Oba - King of Benin

Looking at the picture of the Oba of Benin, can you see which is the most important person?
The African artist who made this brass plaque took care to make the man in the middle look bigger than the other people. Why? Because the man with the spiky head dress was an Oba, or king, of Benin in West Africa.
The Oba's attendants hold shields to protect him, and shade him from the hot sun. His royal regalia is made from red coral - a rare imported material.
This piece of art is called a 'Benin bronze', though it's actually made of brass (a mixture or alloy of copper and zinc), not bronze (copper and tin).
