is (for some totemic reason) represented as a crocodile by another.
The apparent wealth of [Egyptian] mythology depends on the totemism of the inhabitants of the Nile Valley . Each district had its own special animal as the emblem of the tribe dwelling in that locality.Lockyer: Nineteenth Century, July 1892, p. 51.
