The marble statue was made shortly after Augustus’ death. Some believe it may have been a copy of a bronze statue that celebrated his victory over the Parthians in 20 BC. My erstwhile teacher of Mediterranean archaeology disagreed with that assertion, since Augustus had been very careful not to have himself depicted as a military leader – at least not in public. There were a number of reasons for that.
First of all, Augustus carefully presented an image of himself as restraint and sober, as well as pious. Indeed, his name – Augustus – has a distinctly religious ring to it, and many portraits intended for public consumption tended to present him as a civilian or dressed like a priest (since he also officiated). Secondly, Augustus had “saved” the Republic from decades of internal strife and had ushered in a new era of peace, the Pax Romana, and it’s likely that he would not have wished to emphasize his military achievements.
There is also another reason: Augustus was a shrewd politican, but a poor general. Fortunately, he could rely on men who were better warriors than he was. As a result, it would not have made a lot of sense to depict himself as a conquering general, since that would undercut his military allies, on whose loyalty he depended to secure his rule.
And speaking about military accomplishments, the scene on the cuirass deserves to be examined in closer detail. In the centre, a figure in baggy trousers is giving a standard to a Roman soldier. Individuals in trousers are invariably barbarians (i.e. non-Greek and non-Roman):
The trousered individual is meant to be a Parthian. The scene commemorates a moment that had been a great political win for Augustus: the return of the Roman standards that the Parthians had taken after their defeat of Crassus at the Battle of Carrhae in 53 BC. To be sure, this was a political win, not a militarily one, since the return of the standards had been brokered along diplomatic channels.
The Roman soldier has been interpreted as representing Tiberius, who was present when the Parthians returned the standards. Tiberius was a son of Livia’s from an earlier marriage. Augustus had no living heirs of his own and had, at long last, grudgingly accepted Tiberius as his son and successor. If this interpretation is correct, it would further argue in favour of the statue being made after Augustus’ death, and displayed at Livia’s villa.
Finally, the figures that frame this scene are all divinities: we see e.g. the sky god at the top and Mother Earth near the bottom. Symbolically, the gods represent divine sanction of Augustus’ peace. Furthermore, the horn of plenty, held in Mother Earth’s hands, symbolizes the wealth that Augustus’ peace has brought to the Roman Empire.
On Twitter, user @e-pe-me-ri pointed out this article that suggests the soldier represents Roma, the personification of the city of Rome. The soldier does appear to have feminine features, and the type of helmet is often associated with Roma. There are also doubts about whether or not the trousered figure is really a Parthian. Nevertheless, the main message of the cuirass (victory, prosperity, divine sanction) remains intact.
One of the key things that Augustus did to ensure his reign would be successful was to use art and architecture as propaganda. To celebrate his defeat of Caesar’s assassins, he contructed a temple to Mars Ultor (i.e. “Mars the Avenger”), which featured statues of Mars (the god of war), his paramour Venus (goddess of love), as well as a statue of the recently deified Julius Caesar himself.
The reason for this was obvious to any Roman: the clan of the Julii traced back their ancestry to Ascanius, the son of Aeneas, the Trojan who had fled Troy after it had been destroyed by the Greeks and who eventually settled his people in Latium, where ultimately the city of Rome would be founded. Ascanius was given a second name, Julus, from which the clan derived its name. Since Aeneas himself had been the son of Venus, this meant that the Julii themselves could claim divine descent from that goddess.
In Roman times, an adopted child had the exact same rights and status as biological offspring. Augustus could thus lay claim to the same divine ancestry as Julius Caesar himself. Venus was associated with dolphins (once myth after all suggests she was born in the
