Royal regalia
One way of distinguishing rank is through ceremonial dress and accessories. The head is often seen as the "seat of the soul" and the noblest part of the body, and elaborate headdresses are almost universally used to indicate high status --- the leader being the "head" of the group. They range from the elaborate feathered headdress of a Native American chief to the richly jeweled crown of a monarch. Many leaders carry a golden globe, or orb (a piece of regalia first used by Roman emperors to show their dominion over the world), and a scepter similar to a staff. In Japan, one of the items of imperial regalia is a bronze mirror, associated with the goddess Amaterasu and passed down to the imperial family, who claim descent from her.
