The Primaporta Augustus, in the villa of Augustus' wife Livia, in Rome. It was imitated and copied more than any other statue-type of the emperor in the Empire. Probably a copy of an outsize bronze original made at some date after 20 B.C., it shows Augustus in the favoured attitude of Polyclitus, addressing his troops (adlocutio). His breastplate depicts the return of the Roman standards by the Parthi.
