The emperor presented Zenobia with an elegant villa at Tibur, or Tivoli, about twenty miles from the capital; the Syrian queen insensibly sunk into a Roman matron, her daughters married into noble families, and her race was not yet extinct in the fifth century.  Tetricus and his son were reinstated in their rank and fortunes. They erected on the Caelian hill a magnificent palace, and as soon as it was finished, invited Aurelian to supper. On his entrance, he was agreeably surprised with a picture which represented their singular history. They were delineated offering to the emperor a civic crown and the sceptre of Gaul, and again receiving at his hands the ornaments of the senatorial dignity. The father was afterwards invested with the government of Lucania,  and Aurelian, who soon admitted the abdicated monarch to his friendship and conversation, familiarly asked him, Whether it were not more desirable to administer a province of Italy, than to reign beyond the Alps. The son long continued a respectable member of the senate; nor was there any one of the Roman nobility more esteemed by Aurelian, as well as by his successors. 
[Footnote 82: Vopiscus in Hist. August. p. 199. Hieronym. in Chron. Prosper in Chron. Baronius supposes that Zenobius, bishop of Florence in the time of St. Ambrose, was of her family.]
[Footnote 83: Vopisc. in Hist. August. p. 222. Eutropius, ix. 13. Victor Junior. But Pollio, in Hist. August. p. 196, says, that Tetricus was made corrector of all Italy.]
[Footnote 84: Hist. August. p. 197.]
So long and so various was the pomp of Aurelian's triumph, that although it opened with the dawn of day, the slow majesty of the procession ascended not the Capitol before the ninth hour; and it was already dark when the emperor returned to the palace. The festival was protracted by theatrical representations, the games of the circus, the hunting of wild beasts, combats of gladiators, and naval engagements. Liberal donatives were distributed to the army and people, and several institutions, agreeable or beneficial to the city, contributed to perpetuate the glory of Aurelian. A considerable portion of his oriental spoils was consecrated to the gods of Rome; the Capitol, and every other temple, glittered with the offerings of his ostentatious piety; and the temple of the Sun alone received above fifteen thousand pounds of gold.  This last was a magnificent structure, erected by the emperor on the side of the Quirinal hill, and dedicated, soon after the triumph, to that deity whom Aurelian adored as the parent of his life and fortunes. His mother had been an inferior priestess in a chapel of the Sun; a peculiar devotion to the god of Light was a sentiment which the fortunate peasant imbibed in his infancy; and every step of his elevation, every victory of his reign, fortified superstition by gratitude. 
[Footnote 85: Vopiscus in Hist. August. 222. Zosimus, l. i. p. 56. He placed in it the images of Belus and of the Sun, which he had brought from Palmyra. It was dedicated in the fourth year of his reign, (Euseb in Chron.,) but was most assuredly begun immediately on his accession.]
[Footnote 86: See, in the Augustan History, p. 210, the omens of his fortune. His devotion to the Sun appears in his letters, on his medals, and is mentioned in the Caesars of Julian. Commentaire de Spanheim, p. 109.]
The arms of Aurelian had vanquished the foreign and domestic foes of the republic. We are assured, that, by his salutary rigor, crimes and factions, mischievous arts and pernicious connivance, the luxurious growth of a feeble and oppressive government, were eradicated throughout the Roman world.  But if we attentively reflect how much swifter is the progress of corruption than its cure, and if we remember that the years abandoned to public disorders exceeded the months allotted to the martial reign of Aurelian, we must confess that a few short intervals of peace were insufficient for the arduous work of reformation. Even his attempt to restore the integrity of the coin was opposed by a formidable insurrection. The emperor's vexation breaks out in one of his private letters. "Surely," says he, "the gods have decreed that my life should be a perpetual warfare. A sedition within the walls has just now given birth to a very serious civil war. The workmen of the mint, at the instigation of Felicissimus, a slave to whom I had intrusted an employment in the finances, have risen in rebellion. They are at length suppressed; but seven thousand of my soldiers have been slain in the contest, of those troops whose ordinary station is in Dacia, and the camps along the Danube."  Other writers, who confirm the same fact, add likewise, that it happened soon after Aurelian's triumph; that the decisive engagement was fought on the Caelian hill; that the workmen of the mint had adulterated the coin; and that the emperor restored the public credit, by delivering out good money in exchange for the bad, which the people was commanded to bring into the treasury. 
