The Decline and Fall of the Roman Empire · Chapter 17 (5/9)

All the civil magistrates were drawn from the profession of the law. The celebrated Institutes of Justinian are addressed to the youth of his dominions, who had devoted themselves to the study of Roman jurisprudence; and the sovereign condescends to animate their diligence by the assurance that their skill and ability would in time be rewarded by an adequate share in the government of the republic.2053 The rudiments of this lucrative science were taught in all the considerable cities of the East and West; but the most famous school was that of Berytus,2054 on the coast of Phoenicia; which flourished above three centuries from the time of Alexander Severus, the author perhaps of an institution so advantageous to his native country. After a regular course of education, which lasted five years, the students dispersed themselves through the provinces, in search of fortune and honors; nor could they want an inexhaustible supply of business in a great empire already corrupted by the multiplicity of laws, of arts, and of vices. The court of the Praetorian prefect of the East could alone furnish employment for one hundred and fifty advocates, sixty-four of whom were distinguished by peculiar privileges, and two were annually chosen, with a salary of sixty pounds of gold, to defend the causes of the treasury. The first experiment was made of their judicial talents, by appointing them to act occasionally as assessors to the magistrates; from thence they were often raised to preside in the tribunals before which they had pleaded. They obtained the government of a province; and, by the aid of merit, of reputation, or of favor, they ascended, by successive steps, to the illustrious dignities of the state.2055 In the practice of the bar, these men had considered reason as the instrument of dispute; they interpreted the laws according to the dictates of private interest, and the same pernicious habits might still adhere to their characters in the public administration of the state. The honor of a liberal profession has indeed been vindicated by ancient and modern advocates, who have filled the most important stations with pure integrity and consummate wisdom; but in the decline of Roman jurisprudence, the ordinary promotion of lawyers was pregnant with mischief and disgrace. The noble art, which had once been preserved as the sacred inheritance of the patricians, was fallen into the hands of freedmen and plebeians,2056 who, with cunning rather than with skill, exercised a sordid and pernicious trade. Some of them procured admittance into families for the purpose of fomenting differences, of encouraging suits, and of preparing a harvest of gain for themselves or their brethren. Others, recluse in their chambers, maintained the dignity of legal professors by furnishing a rich client with subtleties to confound the plainest truths and with arguments to color the most unjustifiable pretensions. The splendid and popular class was composed of the advocates, who filled the Forum with the sound of their turgid and loquacious rhetoric. Careless of fame and of justice, they are described, for the most part, as ignorant and rapacious guides, who conducted their clients through a maze of expense, of delay, and of disappointment; from whence, after a tedious series of years, they were at length dismissed, when their patience and fortune were almost exhausted.2057

III. In the system of policy introduced by Augustus, the governors, those at least of the Imperial provinces, were invested with the full powers of the sovereign himself. Ministers of peace and war, the distribution of rewards and punishments depended on them alone, and they successively appeared on their tribunal in the robes of civil magistracy, and in complete armor at the head of the Roman legions.2058 The influence of the revenue, the authority of law, and the command of a military force concurred to render their power supreme and absolute; and whenever they were tempted to violate their allegiance, the loyal province which they involved in their rebellion was scarcely sensible of any change in its political state. From the time of Commodus to the reign of Constantine, near one hundred governors might be enumerated, who, with various success, erected the standard of revolt; and though the innocent were too often sacrificed, the guilty might be sometimes prevented, by the suspicious cruelty of their master.2059 To secure his throne and the public tranquillity from these formidable servants, Constantine resolved to divide the military from the civil administration, and to establish, as a permanent and professional distinction, a practice which had been adopted only as an occasional expedient. The supreme jurisdiction exercised by the Praetorian prefects over the armies of the empire was transferred to the two masters-general whom he instituted, the one for the cavalry, the other for the infantry; and though each of these illustrious officers was more peculiarly responsible for the discipline of those troops which were under his immediate inspection, they both indifferently commanded in the field the several bodies, whether of horse or foot, which were united in the same army.2060 Their number was soon doubled by the division of the East and West; and as separate generals of the same rank and title were appointed on the four important frontiers of the Rhine, of the Upper and the Lower Danube, and of the Euphrates, the defence of the Roman empire was at length committed to eight masters-general of the cavalry and infantry. Under their orders, thirty-five military commanders were stationed in the provinces: three in Britain, six in Gaul, one in Spain, one in Italy, five on the Upper, and four on the Lower Danube; in Asia, eight, three in Egypt, and four in Africa. The titles of counts, and dukes,2061 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 Palatines2062 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.2063 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.2064 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.

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.2065 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.2066 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.2067 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.2068 An effort so prodigious surpassed the wants of a more ancient, and the faculties of a later, period.
