Literally, ‘founders’. The divine founding ancestors of Fon clans. When the earth was still sparsely populated the sons of Fa, ‘the word of Mawu-Lisa’, came from the sky to preach ‘the doctrine of destiny, and to foretell that supernatural beings would appear and found family lines’. These tohwiyo started the clans, instituted their laws, and organized their cults. The comparative lateness of this event in Fon mythology is a reflection of the hard struggle this people had to liberate themselves from the Yoruba.