[Footnote 87: Vopiscus in Hist. August. p. 221.]
[Footnote 88: Hist. August. p. 222. Aurelian calls these soldiers Hiberi Riporiences Castriani, and Dacisci.]
[Footnote 89: Zosimus, l. i. p. 56. Eutropius, ix. 14. Aurel Victor.]
We might content ourselves with relating this extraordinary transaction, but we cannot dissemble how much in its present form it appears to us inconsistent and incredible. The debasement of the coin is indeed well suited to the administration of Gallienus; nor is it unlikely that the instruments of the corruption might dread the inflexible justice of Aurelian. But the guilt, as well as the profit, must have been confined to a very few; nor is it easy to conceive by what arts they could arm a people whom they had injured, against a monarch whom they had betrayed. We might naturally expect that such miscreants should have shared the public detestation with the informers and the other ministers of oppression; and that the reformation of the coin should have been an action equally popular with the destruction of those obsolete accounts, which by the emperor's order were burnt in the forum of Trajan.  In an age when the principles of commerce were so imperfectly understood, the most desirable end might perhaps be effected by harsh and injudicious means; but a temporary grievance of such a nature can scarcely excite and support a serious civil war. The repetition of intolerable taxes, imposed either on the land or on the necessaries of life, may at last provoke those who will not, or who cannot, relinquish their country. But the case is far otherwise in every operation which, by whatsoever expedients, restores the just value of money. The transient evil is soon obliterated by the permanent benefit, the loss is divided among multitudes; and if a few wealthy individuals experience a sensible diminution of treasure, with their riches, they at the same time lose the degree of weight and importance which they derived from the possession of them. However Aurelian might choose to disguise the real cause of the insurrection, his reformation of the coin could furnish only a faint pretence to a party already powerful and discontented. Rome, though deprived of freedom, was distracted by faction. The people, towards whom the emperor, himself a plebeian, always expressed a peculiar fondness, lived in perpetual dissension with the senate, the equestrian order, and the Praetorian guards.  Nothing less than the firm though secret conspiracy of those orders, of the authority of the first, the wealth of the second, and the arms of the third, could have displayed a strength capable of contending in battle with the veteran legions of the Danube, which, under the conduct of a martial sovereign, had achieved the conquest of the West and of the East.
[Footnote 90: Hist. August. p. 222. Aurel Victor.]
[Footnote 91: It already raged before Aurelian's return from Egypt. See Vipiscus, who quotes an original letter. Hist. August. p. 244.]
Whatever was the cause or the object of this rebellion, imputed with so little probability to the workmen of the mint, Aurelian used his victory with unrelenting rigor.  He was naturally of a severe disposition. A peasant and a soldier, his nerves yielded not easily to the impressions of sympathy, and he could sustain without emotion the sight of tortures and death. Trained from his earliest youth in the exercise of arms, he set too small a value on the life of a citizen, chastised by military execution the slightest offences, and transferred the stern discipline of the camp into the civil administration of the laws. His love of justice often became a blind and furious passion and whenever he deemed his own or the public safety endangered, he disregarded the rules of evidence, and the proportion of punishments. The unprovoked rebellion with which the Romans rewarded his services, exasperated his haughty spirit. The noblest families of the capital were involved in the guilt or suspicion of this dark conspiracy. A nasty spirit of revenge urged the bloody prosecution, and it proved fatal to one of the nephews of the emperor. The the executioners (if we may use the expression of a contemporary poet) were fatigued, the prisons were crowded, and the unhappy senate lamented the death or absence of its most illustrious members.  Nor was the pride of Aurelian less offensive to that assembly than his cruelty. Ignorant or impatient of the restraints of civil institutions, he disdained to hold his power by any other title than that of the sword, and governed by right of conquest an empire which he had saved and subdued. 
[Footnote 92: Vopiscus in Hist. August p. 222. The two Victors. Eutropius ix. 14. Zosimus (l. i. p. 43) mentions only three senators, and placed their death before the eastern war.]

