Julian stood transfixed at this view of perhaps the largest crowd he had seen in his life. His reverie was broken by the booming voice of the Emperor, who stood beside him. Even with Constantius' powerful vocal range, however, and the excellence of the plaza's acoustics, the size of the crowd required that heralds be posted along the edges to pick up the gist of the Emperor's words and relay them in their own bellowing shouts to the crowds in the back of the space and beyond to the nearby streets of the city, where the multitudes were continuing to arrive to witness the extraordinary event.
'Soldiers and citizens!' the Emperor shouted. 'I come before you to plead your impartial judgment for the step I am about to take.' The crowd fell silent as his words echoed along the sides of the stone buildings ringing the plaza, and were taken up and reechoed by the relays of heralds.
'As you are aware, the barbarians, as if to appease their unhallowed gods with an offering of Roman blood, have disturbed the peace of our western frontier, and are raging through Gaul. In so doing, they are relying on the fact that harsh necessity requires that my attention be devoted to events at the other end of the Empire. If this mischief is countered while there is still time, by measures that have your united support, the criminal insolence of these animals will subside, and the Empire's frontiers will remain sacrosanct. It is for you to strengthen my hope for the future, and to approve my decision.'
He paused a moment to allow the heralds time to relay his words. The soldiers in the front ranks stared up with wide eyes beneath their bronze visors, at the Emperor and his young cousin, who slouched beside him.
'You see before you: our Julian!' he resumed with a bellow. 'My cousin! As dear to me for his personal qualities as for his kinship, a man of exceeding intelligence! It is Julian whom I propose to elevate to the rank of Caesar, to serve directly under me in my capacity as Augustus, a proposal which must be ratified by you, should you deign to grant your approval.'
Constantius again paused for a moment, to allow the expected applause and shouts of acclamation to rise from the crowd. What we heard instead was puzzled muttering among the troops, broken only by the receding calls of the heralds in the distance. Julian seemed to shrink even further into himself with embarrassment. Constantius, determined to wring an acclamation out of the crowd if he had to stand there all night, had just taken a breath to begin his harangue again, when a single centurion rose and shouted enthusiastically that it was the will of God. 'Ave, Julianus Caesar!' he cried. The man had obviously been planted in advance.
Nevertheless, the men in that centurion's company joined in their leader's example. 'Ave, Julianus Caesar!' cried sixty or seventy other desultory voices, a shout that was immediately taken up by several other companies scattered around the plaza and by the heralds on the perimeter, themselves doing their level best to stir the crowd's excitement. Slowly, almost reluctantly the volume of cheers mounted, filling the plaza and spreading to the mob thronging the streets beyond.
Constantius' round, sweating face broke into a broad smile. As he turned to Julian, his mouth remained fixed in its grin, though his eyes narrowed. Glancing briefly to a point behind his cousin, he gave a slight nod. Immediately an enormous eunuch, a Sicilian giant who normally performed menial tasks around the palace, stepped forward, dressed in the elaborate furs and plaid cloth breaches of a Gallic chieftain, his face painted with horrifying blue stripes, a gaudy hairpiece with long russet braids draping down his back, silver serpent-shaped bangles clamped around his massive biceps. The crowd fell into awestruck silence as the man walked ponderously to Julian's side, carrying a large bundle, which he shook out with a deliberate, dramatic flourish. He draped the heavy purple embroidered cloak over the new Caesar's shoulders and fell prostrate at the young man's feet in a position of abject fear.
As Julian stood staring in a combination of wonder and mortification at the huge trembling man, another roar went up from the crowd, this time accompanied by the deafening rattle of shields as the troops clashed them against their knees with a fearsome din. It was only later, after my careful explanation to him, that he understood that this was an indication of the troops' complete approval, and was, in fact, much to be preferred to their striking their shields with their spears, a sign of rage and grief.
'Beloved cousin!' Constantius shouted above the roar. 'You have thus attained, while still young, the distinction for which you were destined by your ancestry. Be therefore my partner in toil, my colleague in danger! Assume for yourself the government of Gaul! Relieve its suffering people by generous treatment! Meet the enemy in battle, and raise high the standards of your legions! Command these men, whose valor matches your own! We will wage war simultaneously; we will aid one another with constant and mutual affection; and God willing, we will govern together, collaborators in righteousness and humility, over a world finally at peace.'
The men cheered wildly, and the Emperor raised Julian's hand in his own, high over their heads, acknowledging the vast and rather incompetently choreographed demonstration of approval. When the applause continued even after many moments, Constantius led him to a sedan chair that had been positioned at the side of the platform, and which was borne by eight slaves, all of them costumed identically as fierce Gallic warriors. After the Emperor and his new Caesar had clambered onto the broad, carved, and curtained bench, the slaves carefully lifted their poles and lumbered, rocking, around the circuit of the massive plaza to the general acclaim of the thronging crowd. They were led by a squad of fifty hard-muscled Praetorians who cleared a path through the mob, sometimes with the flats of their swords. Julian stared out into the middle distance, his expression impossible to read. The slaves finally conveyed the two men back to the foot of the platform, where they stepped out and with a concluding wave, walked arm in arm back through the double doors into the reception hall.
Once inside, Julian threw off the stifling purple cloak and stuffed it into the arms of the nearest slave, as Constantius watched coldly, though with an amused gleam in his eye.
'You might have warned me,' Julian muttered accusingly, certain now of his physical safety for at least the time being, and unconcerned with any offense he might give to the Emperor. 'I have been weeks in Milan, begging you for an answer, any answer, as to why you might have brought me here. And this is how you tell me?'
Constantius snorted. 'A life of command is full of surprises, young Julian. To this you must become accustomed.' He paused, and then glanced at his young cousin with a wry smile. 'Actually, I confess I may be as astonished as you. As late as yesterday, I was still undecided as to whether to erect a gallows or an investiture platform. You should be down on your knees thanking God. You have a very persuasive patroness in the palace.'
Julian stared, bewildered. 'Persuasive?' he said. 'This is a reward? You pluck a poor student from his studies, make him commander of six legions, and order him to defend Gaul? This is merely a slower form of execution than the one you had planned! "Shrouded in death's dark purple by almighty fate…"'
Constantius chuckled. 'Very perceptive of you — and clever use of Homer, though somewhat melodramatic, I would say. But please — don't flatter yourself that you will actually have any role in commanding these men. You would merely be in the way. The western legions will remain under the control of Ursicinus and Marcellus. Barbatio will assist in several capacities, as he has in the past. With you as Caesar, the Empress Eusebia is content, though only God knows why. With Marcellus in command, my generals are content. And you, my boy, will enjoy the ride and keep your nose out of the way.'
