The Karikpo Society was charged in the past with insuring agricultural fertility. Karikpo masks typically depict animals such as deer, antelope, goats, and monkeys. The masquerades perform acrobatic feats requiring considerable agility. This is especially true in the case of those wearing horned masks, such s this one, where the masquerader must jump especially high when performing the customary somersaults.
