Africa | Belly Mask from the Yoruba people of Benin | ca. 1970s | Among the Yoruba Gelede masquerade is organized every year to celebrate the ‘mothers’ good witches who propitiate and control the power of the ‘bad’ witches who fly at night causing human misfortune, illness, and death. When Gelede appear, they dance in pairs in a tightly structured and complexly choreographed dance accompanied by singing and drumming. Body masks such as this are rare. They appear in exceptional circumstances.
