“The Kwele tribe live on the northern frontier of the Republic of Congo, and have produced a famous type of mask called Ekuk. It displays a flat surface and often has a whitened heart-shaped face, a triangular nose and coffee bean eyes. These masks were hung in their houses and rarely worn during dances related to the initiation ceremonies of the Bwete cult. Their function was to ‘warm up’ the village atmosphere in order to activate the beneficial forces resident in the Bwete box.”