[Footnote 94: According to the younger Victor, he sometimes wore the diadem, Deus and Dominus appear on his medals.]
It was observed by one of the most sagacious of the Roman princes, that the talents of his predecessor Aurelian were better suited to the command of an army, than to the government of an empire.  Conscious of the character in which nature and experience had enabled him to excel, he again took the field a few months after his triumph. It was expedient to exercise the restless temper of the legions in some foreign war, and the Persian monarch, exulting in the shame of Valerian, still braved with impunity the offended majesty of Rome. At the head of an army, less formidable by its numbers than by its discipline and valor, the emperor advanced as far as the Straits which divide Europe from Asia. He there experienced that the most absolute power is a weak defence against the effects of despair. He had threatened one of his secretaries who was accused of extortion; and it was known that he seldom threatened in vain. The last hope which remained for the criminal, was to involve some of the principal officers of the army in his danger, or at least in his fears. Artfully counterfeiting his master's hand, he showed them, in a long and bloody list, their own names devoted to death. Without suspecting or examining the fraud, they resolved to secure their lives by the murder of the emperor. On his march, between Byzanthium and Heraclea, Aurelian was suddenly attacked by the conspirators, whose stations gave them a right to surround his person, and after a short resistance, fell by the hand of Mucapor, a general whom he had always loved and trusted. He died regretted by the army, detested by the senate, but universally acknowledged as a warlike and fortunate prince, the useful, though severe reformer of a degenerate state. 
[Footnote 95: It was the observation of Dioclatian. See Vopiscus in Hist. August. p. 224.]

Chapter XII: Reigns Of Tacitus, Probus, Carus And His Sons.—Part I.
Conduct Of The Army And Senate After The Death Of Aurelian. —Reigns Of Tacitus, Probus, Carus, And His Sons.
Such was the unhappy condition of the Roman emperors, that, whatever might be their conduct, their fate was commonly the same. A life of pleasure or virtue, of severity or mildness, of indolence or glory, alike led to an untimely grave; and almost every reign is closed by the same disgusting repetition of treason and murder. The death of Aurelian, however, is remarkable by its extraordinary consequences. The legions admired, lamented, and revenged their victorious chief. The artifice of his perfidious secretary was discovered and punished.
The deluded conspirators attended the funeral of their injured sovereign, with sincere or well-feigned contrition, and submitted to the unanimous resolution of the military order, which was signified by the following epistle: "The brave and fortunate armies to the senate and people of Rome.—The crime of one man, and the error of many, have deprived us of the late emperor Aurelian. May it please you, venerable lords and fathers! to place him in the number of the gods, and to appoint a successor whom your judgment shall declare worthy of the Imperial purple! None of those whose guilt or misfortune have contributed to our loss, shall ever reign over us."  The Roman senators heard, without surprise, that another emperor had been assassinated in his camp; they secretly rejoiced in the fall of Aurelian; and, besides the recent notoriety of the facts, constantly draws his materials from the Journals of the Senate, and the but the modest and dutiful address of the legions, when it was communicated in full assembly by the consul, diffused the most pleasing astonishment. Such honors as fear and perhaps esteem could extort, they liberally poured forth on the memory of their deceased sovereign. Such acknowledgments as gratitude could inspire, they returned to the faithful armies of the republic, who entertained so just a sense of the legal authority of the senate in the choice of an emperor. Yet, notwithstanding this flattering appeal, the most prudent of the assembly declined exposing their safety and dignity to the caprice of an armed multitude. The strength of the legions was, indeed, a pledge of their sincerity, since those who may command are seldom reduced to the necessity of dissembling; but could it naturally be expected, that a hasty repentance would correct the inveterate habits of fourscore years? Should the soldiers relapse into their accustomed seditions, their insolence might disgrace the majesty of the senate, and prove fatal to the object of its choice. Motives like these dictated a decree, by which the election of a new emperor was referred to the suffrage of the military order.
[Footnote 1: Vopiscus in Hist. August. p. 222. Aurelius Victor mentions a formal deputation from the troops to the senate.]
