The Bobo of Burkina Faso believe that the earth was created by the supreme being Wuro. During the creation of man, Wuro also produced masks to act as physical representations of his son Duwo through which man could communicate with Wuro.
Viewed as one of the most sacred of all Bobo masks (second only to the molo mask), nwenka (pl. nwenke) is used exclusively by Bobo blacksmiths in cults centred around Dwo's spirit (the kwele dwo, dwosa, and sibe dwos cults). Nwenke masks are used during male cult initiation ceremonies, during annual harvest festivals, as points of sacrifice and prayer to Wulo and also during funerals of cult members.
