It is a mistake to describe a "Nyonyosé tribe" or the "art of the Nyonyosé" because the Nyonyose do not exist outside Mossi society. All Nyonyosé are Mossi. At the same time, it is a mistake to assume that all segments of Mossi society are culturally identical, for the differences between the Nakomsé and the Tengabisi are striking; only the Tengabisi use masks, and only the Nakomsé use figures in the context of political celebrations. The Nakomse are the political class, and the Tengabisi are the spiritual class.
