One element of the Griaule material became famous far beyond anthropology: the report, published by Griaule and Dieterlen in 1950, that the Dogon possessed traditional knowledge of Sirius B, the faint white-dwarf companion of Sirius that is invisible to the naked eye, its existence, its density, and its roughly fifty-year orbit. Robert Temple's popular book The Sirius Mystery (1976) built on this to suggest ancient contact, whether with distant travellers or with extraterrestrials. The claim does not withstand examination and should not be presented as fact.
Van Beek's later fieldwork did not find the Sirius doctrine among the Dogon at all; critics note that European visitors, missionaries and popular astronomy had reached the region well before 1950, that Sirius B had been known to Western science since the 1860s, and that the "knowledge" may have entered through contact and then been read back as ancient. The episode is best understood as a case study in how a contested ethnographic report can harden, in popular retelling, into a myth of its own, and the living Dogon veneration of Amma as creator stands quite apart from it.
