This helmet mask was made by an unknown Yoruba artist from Nigeria. The mask is worn in an Egungun ceremony where ancestors come out to be honored by the community, and is a time for the community to come together and honor a shared past. They are still performed today and can be draws for tourists from around Nigeria. Masks are often personal to the masquerader, so many of the meanings of this specific mask are unknown without details from the artist. This particular one does have the familiar symbol of the ouroboros, with the snake eating the animal which is eating the snake, representing infinity or a never-ending cycle.
