The pacific exhortations of the bishop resulted in a truce, which gave time for Ricimer to engage the requisite number of Suevi and Burgundiones. Having done this he threw off the mask, and making the death of Aspar his plea, refused to acknowledge either Leo or Anthemius, proclaimed Olybrius, an enemy of his father-in-law, emperor, and commenced his march to Rome.

When the Roman governor of Gaul brought an army to support Anthemius, he was defeated and slain. Rome nevertheless held out bravely until reduced by famine when, with the exception of a few streets, occupied by his own adherents, Ricimer condemned it to be sacked. He then added to the list of emperors whom he had put to death the name of his own father-in-law, and died the same year (472).[d]

Whilst the vacant throne of Italy was abandoned to lawless barbarians, the election of a new colleague was seriously agitated in the council of Leo. The empress Verina, studious to promote the greatness of her own family, had married one of her nieces to Julius Nepos, who succeeded his uncle Marcellinus in the sovereignty of Dalmatia, a more solid possession than the title, which he was persuaded to accept, of emperor of the West.

But the measures of the Byzantine court were so languid and irresolute that many months elapsed after the death of Anthemius, and even of Olybrius, before their destined successor could show himself, with a respectable force, to his Italian subjects. During that interval, Glycerius, an obscure soldier, was invested with the purple by his patron Gundobald; but the Burgundionian prince was unable, or unwilling, to support his nomination by a civil war; the pursuits of domestic ambition recalled him beyond the Alps, and his client was permitted to exchange the Roman sceptre for the bishopric of Salona. After extinguishing such a competitor, the emperor Nepos was acknowledged by the senate, by the Italians, and by the provincials of Gaul; his moral virtues, and military talents, were loudly celebrated, and those who derived any private benefit from his government announced, in prophetic strains, the restoration of the public felicity. Their hopes (if such hopes had been entertained) were confounded within the term of a single year; and the treaty of peace, which ceded Auvergne to the Visigoths, is the only event of his short and inglorious reign.

[473-475 A.D.]

The most faithful subjects of Gaul were sacrificed by the Italian emperor to the hope of domestic security; but his repose was soon invaded by a furious sedition of the barbarian confederates, who, under the command of Orestes, their general, were in full march from Rome to Ravenna. Nepos trembled at their approach; and, instead of placing a just confidence in the strength of Ravenna, he hastily escaped to his ships and retired to his Dalmatian principality, on the opposite coast of the Adriatic. By this shameful abdication he protracted his life about five years, in a very ambiguous state between an emperor and an exile, till he was assassinated at Salona by the ungrateful Glycerius, who was translated, perhaps as the reward of his crime, to the archbishopric of Milan.

The nations who had asserted their independence after the death of Attila were established, by the right of possession or conquest, in the boundless countries to the north of the Danube, or in the Roman provinces between the river and the Alps. But the bravest of their youth enlisted in the army of confederates, who formed the defence and the terror of Italy; and in this promiscuous multitude the names of the Heruli, the Scyrri, the Alani, the Turcilingi, and the Rugi appear to have predominated.

The example of these warriors was imitated by Orestes, the son of Tatullus, and the father of the last Roman emperor of the West. Orestes, who has been already mentioned in this history, had never deserted his country. His birth and fortunes rendered him one of the most illustrious subjects of Pannonia. When that province was ceded to the Huns, he entered into the service of Attila, his lawful sovereign, obtained the office of his secretary, and was repeatedly sent ambassador to Constantinople, to represent the person and signify the commands of the imperious monarch. The death of that conqueror restored him to his freedom, and Orestes might honourably refuse either to follow the sons of Attila into the Scythian desert, or to obey the Ostrogoths, who had usurped the dominion of Pannonia. He preferred the service of the Italian princes, the successors of Valentinian; and as he possessed the qualifications of courage, industry, and experience, he advanced with rapid steps in the military profession, till he was elevated, by the favour of Nepos himself, to the dignities of patrician and master-general of the troops.

These troops had been long accustomed to reverence the character and authority of Orestes, who affected their manners, conversed with them in their own language, and was intimately connected with their national chieftains by long habits of familiarity and friendship. At his solicitation they rose in arms against the obscure Greek who presumed to claim their obedience; and when Orestes, from some secret motive, declined the purple, they consented, with the same facility, to acknowledge his son Augustulus as the emperor of the West. By the abdication of Nepos, Orestes had now attained the summit of his ambitious hopes; but he soon discovered, before the end of the first year, that the lessons of perjury and ingratitude which a rebel must inculcate will be retorted against himself; and that the precarious sovereign of Italy was only permitted to choose whether he would be the slave, or the victim, of his barbarian mercenaries. The dangerous alliance of these strangers had oppressed and insulted the last remains of Roman freedom and dignity. At each revolution, their pay and privileges were augmented; but their insolence increased in a still more extravagant degree. They envied the fortune of their brethren in Gaul, Spain, and Africa, whose victorious arms had acquired an independent and perpetual inheritance; and they insisted on their peremptory demand that a third part of the lands of Italy should be immediately divided among them.
