Dogon and Sirius – The Skeptic’s Dictionary – Skepdic.com – Carl Sagan agreed with Temple that the Dogon could not have acquired their knowledge without contact with an advanced technological civilization. Sagan suggests, however, that that civilization was terrestrial rather than extraterrestrial. Perhaps the source was Temple himself and his loose speculations on what he learned from Griaule, who based his account on an interview with one person, Ambara, and an interpreter.
According to Sagan, western Africa has had many visitors from technological societies located on planet earth. The Dogon have a traditional interest in the sky and astronomical phenomena. If a European had visited the Dogon in the 1920’s and 1930’s, conversation would likely have turned to astronomical matters, including Sirius, the brightest star in the sky and the center of Dogon mythology. Furthermore, there had been a good amount of discussion of Sirius in the scientific press in the ’20s so that by the time Griaule arrived, the Dogon may have had a grounding in 20th century technological matters brought to them by visitors from other parts of earth and transmitted in conversation.
Or, Griaule’s account may reflect his own interests more than that of the Dogon. He made no secret of the fact that his intention was to redeem African thought. When Walter van Beek studied the Dogon, he found no evidence they knew Sirius was a double star or that Sirius B is extremely dense and has a fifty-year orbit.
