This Kuba wood divination animal, itoombwa, is of attenuated form, with carved designs and pigment. Made of wood, this "rubbing oracle" was used as a divination tool. The diviner rubbed the wooden attachment over the back of the animal figure. If it stuck, the person was guilty. "A crocodile never lies" was a local saying. This piece appears to be a crocodile, simplified and abstracted, with notched teeth and a long tail. Representative Kuba diamond designs are carved on the side, legs, and tail. Evidence of red pigment, possibly tukula powder, is visible in the recessed areas.
