As I talked about in my "African Art in Ritual" discussion, many of the African cultural rituals center around works of art. Masks in particular are popular focus of these rituals. Masks were used as not only a representation of a spirit, but also as a way to channel a spirit. Almost every African culture emphasizes the importance of the spirit world. Spirits were thought to be everywhere and in everything. A spirit could be a deity, an animal, an ancestor and anything in between. Most masks are made primarily out of wood but they are certainly not contained to one medium. Masks can have ceramic, feather, beaded and even human hair components. Masks were used in any type of spiritualistic ritual or performance. The Bwa "Hawk Mask" is a great example of spiritualistic mask. It may have been used in coming of age or seasonal change ceremonies. The Ekoi "crest Helmet" is another great example of a spiritual mask. This mask was probably used in funeral or coming of age ceremonies. I find the curved horns especially striking. Pay close attention to what kind of ceremonies or spirits these masks may represent as they are all unique in their own way.
