The Decline and Fall of the Roman Empire · Chapter 12 (2/5)

Whilst the deceased emperor was making preparations for a second expedition into the East, he had negotiated with the Alani,1155 a Scythian people, who pitched their tents in the neighborhood of the lake Maeotis. Those barbarians, allured by presents and subsidies, had promised to invade Persia with a numerous body of light cavalry. They were faithful to their engagements; but when they arrived on the Roman frontier, Aurelian was already dead, the design of the Persian war was at least suspended, and the generals, who, during the interregnum, exercised a doubtful authority, were unprepared either to receive or to oppose them. Provoked by such treatment, which they considered as trifling and perfidious, the Alani had recourse to their own valor for their payment and revenge; and as they moved with the usual swiftness of Tartars, they had soon spread themselves over the provinces of Pontus, Cappadocia, Cilicia, and Galatia. The legions, who from the opposite shores of the Bosphorus could almost distinguish the flames of the cities and villages, impatiently urged their general to lead them against the invaders. The conduct of Tacitus was suitable to his age and station. He convinced the barbarians of the faith, as well as the power, of the empire. Great numbers of the Alani, appeased by the punctual discharge of the engagements which Aurelian had contracted with them, relinquished their booty and captives, and quietly retreated to their own deserts beyond the Phasis. Against the remainder, who refused peace, the Roman emperor waged, in person, a successful war. Seconded by an army of brave and experienced veterans, in a few weeks he delivered the provinces of Asia from the terror of the Scythian invasion.1156

But the glory and life of Tacitus were of short duration. Transported, in the depth of winter, from the soft retirement of Campania to the foot of Mount Caucasus, he sunk under the unaccustomed hardships of a military life. The fatigues of the body were aggravated by the cares of the mind. For a while, the angry and selfish passions of the soldiers had been suspended by the enthusiasm of public virtue. They soon broke out with redoubled violence, and raged in the camp, and even in the tent of the aged emperor. His mild and amiable character served only to inspire contempt, and he was incessantly tormented with factions which he could not assuage, and by demands which it was impossible to satisfy. Whatever flattering expectations he had conceived of reconciling the public disorders, Tacitus soon was convinced that the licentiousness of the army disdained the feeble restraint of laws, and his last hour was hastened by anguish and disappointment. It may be doubtful whether the soldiers imbrued their hands in the blood of this innocent prince.1157 AD 276-04-12 It is certain that their insolence was the cause of his death. He expired at Tyana in Cappadocia, after a reign of only six months and about twenty days.1158

The eyes of Tacitus were scarcely closed before his brother Florianus showed himself unworthy to reign, by the hasty usurpation of the purple, without expecting the approbation of the senate. The reverence for the Roman constitution, which yet influenced the camp and the provinces, was sufficiently strong to dispose them to censure, but not to provoke them to oppose, the precipitate ambition of Florianus. The discontent would have evaporated in idle murmurs, had not the general of the East, the heroic Probus, boldly declared himself the avenger of the senate. The contest, however, was still unequal; nor could the most able leader, at the head of the effeminate troops of Egypt and Syria, encounter, with any hopes of victory, the legions of Europe, whose irresistible strength appeared to support the brother of Tacitus. But the fortune and activity of Probus triumphed over every obstacle. The hardy veterans of his rival, accustomed to cold climates, sickened and consumed away in the sultry heats of Cilicia, where the summer proved remarkably unwholesome. Their numbers were diminished by frequent desertion, the passes of the mountains were feebly defended; Tarsus opened its gates, and the soldiers of Florianus, when they had permitted him to enjoy the Imperial title about three months, delivered the empire from civil war by the easy sacrifice of a prince whom they despised.1159

