Featuring a male figure on horseback, presumably a chief, flanked by four attendents, two women in front followed by two men in the back, the McCormick Ajere Ifa is a sculptural tour-de-force work by an unknown Yoruba artist from the Ketu region who was active in the middle of the 19th century. Two other works by the same hand are known, both in the collection of the Art Institute of Chicago: a stool for a Shango altar (inv. no. "2002.276") and an Eshu scepter (inv. no. "1991.396"). Elaborately carved bowls such as the McCormick Ajere Ifa were receptacles for the sixteen palm nuts and other equipment used during the ifa divination oracle. Its complex iconography, splendid quality and sheer size attest to its ritual importance and suggest that it was commissioned by a diviner of high status.
