Ẹrhẹ are round stools with two intertwined serpents as the supporting column. Aside the two serpents, which point in two different directions (up and down), other creatures such as frogs, leopards, roosters and human figures are seen on these stools. The Obah n’uhi pattern of design (which has no beginning or end) is seen at the top of these stools, which shows the supremacy of the Ọba (king/emperor). These are ceremonial stools used by the Benin chiefs when performing rituals in ancestral shrines. According to oral tradition, Ogiso Ẹrhẹ was the first to use a throne.