The perpetual revolutions of the throne had so perfectly erased every notion of hereditary title, that the family of an unfortunate emperor was incapable of exciting the jealousy of his successors. The children of Tacitus and Florianus were permitted to descend into a private station, and to mingle with the general mass of the people. Their poverty indeed became an additional safeguard to their innocence. When Tacitus was elected by the senate, he resigned his ample patrimony to the public service;1160 an act of generosity specious in appearance, but which evidently disclosed his intention of transmitting the empire to his descendants. The only consolation of their fallen state was the remembrance of transient greatness, and a distant hope, the child of a flattering prophecy, that, at the end of a thousand years, a monarch of the race of Tacitus should arise, the protector of the senate, the restorer of Rome, and the conqueror of the whole earth.1161

The peasants of Illyricum, who had already given Claudius and Aurelian to the sinking empire, had an equal right to glory in the elevation of Probus.1162 Above twenty years before, the emperor Valerian, with his usual penetration, had discovered the rising merit of the young soldier, on whom he conferred the rank of tribune long before the age prescribed by the military regulations. The tribune soon justified his choice by a victory over a great body of Sarmatians, in which he saved the life of a near relation of Valerian; and deserved to receive from the emperor’s hand the collars, bracelets, spears, and banners, the mural and the civic crown, and all the honorable rewards reserved by ancient Rome for successful valor. The third, and afterwards the tenth, legion were entrusted to the command of Probus, who, in every step of his promotion, showed himself superior to the station which he filled. Africa and Pontus, the Rhine, the Danube, the Euphrates, and the Nile, by turns afforded him the most splendid occasions of displaying his personal prowess and his conduct in war. Aurelian was indebted to him for the conquest of Egypt, and still more indebted for the honest courage with which he often checked the cruelty of his master. Tacitus, who desired by the abilities of his generals to supply his own deficiency of military talents, named him commander-in-chief of all the eastern provinces, with five times the usual salary, the promise of the consulship, and the hope of a triumph. When Probus ascended the Imperial throne, he was about forty-four years of age;1163 in the full possession of his fame, of the love of the army, and of a mature vigor of mind and body.

His acknowledge merit, and the success of his arms against Florianus, left him without an enemy or a competitor. Yet, if we may credit his own professions, very far from being desirous of the empire, he had accepted it with the most sincere reluctance. “But it is no longer in my power,” says Probus, in a private letter, “to lay down a title so full of envy and of danger. I must continue to personate the character which the soldiers have imposed upon me.”1164 His dutiful address to the senate displayed the sentiments, or at least the language, of a Roman patriot:

“When you elected one of your order, conscript fathers! to succeed the Emperor Aurelian, you acted in a manner suitable to your justice and wisdom. For you are the legal sovereigns of the world, and the power which you derive from your ancestors will descend to your posterity. Happy would it have been, if Florianus, instead of usurping the purple of his brother, like a private inheritance, had expected what your majesty might determine, either in his favor or in that of other person. The prudent soldiers have punished his rashness. To me they have offered the title of Augustus. But I submit to your clemency my pretensions and my merits.”1165

AD 276-08-03 When this respectful epistle was read by the consul, the senators were unable to disguise their satisfaction that Probus should condescend thus humbly to solicit a sceptre which he already possessed. They celebrated with the warmest gratitude his virtues, his exploits, and above all his moderation. A decree immediately passed, without a dissenting voice, to ratify the election of the eastern armies, and to confer on their chief all the several branches of the Imperial dignity: the names of Caesar and Augustus, the title of Father of his country, the right of making in the same day three motions in the senate,1166 the office of Pontifex Maximus, the tribunitian power, and the proconsular command; a mode of investiture, which, though it seemed to multiply the authority of the emperor, expressed the constitution of the ancient republic. The reign of Probus corresponded with this fair beginning. The senate was permitted to direct the civil administration of the empire. Their faithful general asserted the honor of the Roman arms, and often laid at their feet crowns of gold and barbaric trophies, the fruits of his numerous victories.1167 Yet, whilst he gratified their vanity, he must secretly have despised their indolence and weakness. Though it was every moment in their power to repeal the disgraceful edict of Gallienus, the proud successors of the Scipios patiently acquiesced in their exclusion from all military employments. They soon experienced that those who refuse the sword must renounce the sceptre.

