The emperor is bareheaded, dressed in a tunic and a heavy commander's cloak, called a paludamentum, which is fastened on the right shoulder with a disc pin. On his feet he does not wear patrician shoes, but light military sandals. His right hand is in the gesture of adlocutio, typical of commanders speaking to their soldiers. His left hand, which holds the reins, wears the senator's gold ring, used for sealing.
