Kuosi (Grassfields regulatory society)
Bamileke regulatory society restricted to titled men and royalty; its signature is the elephant mask worn at palace festivals and royal funerals as an insignia of rank, not a religious cult object.
Kuosi is a regulatory society of the Bamileke fondoms of the western Cameroon Grassfields whose membership is restricted to titled men, royalty and senior warriors. Its public face is the elephant-mask costume — a cloth-and-bead helmet with splayed lateral trunk and ear panels, indigo cloth body, and bell-anklets — worn at major palace festivals and at the funerals of fons (chiefs). The elephant is the royal animal of Grassfields cosmology, associating its wearer with sovereign authority; the mask is an insignia of titled rank rather than a religious cult object. Kuosi is sometimes described in older literature as a 'secret society', a label that obscures its function as a political and judicial body whose members performed witchcraft detection, internal arbitration and palace ceremonial duties.
Per Tamara Northern (The Art of Cameroon, 1984) and Pierre Harter (Arts anciens du Cameroun, 1986), Kuosi masks are diagnostic of Bamileke production and should not be confused with Bamum court helmets, whose construction and ceremonial function differ.
