The Dogon tell the legend of the Nommos, awful-looking beings who arrived in a vessel along with fire and thunder. The Nommos, who could live on land but dwelled mostly in the sea, were part fish, like merfolk (mermaids and mermen). Similar creatures have been noted in other ancient civilizations -- Babylonia’s Oannes, Acadia’s Ea, Sumer’s Enki, and Egypt’s goddess Isis. It was from the Nommos that the Dogon claimed their knowledge of the heavens.
