Kumani is the supreme creator and world-founder of the Buduma of the Lake Chad archipelago, the god who set the lake, its islands and its grasses in order and who sends the rains on which the herds and fisheries depend. Beneath a folk-Islamic surface he remains the high god to whom the spirit-appeasing priests ultimately refer, and observers frequently equate him with the God of Islam. Little developed narrative survives: the record preserves his role as maker and provider rather than a cycle of deeds.
