The Sirius Mystery is a book by Robert K. G. Temple (1976) in which he describes the extraordinary of the primitive African Dogon tribe of Mali in former Sudan. The tribe was apparently aware for centuries that the Dog Star Sirius was orbited by a white dwarf neighbor that is invisible to the naked eye, but was recently discovered.
Temple contends that this knowledge of the Dogon tribe was five thousand years old, and also was known by the ancient Egyptians in the pre-dynastic times prior to 3200 BC, and the Dogon people could be partially descent from them. A.G.H.
