I have finally read 'The Sirius Mystery' after many years of reading about it secondhand. It appears most authors either love or loathe Robert Temple's theory. Although like the majority of readers, I will take a lot of convincing about alien contact, the effort of the author in trying to make sense of the beliefs of the Dogon in the light of better known Egyptian, Sumerian and Greek myth is impressive to say the least. I found myself checking sources and alternative explanations, reaching the conclusion that Robert Temple is a careful and honest scholar. Read the book and see for yourself!
PS..A comment passed on by Michael Palin was good: "How many people are there in an average Dogon Family? Five: Two adults, two children and a French Anthropologist!"
