Ilo, son of Yaladi, is the primordial first herdsman of Fulani cosmology, paired in tradition with the serpent Tyanaba as his brother. When the cattle followed Tyanaba into the depths of Lake Debo, Ilo tapped and drove them out in the darkness, founding the pastoral vocation of the Fulani. He stands at the head of the line of herders whose sacred knowledge the initiatory tradition transmits.