The contention that ensued is one of the best attested, but most improbable events in the history of mankind.  The troops, as if satiated with the exercise of power, again conjured the senate to invest one of its own body with the Imperial purple. The senate still persisted in its refusal; the army in its request. The reciprocal offer was pressed and rejected at least three times, and, whilst the obstinate modesty of either party was resolved to receive a master from the hands of the other, eight months insensibly elapsed; an amazing period of tranquil anarchy, during which the Roman world remained without a sovereign, without a usurper, and without a sedition.  The generals and magistrates appointed by Aurelian continued to execute their ordinary functions; and it is observed, that a proconsul of Asia was the only considerable person removed from his office in the whole course of the interregnum.
[Footnote 2: Vopiscus, our principal authority, wrote at Rome, sixteen years only after the death of Aurelian; and, besides the recent notoriety of the facts, constantly draws his materials from the Journals of the Senate, and the original papers of the Ulpian library. Zosimus and Zonaras appear as ignorant of this transaction as they were in general of the Roman constitution.]
[Footnote 201: The interregnum could not be more than seven months; Aurelian was assassinated in the middle of March, the year of Rome 1028. Tacitus was elected the 25th September in the same year.—G.]
An event somewhat similar, but much less authentic, is supposed to have happened after the death of Romulus, who, in his life and character, bore some affinity with Aurelian. The throne was vacant during twelve months, till the election of a Sabine philosopher, and the public peace was guarded in the same manner, by the union of the several orders of the state. But, in the time of Numa and Romulus, the arms of the people were controlled by the authority of the Patricians; and the balance of freedom was easily preserved in a small and virtuous community.  The decline of the Roman state, far different from its infancy, was attended with every circumstance that could banish from an interregnum the prospect of obedience and harmony: an immense and tumultuous capital, a wide extent of empire, the servile equality of despotism, an army of four hundred thousand mercenaries, and the experience of frequent revolutions. Yet, notwithstanding all these temptations, the discipline and memory of Aurelian still restrained the seditious temper of the troops, as well as the fatal ambition of their leaders. The flower of the legions maintained their stations on the banks of the Bosphorus, and the Imperial standard awed the less powerful camps of Rome and of the provinces. A generous though transient enthusiasm seemed to animate the military order; and we may hope that a few real patriots cultivated the returning friendship of the army and the senate, as the only expedient capable of restoring the republic to its ancient beauty and vigor.
[Footnote 3: Liv. i. 17 Dionys. Halicarn. l. ii. p. 115. Plutarch in Numa, p. 60. The first of these writers relates the story like an orator, the second like a lawyer, and the third like a moralist, and none of them probably without some intermixture of fable.]
On the twenty-fifth of September, near eight months after the murder of Aurelian, the consul convoked an assembly of the senate, and reported the doubtful and dangerous situation of the empire. He slightly insinuated, that the precarious loyalty of the soldiers depended on the chance of every hour, and of every accident; but he represented, with the most convincing eloquence, the various dangers that might attend any further delay in the choice of an emperor. Intelligence, he said, was already received, that the Germans had passed the Rhine, and occupied some of the strongest and most opulent cities of Gaul. The ambition of the Persian king kept the East in perpetual alarms; Egypt, Africa, and Illyricum, were exposed to foreign and domestic arms, and the levity of Syria would prefer even a female sceptre to the sanctity of the Roman laws. The consul, then addressing himself to Tacitus, the first of the senators,  required his opinion on the important subject of a proper candidate for the vacant throne.
[Footnote 4: Vopiscus (in Hist. August p. 227) calls him "primae sententia consularis;" and soon afterwards Princeps senatus. It is natural to suppose, that the monarchs of Rome, disdaining that humble title, resigned it to the most ancient of the senators.]
