" The myths of the Dogon tribesmen of mall, west Africa, contain astronomial knowledge which the native people could have neither learned by themselves nor guessed. Obviously, the researchers say, some more advanced civilization told them. These fascinating Dogon legends speak of jupiter's four moons and saturn's rings, which were not seen by human beings until the invention of the telescope. They speak of the star sirius and of a pair invisible companions. One of them circles sirius every fifty years, the legends declare, and is made of metal that is the heaviest thing in the universe. Astronomers have discovered that such an object (called "Sirius-B) does exist but only the most sophisticated and sensitive instruments... Unavailable, of course, to the Dogon- - can detect it."
