my arms." The authority of such a vision, or rather of the prince who alleged it, silenced every doubt, and excluded all negotiation. The ignominious terms of peace were rejected with disdain. One of the ambassadors of the tyrant was dismissed with the haughty answer of Constantius; his colleagues, as unworthy of the privileges of the law of nations, were put in irons; and the contending powers prepared to wage an implacable war.

Such was the conduct, and such perhaps was the duty, of the brother of Constans towards the perfidious usurper of Gaul. The situation and character of Vetranio admitted of milder measures; and the policy of the Eastern emperor was directed to disunite his antagonists, and to separate the forces of Illyricum from the cause of rebellion. It was an easy task to deceive the frankness and simplicity of Vetranio, who, fluctuating some time between the opposite views of honor and interest, displayed to the world the insincerity of his temper, and was insensibly engaged in the snares of an artful negotiation. Constantius acknowledged him as a legitimate and equal colleague in the empire, on condition that he would renounce his disgraceful alliance with Magnentius, and appoint a place of interview on the frontiers of their respective provinces; where they might pledge their friendship by mutual vows of fidelity, and regulate by common consent the future operations of the civil war. In consequence of this agreement, Vetranio advanced to the city of Sardica, at the head of twenty thousand horse, and of a more numerous body of infantry; a power so far superior to the forces of Constantius, that the Illyrian emperor appeared to command the life and fortunes of his rival, who, depending on the success of his private negotiations, had seduced the troops, and undermined the throne, of Vetranio. The chiefs, who had secretly embraced the party of Constantius, prepared in his favor a public spectacle, calculated to discover and inflame the passions of the multitude. The united armies were commanded to assemble in a large plain near the city. In the centre, according to the rules of ancient discipline, a military tribunal, or rather scaffold, was erected, from whence the emperors were accustomed, on solemn and important occasions, to harangue the troops. The well-ordered ranks of Romans and Barbarians, with drawn swords, or with erected spears, the squadrons of cavalry, and the cohorts of infantry, distinguished by the variety of their arms and ensigns, formed an immense circle round the tribunal; and the attentive silence which they preserved was sometimes interrupted by loud bursts of clamor or of applause. In the presence of this formidable assembly, the two emperors were called upon to explain the situation of public affairs: the precedency of rank was yielded to the royal birth of Constantius; and though he was indifferently skilled in the arts of rhetoric, he acquitted himself, under these difficult circumstances, with firmness, dexterity, and eloquence. The first part of his oration seemed to be pointed only against the tyrant of Gaul; but while he tragically lamented the cruel murder of Constans, he insinuated, that none, except a brother, could claim a right to the succession of his brother. He displayed, with some complacency, the glories of his Imperial race; and recalled to the memory of the troops the valor, the triumphs, the liberality of the great Constantine, to whose sons they had engaged their allegiance by an oath of fidelity, which the ingratitude of his most favored servants had tempted them to violate. The officers, who surrounded the tribunal, and were instructed to act their part in this extraordinary scene, confessed the irresistible power of reason and eloquence, by saluting the emperor Constantius as their lawful sovereign. The contagion of loyalty and repentance was communicated from rank to rank; till the plain of Sardica resounded with the universal acclamation of "Away with these upstart usurpers! Long life and victory to the son of Constantine! Under his banners alone we will fight and conquer." The shout of thousands, their menacing gestures, the fierce clashing of their arms, astonished and subdued the courage of Vetranio, who stood, amidst the defection of his followers, in anxious and silent suspense. Instead of embracing the last refuge of generous despair, he tamely submitted to his fate; and taking the diadem from his head, in the view of both armies fell prostrate at the feet of his conqueror. Constantius used his victory with prudence and moderation; and raising from the ground the aged suppliant, whom he affected to style by the endearing name of Father, he gave him his hand to descend from the throne. The city of Prusa was assigned for the exile or retirement of the abdicated monarch, who lived six years in the enjoyment of ease and affluence. He often expressed his grateful sense of the goodness of Constantius, and, with a very amiable simplicity, advised his benefactor to resign the sceptre of the world, and to seek for content (where alone it could be found) in the peaceful obscurity of a private condition.
