Among the Lega, masks of different materials, sizes, and shapes were used in initiations of the Bwami association. Bwami was responsible for instructing its members in a shared moral philosophy. The teachings were conveyed through proverbs, with both handmade and natural objects serving as memory aids. Instead of being worn in front of the face, masks were held in the hands, hung on fences, or even pulled over the ground with their long raffia beards.
