The same timid policy, of dividing whatever is united, of reducing whatever is eminent, of dreading every active power, and of expecting that the most feeble will prove the most obedient, seems to pervade the institutions of several princes, and particularly those of Constantine. The martial pride of the legions, whose victorious camps had so often been the scene of rebellion, was nourished by the memory of their past exploits, and the consciousness of their actual strength. As long as they maintained their ancient establishment of six thousand men, they subsisted, under the reign of Diocletian, each of them singly, a visible and important object in the military history of the Roman empire. A few years afterwards, these gigantic bodies were shrunk to a very diminutive size; and when seven legions, with some auxiliaries, defended the city of Amida against the Persians, the total garrison, with the inhabitants of both sexes, and the peasants of the deserted country, did not exceed the number of twenty thousand persons. From this fact, and from similar examples, there is reason to believe, that the constitution of the legionary troops, to which they partly owed their valor and discipline, was dissolved by Constantine; and that the bands of Roman infantry, which still assumed the same names and the same honors, consisted only of one thousand or fifteen hundred men. The conspiracy of so many separate detachments, each of which was awed by the sense of its own weakness, could easily be checked; and the successors of Constantine might indulge their love of ostentation, by issuing their orders to one hundred and thirty- two legions, inscribed on the muster-roll of their numerous armies. The remainder of their troops was distributed into several hundred cohorts of infantry, and squadrons of cavalry. Their arms, and titles, and ensigns, were calculated to inspire terror, and to display the variety of nations who marched under the Imperial standard. And not a vestige was left of that severe simplicity, which, in the ages of freedom and victory, had distinguished the line of battle of a Roman army from the confused host of an Asiatic monarch. A more particular enumeration, drawn from the Notitia, might exercise the diligence of an antiquary; but the historian will content himself with observing, that the number of permanent stations or garrisons established on the frontiers of the empire, amounted to five hundred and eighty-three; and that, under the successors of Constantine, the complete force of the military establishment was computed at six hundred and forty-five thousand soldiers. An effort so prodigious surpassed the wants of a more ancient, and the faculties of a later, period.

In the various states of society, armies are recruited from very different motives. Barbarians are urged by the love of war; the citizens of a free republic may be prompted by a principle of duty; the subjects, or at least the nobles, of a monarchy, are animated by a sentiment of honor; but the timid and luxurious inhabitants of a declining empire must be allured into the service by the hopes of profit, or compelled by the dread of punishment. The resources of the Roman treasury were exhausted by the increase of pay, by the repetition of donatives, and by the invention of new emolument and indulgences, which, in the opinion of the provincial youth might compensate the hardships and dangers of a military life. Yet, although the stature was lowered, although slaves, least by a tacit connivance, were indiscriminately received into the ranks, the insurmountable difficulty of procuring a regular and adequate supply of volunteers, obliged the emperors to adopt more effectual and coercive methods. The lands bestowed on the veterans, as the free reward of their valor were henceforward granted under a condition which contain the first rudiments of the feudal tenures; that their sons, who succeeded to the inheritance, should devote themselves to the profession of arms, as soon as they attained the age of manhood; and their cowardly refusal was punished by the lose of honor, of fortune, or even of life. But as the annual growth of the sons of the veterans bore a very small proportion to the demands of the service, levies of men were frequently required from the provinces, and every proprietor was obliged either to take up arms, or to procure a substitute, or to purchase his exemption by the payment of a heavy fine. The sum of forty-two pieces of gold, to which it was reduced, ascertains the exorbitant price of volunteers, and the reluctance with which the government admitted of this alterative. Such was the horror for the profession of a soldier, which had affected the minds of the degenerate Romans, that many of the youth of Italy and the provinces chose to cut off the fingers of their right hand, to escape from being pressed into the service; and this strange expedient was so commonly practised, as to deserve the severe animadversion of the laws, and a peculiar name in the Latin language.
