“Fang tribespeople migrated from the north-west during the 18th and 19th centuries and are today scattered across southern Cameroon, Equatorial Guinea and Gabon. They are principally hunters, but also farm. Fang social structure is based on the clan, a group of individuals with a common ancestor, and on the family. They also maintain tribal cohesion through the So and Gil societies. Each family possessed a Byeri, or reliquary box, in which the bones of famous ancestors were kept. The box was kept by the Esa, the eldest man in the family. “
