8. Then he assailed the memory of Constantine also as an innovator and a disturber of established laws and of customs received from ancient times, accusing him of having been the first to promote barbarians to the fasces and robe of the consul. But in this respect he spoke with folly and levity, since, in the face of what he so bitterly reproved, he a very short time afterwards added to Mamertinus, as his colleague in the consulship, Nevitta, a man neither in rank, experience, or reputation at all equal to those on whom Constantine had conferred that illustrious magistracy, but who, on the contrary, was destitute of accomplishments and somewhat rude; and what was less easy to be endured, made a cruel use of his high power. XI. § 1. While Julian was occupied with these and similar thoughts, and was anxious about great and important affairs, a messenger came with terrible and unexpected news of the monstrous attempts of some persons which were likely to hinder his fiery progress, unless by prompt vigilance he could crush them, before they came to a head. I will briefly relate what they were. 2. Under pretence of urgent necessity, but in reality because he still suspected their fidelity to him, he had sent into Gaul two legions belonging to the army of Constantius, with a troop of archers which he had found at Sirmium. They, moving slowly, and dreading the length of the journey and the fierce and continual attacks of the hostile Germans, planned a mutiny, being prompted and encouraged by Nigrinus, a tribune of a squadron of cavalry, a native of Mesopotamia. And having arranged the matter in secret conferences, and kept it close in profound silence, when they arrived at Aquileia, a city important from its situation and wealth, and fortified with strong walls, they suddenly closed the gates in a hostile manner, the native population, by whom the name of Constantius was still beloved, increasing the confusion and the terror. And having blockaded all the approaches, and armed the towers and battlements, they prepared measures to encounter the impending struggle, being in the mean time free and unrestrained. By this daring conduct they roused the Italian natives of the district to espouse the side of Constantius, who was still alive. XII. § 1. When Julian heard of this transaction, being then at Nissa, as he feared nothing unfriendly in his rear, and had read and heard that this city, though often besieged, had never been destroyed or taken, hastened the more eagerly to gain it, either by stratagem, or by some kind of flattery or other, before any more formidable event should arise.
