==== The Four Priests (1946-1950) ====
Between 1946 and 1950, four Dogon head priests revealed the specific details of the Sirius system to Griaule and Dieterlen: the orbital period, density, and properties of Po Tolo. These four informants are the direct source of the most astronomically precise material in the record. Their status as high-ranking initiates is cited by defenders of the tradition's authenticity; their very small number and specific connection to Griaule is cited by skeptics.
