This particular coin is not visually exceptional since the image of clasped hands recurs on many different coin types. What makes it of interest is the message it carried, and the role this played in Nerva’s attempt to stabilise his position as Domitian’s successor. In order to understand the coin’s significance fully, we must first consider the context in which it was issued.
Nerva became emperor in September of AD 96, the year in which this coin was minted. As such, this would be among the first coins to be issued under his rule. His predecessor, Domitian, had been murdered in the Imperial palace and condemned as a tyrant by the Senate. Looking at the relative stability of Nerva’s rule as emperor, especially when compared to the civil war and instability which followed the death of Nero – the last Emperor to be violently overthrown – it can be easy to forget the dangers that the new Emperor would have faced. The reluctance of the army to shift their loyalties to an unknown Emperor is likely to have been significant in the wake of Domitian’s murder. Domitian had been a generous military leader and his succession by Nerva, who had little experience or prestige in military affairs, risked a crisis like that of the Year of the Four Emperors.
It seems that fortune was in Nerva’s favour, however, as the military situation at that time meant that a military coup was not an option. The all-important Northern armies were engaged in an ongoing war along the frontier; to return to Rome to contest Nerva would mean turning their backs to the enemy and leaving the Empire vulnerable. At the time of his accession Nerva was also already 65 years of age –perhaps they thought he wouldn’t last long enough to be worth overthrowing.
With this in mind, the Concordia Exercituum coin seems perplexing. The legend translates to “Agreement of the armies” referring to unity of armies both with each other – as signified by the military standard, ship’s prow and aquila – and the Emperor. This might seem like a strange choice of message to send at this time to military and non-military inhabitants of the empire. The majority of Romans may have been ignorant of military politics. If this celebration of army unity were aimed at them, wouldn’t it have been like announcing the existence of a previously unknown problem? It would be similar to the captain of a seemingly steady aeroplane announcing ‘There is absolutely no cause for alarm’, a statement that would only invoke suspicion and paranoia. Similarly if the Emperor felt the need to reassure citizens of the army’s loyalty, then that loyalty must be in doubt. As for the military, Nerva was no doubt aware that they would feel anything but unity with a Rome that had murdered their leader and denounced him as a tyrant. To them, receiving such a coin in their salary would surely have been laughable at best, and a grave insult at worse, as Nerva proudly announces that they are loyal to him. As a gold coin, if this type were used in military pay, it would have come into the hands of wealthier officers and individuals.
Considering the events of summer AD 97, it can be argued that Nerva (or his advisors) had taken the wrong strategy with these coins. The Praetorian Prefect, Casperius Aelianus, led the Praetorian Guard to the Imperial Palace to demand the execution of Domitian’s murderers: the freedman Parthenius and Petronius Secundus (Aelianus’ predecessor as Praetorian prefect). Petronius offered his neck to the guards, saying that he would rather die than give into their demands, and was killed immediately. Parthenius was subjected to a much more gruesome fate. He was castrated, likely a deliberate snub to Nerva who had made castration illegal, then strangled to death. The incident deeply embarrassed Nerva, as the military’s disloyalty was demonstrated publicly. It showed his failure to pacify his own army and forced him to name Trajan as his successor. Trajan was a military man, chosen in order to appease the soldiers.
But it is worth considering Nerva’s perspective further before condemning him. He had, after all, already been involved in politics during the civil wars of AD 69, and thus had personal experience in dealing with civil unrest in the aftermath of an emperor’s overthrow. He would have witnessed the events that led to Galba being murdered at the hands of the Praetorian Guard in the centre of the forum. Surely Nerva would have known the care needed to ensure the loyalty of the Roman troops. Nerva appears to have modelled most of his coinage, besides the Concordia Exercituum type, on that of Galba. It makes no sense for him to have designed a new coin, which seemed only to insult the military whose allegiance it was so essential for him to win.
Perhaps we are reading the coin wrong. It has been suggested that one key reason that the troops were hostile to Galba was that he gave no donative to the army. Syme argued that Nerva would remember the danger of forgoing the donative, and would have provided one. If the Concordia Exercituum coin was issued alongside this donative (or formed part of it), then rather than being seen as an arrogant declaration of something that was not true, the type would instead have borne a message of hope: that this gift would inspire concord between Emperor and army. If viewed by someone in Rome, the message may have been read differently. Inhabitants of Rome were surrounded by monuments celebrating Domitian’s military career, and may have viewed Nerva’s proclamation against Domitian’s established military record.
Finally, we should not see the ‘conspiracy’ of Casperius Aelianus as a complete failure on the part of Nerva. The Praetorians under his command only demanded the execution of two men, the murderers of the previous emperor, a demand that Grainger calls ‘surprisingly moderate’. When compared to other successors of overthrown emperors, such as Pertinax and Galba (both of whom were killed by the Praetorian Guard) Aelianus’ conspiracy appears more to be evidence of Nerva’s success, than failure.
This month's coin was chosen and written by Nigel Heathcote. Nigel is a first year MPhil/PhD student in the Department of Classics and Ancient History at Warwick. His PhD is a study of the effects of being condemned as a tyrant upon the ‘physical legacy’ of an emperor in the city of Rome, looking at themes of destruction, appropriation and contrast. His academic interests focus on the propagation of imperial ideas through material culture.
