Geno, also Gueno, is the supreme creator deity of the pastoral Fulɓe of the western Sahel. Tradition-bearers gloss the name from a root meaning 'eternity', presenting him as the eternal and uncreated source of all things. In the celebrated cosmogonic recitation he draws the universe out of an original drop of milk, shaping in succession stone, iron, fire, water and air, and from them the first human being; when death in turn threatens to undo creation, the supreme being descends a third time under the epithet Doondari and overcomes death. Conceived as omnipotent and omnipresent yet remote from daily affairs, Geno does not show himself but works through the primordial serpent Tyanaba. The name survived the conversion of the Fulɓe elite to Islam and is widely used for God in Fulfulde to this day.
