Моси
Masks occupy an important position in the religious life of the Nyonyose, the ancient farmers and spiritual segment of society among the Mossi people. The Nakomse (chief class) do not use masks. The use of masks in initiations and funerals is quite typical of all the Voltaic or Gur-speaking peoples, including the Nyonyose, Lela, Winiama, Nouna, Bwaba, and Dogon. Masks appear at burials to observe on behalf of the ancestors that proper burial procedures were carried out. They then appear at several funeral or memorial services held at regular intervals over the years after an elder has died. Masks attend to honor the deceased and to verify that the spirit of the deceased merits admission into the world of ancestors. Without a proper funeral the spirit remains near the home and causes trouble for his/her descendants. Masks are often carved of the wood of "Ceiba pentandra", the faux kapokier. They are carved in three major styles that correspond to the styles of the ancient people who were conquered in 1500 by the invading Nakomse and integrated into a new Mossi society: In the north masks are vertical planks with a round concave or convex face. In the southwest masks represent animals such as antelope, bush buffalo, and various strange creatures, are painted red, white and black. In the east, around Boulsa [3], masks have tall posts above the face to which fiber is attached, . Female masks have two pairs of round mirrors for eyes, and small masks, representing Yali, "the child" have two vertical horns. All Nyonyose masks are worn with thick costumes made of the fiber of the wild hemp, "Hibiscus cannabinus", In the old days only the northern Nyonyose in Yatenga and Kaya, and the eastern people around Boulsa allowed their masks to be photographed. The people in the southwest forbade photography because it did not conform to the "yaaba soore", the path of the ancestors. Mask characters include Balinga, the Fulani woman, katre, the hyena, nyaka, the small antelope, Wan pelega, the large antelope, and many others. Now, however, masks from all three areas appear at annual public festivals such festivals as SIAO (Fr. Salon international de l’Artisanat de Ouagadougou), Week of the Culture, and the Atypical Nights of Koudougou (Les Nuits Atypiques de Koudougou). Each Nyonyose family has its own mask, and they are charged with protecting the masks to this day. Masks are very sacred, and are a link to the spirits of ancestors and of nature.
