Luba art relates most commonly to the Kings and Chiefs of the Congolese Luba tribe, who would assert their power by display of ceremonial objects during ceremonies. Stools were considered to be the most important of these objects as they would serve not only as a seat but as a receptacle for the Chief’s spirit. The ruler is thus figuratively and literally supported by a caryatid figure - in this case both male and female standing figures. The male is seen with inset cowrie shell eyes, believed by many African tribes to contain divine powers.
