Augustus, their new master had called himself, ‘The Divinely Favoured One’. The great-nephew of Julius Caesar, he had waded through blood to secure the command of Rome and her empire – and then, his rivals once dispatched, had coolly posed as a prince of peace. As cunning as he was ruthless, as patient as he was decisive, Augustus had managed to maintain his supremacy for decades, and then to die in his bed. Key to this achievement had been his ability to rule with rather than against the grain of Roman tradition: for by pretending that he was not an autocrat, he had licensed his fellow citizens to pretend that they were still free. A veil of shimmering and seductive subtlety had been draped over the brute contours of his dominance. Time, though, had seen this veil become increasingly threadbare. On Augustus’s death in AD 14, the powers that he had accumulated over the course of his long and mendacious career stood revealed, not as temporary expediencies, but rather as a package to be handed down to an heir. His choice of successor had been a man raised since childhood in his own household, an aristocrat by the name of Tiberius. The many qualities of the new Caesar, which ranged from exemplary aristocratic pedigree to a track record as Rome’s finest general, had counted for less than his status as Augustus’s adopted son – and everyone had known it.
Tiberius, a man who all his life had been wedded to the virtues of the vanished Republic, had made an unhappy monarch; but Caligula, who had succeeded him in turn after a reign of twenty-three years, was unembarrassed. That he ruled the Roman world by virtue neither of age nor of experience, but as the great-grandson of Augustus, bothered him not the slightest. ‘Nature produced him, in my opinion, to demonstrate just how far unlimited vice can go when combined with unlimited power.’4 Such was the obituary delivered on him by Seneca, a philosopher who had known him well. The judgement, though, was not just on Caligula, but on Seneca’s own peers, who had cringed and grovelled before the Emperor while he was still alive, and on the Roman people as a whole. The age was a rotten one: diseased, debased, degraded.
Or so many believed. Not everyone agreed. The regime established by Augustus would never have endured had it failed to offer what the Roman people had come so desperately to crave after decades of civil war: peace and order. The vast agglomeration of provinces ruled from Rome, which stretched from the North Sea to the Sahara, and from the Atlantic to the Fertile Crescent, reaped the benefits as well. Three centuries on, when the nativity of the most celebrated man to have been born in Augustus’s reign stood in infinitely clearer focus than it had done at the time, a bishop named Eusebius could see in the Emperor’s achievements the very guiding hand of God. ‘It was not just as a consequence of human action,’ he declared, ‘that the greater part of the world should have come under Roman rule at the precise moment Jesus was born. The coincidence that saw our Saviour begin his mission against such a backdrop was undeniably arranged by divine agency. After all – had the world still been at war, and not united under a single form of government, then how much more difficult would it have been for the disciples to undertake their travels.’5
Eusebius could see, with the perspective provided by distance, just how startling was the feat of globalisation brought to fulfilment under Augustus and his successors. Brutal though the methods deployed to uphold it were, the sheer immensity of the regions pacified by Roman arms was unprecedented. ‘To accept a gift,’ went an ancient saying, ‘is to sell your liberty.’ Rome held her conquests in fee; but the peace that she bestowed upon them in exchange was not necessarily to be sniffed at. Whether in the suburbs of the capital itself, booming under the Caesars to become the largest city the world had ever seen, or across the span of the Mediterranean, united now for the first time under a single power, or in the furthermost corners of an empire whose global reach was without precedent, the pax Romana brought benefits to millions. Provincials might well be grateful. ‘He cleared the sea of pirates, and filled it with merchant shipping.’ So a Jew from the great Egyptian metropolis of Alexandria, writing in praise of Augustus, enthused. ‘He gave freedom to every city, brought order where there had been chaos, and civilised savage peoples.’6 Similar hymns of praise could be – and were – addressed to Tiberius and Caligula. The depravities for which both men would end up notorious rarely had much impact on the world at large. It mattered little in the provinces who ruled as emperor – just so long as the centre held.
Nevertheless, even in the furthest reaches of the Empire, Caesar was a constant presence. How could he not be? ‘In the whole wide world, there is not a single thing that escapes him.’7 An exaggeration, of course – and yet due reflection of the mingled fear and awe that an emperor could hardly help but inspire in his subjects. He alone had command of Rome’s monopoly of violence: the legions and the whole menacing apparatus of provincial government, which existed to ensure that taxes were paid, rebels slaughtered, and malefactors thrown to beasts or nailed up on crosses. There was no need for an emperor constantly to be showing his hand for dread of his arbitrary power to be universal across the world. Small wonder, then, that the face of Caesar should have become, for millions of his subjects, the face of Rome. Rare was the town that did not boast some image of him: a statue, a portrait bust, a frieze. Even in the most provincial backwater, to handle money was to be familiar with Caesar’s profile. Within Augustus’s own lifetime, no living citizen had ever appeared on a Roman coin; but no sooner had he seized control of the world than his face was being minted everywhere, stamped on gold, and silver, and bronze.*1 ‘Whose likeness and inscription is this?’ Even an itinerant street-preacher in the wilds of Galilee, holding up a coin and demanding to know whose face it portrayed, could be confident of the answer: ‘Caesar’s.’8
No surprise, then, that the character of an emperor, his achievements, his relationships and his foibles, should have been topics of obsessive fascination to his subjects. ‘Your destiny it is to live as in a theatre where your audience is the entire world.’9 Such was the warning attributed by one Roman historian to Maecenas, a particularly trusted confidant of Augustus’s. Whether he really said it or not, the sentiment was true to the sheer theatricality of his master’s performance. Augustus himself, lying on his deathbed, was reported by Suetonius to have asked his friends whether he had played his part well in the comedy of life; and then, on being assured that he had, to have demanded their applause as he headed for the exit. A good emperor had no choice but to be a good actor – as too did everyone else in the drama’s cast. Caesar, after all, was never alone on the stage. His potential successors were public figures simply by virtue of their relationship to him. Even the wife, the niece or the granddaughter of an emperor might have her role to play. Get it wrong, and she was liable to pay a terrible price; but get it right, and her face might end up appearing on coins alongside Caesar’s own. No household in history had ever before been so squarely in the public eye as that of Augustus. The fashions and hairstyles of its most prominent members, reproduced in exquisite detail by sculptors across the Empire, set trends from Syria to Spain. Their achievements were celebrated with spectacularly showy monuments, their scandals repeated with relish from seaport to seaport. Propaganda and gossip, each feeding off the other, gave to the dynasty of Augustus a celebrity that ranked, for the first time, as continent-spanning.
