Dogon Myths of Sirius: Nommos, Po Tolo, and the Contested Claims of Extraterrestrial Knowledge

To the point

Dogon myths from Mali focus on Sirius and its invisible companion Sirius B, with Nommos depicted as amphibious visitors who allegedly shared astronomical knowledge; French researchers Marcel Griaule and Germaine Dieterlen studied these beliefs, while Carl Sagan and others warned that Western contact might have shaped them, and key claims such as Sirius B’s density, orbital details, and a possible third star Emme Ya remain contested.
