to reinvest it with spiritual force; Ugie Erha Oba, which honors the Oba's father and all paternal ancestors; Oduduwa, a masquerade that likewise honors the Oba's paternal ancestors; and Ugie Oro, celebrating Oba Esigie's victory over the Idah Kingdom in the 16th century. Finely carved ivory double gongs are examples of art related to rituals at court. They are called “double” gongs because of second, smaller resonating cups at their front. Typically, the central image is the Oba in coral regalia supported by the high priests Osa and Osuan, officials who tend the altars of the kingdom's two patron gods. These gongs are still carried today by the Oba during Emobo, the last of the empowering rites of the Igue festival. The Oba gently taps the ivory instrument, creating a rhythmic sound to calm and dismiss unruly spirits from the kingdom. Leopard imagery in the arts of Benin The Oba is referred to metaphorically as “the leopard of the house,” and images of the beautiful, cunning, and immensely dangerous cat appear frequently in Benin's royal arts. Before the British invasion in 1897, domesticated leopards were kept in the palace to demonstrate the Oba's mastery over the wilderness.

Coral and red stones such as jasper and agate are also filled with supernatural energy, or ase, as are elephant ivory and brass, two other valuable materials that the Oba has historically controlled. Despite his divine status, the Oba can not rule alone. He must rely on others to fulfill his destiny, a dependence that is physically expressed when he walks or sits with his arms supported at the elbows and wrists by attendants. They help him bear the weight of his regalia, a constant reminder of the burden of kingship. Brass casting Brass casters (igun eronmwon) are the highest-ranking craft guild within the hierarchical structure of the Iwebo society, followed by blacksmiths (igun ematon) and ivory and wood carvers (igbesanwan). The origins of brass casting in Benin are debated. One popular story credits Oba Oguola (enthroned c. 1280) with sending for a master brass caster from Ile Ife, the
