The Roman Empire
Octavian as Augustus, 27 BC – 14 AD

Octavian received the honourary title of Augustus on 16th January 27. His portrait style as Augustus is a continuation of his ageless portraits used after the battle of Actium, culminating in Augustus' most famous portrait, that of Prima Porta. It was named after a completely preserved statue, now in the Vatican museum, that was found at the site of Livia's villa near Prima Porta outside of Rome. AMP.

Augustus'portraits on sestertii are limited to these Eastern ones and those of Lugdunum, the latter very generic in their stylistical elements. This specimen has a fascinating portrait style. AMP.
