of counts, and dukes, by which they were properly distinguished, have obtained in modern languages so very different a sense, that the use of them may occasion some surprise. But it should be recollected, that the second of those appellations is only a corruption of the Latin word, which was indiscriminately applied to any military chief. All these provincial generals were therefore dukes; but no more than ten among them were dignified with the rank of counts or companions, a title of honor, or rather of favor, which had been recently invented in the court of Constantine. A gold belt was the ensign which distinguished the office of the counts and dukes; and besides their pay, they received a liberal allowance sufficient to maintain one hundred and ninety servants, and one hundred and fifty-eight horses. They were strictly prohibited from interfering in any matter which related to the administration of justice or the revenue; but the command which they exercised over the troops of their department, was independent of the authority of the magistrates. About the same time that Constantine gave a legal sanction to the ecclesiastical order, he instituted in the Roman empire the nice balance of the civil and the military powers. The emulation, and sometimes the discord, which reigned between two professions of opposite interests and incompatible manners, was productive of beneficial and of pernicious consequences. It was seldom to be expected that the general and the civil governor of a province should either conspire for the disturbance, or should unite for the service, of their country. While the one delayed to offer the assistance which the other disdained to solicit, the troops very frequently remained without orders or without supplies; the public safety was betrayed, and the defenceless subjects were left exposed to the fury of the Barbarians. The divided administration which had been formed by Constantine, relaxed the vigor of the state, while it secured the tranquillity of the monarch.

The memory of Constantine has been deservedly censured for another innovation, which corrupted military discipline and prepared the ruin of the empire. The nineteen years which preceded his final victory over Licinius, had been a period of license and intestine war. The rivals who contended for the possession of the Roman world, had withdrawn the greatest part of their forces from the guard of the general frontier; and the principal cities which formed the boundary of their respective dominions were filled with soldiers, who considered their countrymen as their most implacable enemies. After the use of these internal garrisons had ceased with the civil war, the conqueror wanted either wisdom or firmness to revive the severe discipline of Diocletian, and to suppress a fatal indulgence, which habit had endeared and almost confirmed to the military order. From the reign of Constantine, a popular and even legal distinction was admitted between the Palatines and the Borderers; the troops of the court, as they were improperly styled, and the troops of the frontier. The former, elevated by the superiority of their pay and privileges, were permitted, except in the extraordinary emergencies of war, to occupy their tranquil stations in the heart of the provinces. The most flourishing cities were oppressed by the intolerable weight of quarters. The soldiers insensibly forgot the virtues of their profession, and contracted only the vices of civil life. They were either degraded by the industry of mechanic trades, or enervated by the luxury of baths and theatres. They soon became careless of their martial exercises, curious in their diet and apparel; and while they inspired terror to the subjects of the empire, they trembled at the hostile approach of the Barbarians. The chain of fortifications which Diocletian and his colleagues had extended along the banks of the great rivers, was no longer maintained with the same care, or defended with the same vigilance. The numbers which still remained under the name of the troops of the frontier, might be sufficient for the ordinary defence; but their spirit was degraded by the humiliating reflection, that they who were exposed to the hardships and dangers of a perpetual warfare, were rewarded only with about two thirds of the pay and emoluments which were lavished on the troops of the court. Even the bands or legions that were raised the nearest to the level of those unworthy favorites, were in some measure disgraced by the title of honor which they were allowed to assume. It was in vain that Constantine repeated the most dreadful menaces of fire and sword against the Borderers who should dare desert their colors, to connive at the inroads of the Barbarians, or to participate in the spoil. The mischiefs which flow from injudicious counsels are seldom removed by the application of partial severities; and though succeeding princes labored to restore the strength and numbers of the frontier garrisons, the empire, till the last moment of its dissolution, continued to languish under the mortal wound which had been so rashly or so weakly inflicted by the hand of Constantine.
