"There is no doubt", he said of Egyptian religions in "Osiris and the Egyptian Resurrection" (1911), "that the beliefs examined herein are of indigenous origin, Nilotic or Sûdânî in the broadest signification of the word, and I have endeavoured to explain those which cannot be elucidated in any other way, by the evidence which is afforded by the Religions of the modern peoples who live on the great rivers of East, West, and Central Africa . . . Now, if we examine the Religions of modern African peoples, we find that the beliefs underlying them are almost identical with those Ancient Egyptian ones described above. As they are not derived from the Egyptians, it follows that they are the natural product of the religious mind of the natives of certain parts of Africa, which is the same in all periods."
