In the tide of emigration which impetuously rolled from the confines of China to those of Germany, the most powerful and populous tribes may commonly be found on the verge of the Roman provinces. The accumulated weight was sustained for a while by artificial barriers; and the easy condescension of the emperors invited, without satisfying, the insolent demands of the barbarians, who had acquired an eager appetite for the luxuries of civilised life. The Hungarians, who ambitiously insert the name of Attila among their native kings, may affirm with truth that the hordes which were subject to his uncle Roas (Ruas) or Rugilas had formed their encampments within the limits of modern Hungary, in a fertile country which liberally supplied the wants of a nation of hunters and shepherds. In this advantageous situation, Rugilas and his valiant brothers, who continually added to their power and reputation, commanded the alternative of peace or war with the two empires. His alliance with the Romans of the West was cemented by his personal friendship for the great Aëtius, who was always secure of finding, in the barbarian camp, a hospitable reception and a powerful support. At his solicitation, and in the name of Joannes the usurper, sixty thousand Huns advanced to the confines of Italy; their march and their retreat were alike expensive to the state; and the grateful policy of Aëtius abandoned the possession of Pannonia to his faithful confederates. The Romans of the East were not less apprehensive of the arms of Rugilas, which threatened the provinces, or even the capital. Some ecclesiastical historians have destroyed the barbarians with lightning and pestilence; but Theodosius was reduced to the more humble expedient of stipulating an annual payment of 350 pounds of gold, and of disguising this dishonourable tribute by the title of general, which the king of the Huns condescended to accept. The public tranquillity was frequently interrupted by the fierce impatience of the barbarians and the perfidious intrigues of the Byzantine court. Four dependent nations, among whom we may distinguish the Bavarians, disclaimed the sovereignty of the Huns; and their revolt was encouraged and protected by a Roman alliance, till the just claims and formidable power of Rugilas were effectually urged by the voice of Eslaw his ambassador. Peace was the unanimous wish of the senate. Their decree was ratified by the emperor; and two ambassadors were named, Plinthas, a general of Scythian extraction but of consular rank, and the quæstor Epigenes, a wise and experienced statesman, who was recommended to that office by his ambitious colleague.
