Aro Ododua are ritual masks that have two forms: male – Uwen – and female – Ọra. According to oral tradition, when Ọranmiyan left Uhe, he brought two totems, Uwen and Ọra. The male is identified by the four suborbital marks that identify a Benin man. Uwen guarantees that the Ọba survives at war, no matter how terrible the war is. Ọra guarantees the productivity of the Ọba, as he must always have children. They are also known as the two royal deities – Ẹbọ n’ẹdo. They can only be produced by guilds when commissioned by the Ọba.
