Dogon people live in an area of Mali, West Africa and are known for their artwork, ceremonial masks, and the belief in an amphibious deity called Nommos.Given their remote location, it is difficult to imagine Dogon spiritual beliefs were influenced by field researchers prior to the 1930s.

Marcel Griaule, a French anthropologist spent several years talking and recording dialogue with a Dogon wiseman named Ogotemmeli, from which he developed the main body of his research. The tribe told Griaule about Sirius and its two companion stars, an extraordinary claim by a remote tribe believed to be living in near isolation prior to the anthropologist's first visit.

Western astronomers believed at least one companion star existed at the time confirmed by Friedrich Bessel's studies, and by telescope observations performed by Alvan Graham Clark and Walter Sydney Adams. A small star also observed during a short period between 1920 and 1930 suggested the possibility of a third star existing in the Sirius system. This third star, Sirius C, is theorized to exist based on model data from the NASA Astrophysics European Southern Observatory based on a six year perturbation period between Sirius A and B, is due to a very faint third body in the system at a maximum 15-20 absolute magnitude.
