Note the feathered headdress of the Priest on the Throne. Those are feathers on the sides of the crown of the figure on the throne in the Hieroglyph. In Egyptian each person's life (heart) is measured against the weight of the feather of justice. Maybe that is why the American Indian brave wears a single feather, to signal he is just, whereas the chief wears a many feathered headdress to signal he is the judge."