The strength of Aurelian had crushed on every side the enemies of Rome. After his death they seemed to revive, with an increase of fury and of numbers. They were again vanquished by the active vigor of Probus, who, in a short reign of about six years,1168 equalled the fame of ancient heroes, and restored peace and order to every province of the Roman world. The dangerous frontier of Rhaetia he so firmly secured, that he left it without the suspicion of an enemy. He broke the wandering power of the Sarmatian tribes, and by the terror of his arms compelled those barbarians to relinquish their spoil. The Gothic nation courted the alliance of so warlike an emperor.1169 He attacked the Isaurians in their mountains, besieged and took several of their strongest castles,1170 and flattered himself that he had forever suppressed a domestic foe whose independence so deeply wounded the majesty of the empire. The troubles excited by the usurper Firmus in the Upper Egypt had never been perfectly appeased, and the cities of Ptolemais and Coptos, fortified by the alliance of the Blemmyes, still maintained an obscure rebellion. The chastisement of those cities, and of their auxiliaries the savages of the South, is said to have alarmed the court of Persia,1171 and the Great King sued in vain for the friendship of Probus. Most of the exploits which distinguished his reign were achieved by the personal valor and conduct of the emperor, insomuch that the writer of his life expresses some amazement how, in so short a time, a single man could be present in so many distant wars. The remaining actions he entrusted to the care of his lieutenants, the judicious choice of whom forms no inconsiderable part of his glory. Carus, Diocletian, Maximian, Constantius, Galerius, Asclepiodatus, Annibalianus, and a crowd of other chiefs, who afterwards ascended or supported the throne, were trained to arms in the severe school of Aurelian and Probus.1172

AD 277 But the most important service which Probus rendered to the republic was the deliverance of Gaul, and the recovery of seventy flourishing cities oppressed by the barbarians of Germany, who, since the death of Aurelian, had ravaged that great province with impunity.1173 Among the various multitude of those fierce invaders we may distinguish, with some degree of clearness, three great armies, or rather nations, successively vanquished by the valor of Probus. He drove back the Franks into their morasses; a descriptive circumstance from whence we may infer that the confederacy known by the manly appellation of Free already occupied the flat maritime country, intersected and almost overflown by the stagnating waters of the Rhine, and that several tribes of the Frisians and Batavians had acceded to their alliance. He vanquished the Burgundians, a considerable people of the Vandalic race.1174 They had wandered in quest of booty from the banks of the Oder to those of the Seine. They esteemed themselves sufficiently fortunate to purchase, by the restitution of all their booty, the permission of an undisturbed retreat. They attempted to elude that article of the treaty. Their punishment was immediate and terrible.1175 But of all the invaders of Gaul, the most formidable were the Lygians, a distant people who reigned over a wide domain on the frontiers of Poland and Silesia.1176 In the Lygian nation, the Arii held the first rank by their numbers and fierceness. “The Arii” (it is thus that they are described by the energy of Tacitus) “study to improve by art and circumstances the innate terrors of their barbarism. Their shields are black, their bodies are painted black. They choose for the combat the darkest hour of the night. Their host advances, covered as it were with a funeral shade;1177 nor do they often find an enemy capable of sustaining so strange and infernal an aspect. Of all our senses, the eyes are the first vanquished in battle.”1178 Yet the arms and discipline of the Romans easily discomfited these horrid phantoms. The Lygii were defeated in a general engagement, and Semno, the most renowned of their chiefs, fell alive into the hands of Probus. That prudent emperor, unwilling to reduce a brave people to despair, granted them an honorable capitulation, and permitted them to return in safety to their native country. But the losses which they suffered in the march, the battle, and the retreat, broke the power of the nation: nor is the Lygian name ever repeated in the history either of Germany or of the empire. The deliverance of Gaul is reported to have cost the lives of four hundred thousand of the invaders; a work of labor to the Romans, and of expense to the emperor, who gave a piece of gold for the head of every barbarian.1179 But, as the fame of warriors is built on the destruction of human kind, we may naturally suspect that the sanguinary account was multiplied by the avarice of the soldiers, and accepted without any very severe examination by the liberal vanity of Probus.
