But even the omnipotence of Jovius and Herculius was insufficient to sustain the weight of the public administration. The prudence of Diocletian discovered that the empire, assailed on every side by the barbarians, required on every side the presence of a great army, and of an emperor. With this view, he resolved once more to divide his unwieldy power, and with the inferior title of Cæsars, [901] to confer on two generals of approved merit an unequal share of the sovereign authority. [10] Galerius, surnamed Armentarius, from his original profession of a herdsman, and Constantius, who from his pale complexion had acquired the denomination of Chlorus, [11] were the two persons invested with the second honors of the Imperial purple. In describing the country, extraction, and manners of Herculius, we have already delineated those of Galerius, who was often, and not improperly, styled the younger Maximian, though, in many instances both of virtue and ability, he appears to have possessed a manifest superiority over the elder. The birth of Constantius was less obscure than that of his colleagues. Eutropius, his father, was one of the most considerable nobles of Dardania, and his mother was the niece of the emperor Claudius. [12] Although the youth of Constantius had been spent in arms, he was endowed with a mild and amiable disposition, and the popular voice had long since acknowledged him worthy of the rank which he at last attained. To strengthen the bonds of political, by those of domestic, union, each of the emperors assumed the character of a father to one of the Cæsars, Diocletian to Galerius, and Maximian to Constantius; and each, obliging them to repudiate their former wives, bestowed his daughter in marriage or his adopted son. [13] These four princes distributed among themselves the wide extent of the Roman empire. The defence of Gaul, Spain, [14] and Britain, was intrusted to Constantius: Galerius was stationed on the banks of the Danube, as the safeguard of the Illyrian provinces. Italy and Africa were considered as the department of Maximian; and for his peculiar portion, Diocletian reserved Thrace, Egypt, and the rich countries of Asia. Every one was sovereign with his own jurisdiction; but their united authority extended over the whole monarchy, and each of them was prepared to assist his colleagues with his counsels or presence. The Cæsars, in their exalted rank, revered the majesty of the emperors, and the three younger princes invariably acknowledged, by their gratitude and obedience, the common parent of their fortunes. The suspicious jealousy of power found not any place among them; and the singular happiness of their union has been compared to a chorus of music, whose harmony was regulated and maintained by the skilful hand of the first artist.