If we can prefer personal merit to accidental greatness, we shall esteem the birth of Tacitus more truly noble than that of kings. He claimed his descent from the philosophic historian, whose writings will instruct the last generations of mankind.  The senator Tacitus was then seventy-five years of age.  The long period of his innocent life was adorned with wealth and honors. He had twice been invested with the consular dignity,  and enjoyed with elegance and sobriety his ample patrimony of between two and three millions sterling.  The experience of so many princes, whom he had esteemed or endured, from the vain follies of Elagabalus to the useful rigor of Aurelian, taught him to form a just estimate of the duties, the dangers, and the temptations of their sublime station. From the assiduous study of his immortal ancestor, he derived the knowledge of the Roman constitution, and of human nature.  The voice of the people had already named Tacitus as the citizen the most worthy of empire. The ungrateful rumor reached his ears, and induced him to seek the retirement of one of his villas in Campania. He had passed two months in the delightful privacy of Baiae, when he reluctantly obeyed the summons of the consul to resume his honorable place in the senate, and to assist the republic with his counsels on this important occasion.
[Footnote 5: The only objection to this genealogy is, that the historian was named Cornelius, the emperor, Claudius. But under the lower empire, surnames were extremely various and uncertain.]
[Footnote 6: Zonaras, l. xii. p. 637. The Alexandrian Chronicle, by an obvious mistake, transfers that age to Aurelian.]
[Footnote 7: In the year 273, he was ordinary consul. But he must have been Suffectus many years before, and most probably under Valerian.]
[Footnote 8: Bis millies octingenties. Vopiscus in Hist. August p. 229. This sum, according to the old standard, was equivalent to eight hundred and forty thousand Roman pounds of silver, each of the value of three pounds sterling. But in the age of Tacitus, the coin had lost much of its weight and purity.]
[Footnote 9: After his accession, he gave orders that ten copies of the historian should be annually transcribed and placed in the public libraries. The Roman libraries have long since perished, and the most valuable part of Tacitus was preserved in a single Ms., and discovered in a monastery of Westphalia. See Bayle, Dictionnaire, Art. Tacite, and Lipsius ad Annal. ii. 9.]
He arose to speak, when from every quarter of the house, he was saluted with the names of Augustus and emperor. "Tacitus Augustus, the gods preserve thee! we choose thee for our sovereign; to thy care we intrust the republic and the world. Accept the empire from the authority of the senate. It is due to thy rank, to thy conduct, to thy manners." As soon as the tumult of acclamations subsided, Tacitus attempted to decline the dangerous honor, and to express his wonder, that they should elect his age and infirmities to succeed the martial vigor of Aurelian. "Are these limbs, conscript fathers! fitted to sustain the weight of armor, or to practise the exercises of the camp? The variety of climates, and the hardships of a military life, would soon oppress a feeble constitution, which subsists only by the most tender management. My exhausted strength scarcely enables me to discharge the duty of a senator; how insufficient would it prove to the arduous labors of war and government! Can you hope, that the legions will respect a weak old man, whose days have been spent in the shade of peace and retirement? Can you desire that I should ever find reason to regret the favorable opinion of the senate?" 
[Footnote 10: Vopiscus in Hist. August. p. 227.]
The reluctance of Tacitus (and it might possibly be sincere) was encountered by the affectionate obstinacy of the senate. Five hundred voices repeated at once, in eloquent confusion, that the greatest of the Roman princes, Numa, Trajan, Hadrian, and the Antonines, had ascended the throne in a very advanced season of life; that the mind, not the body, a sovereign, not a soldier, was the object of their choice; and that they expected from him no more than to guide by his wisdom the valor of the legions. These pressing though tumultuary instances were seconded by a more regular oration of Metius Falconius, the next on the consular bench to Tacitus himself. He reminded the assembly of the evils which Rome had endured from the vices of headstrong and capricious youths, congratulated them on the election of a virtuous and experienced senator, and, with a manly, though perhaps a selfish, freedom, exhorted Tacitus to remember the reasons of his elevation, and to seek a successor, not in his own family, but in the republic. The speech of Falconius was enforced by a general acclamation. The emperor elect submitted to the authority of his country, and received the voluntary homage of his equals. The judgment of the senate was confirmed by the consent of the Roman people, and of the Praetorian guards. 
[Footnote 11: Hist. August. p. 228. Tacitus addressed the Praetorians by the appellation of sanctissimi milites, and the people by that of sacratissim. Quirites.]
The administration of Tacitus was not unworthy of his life and principles. A grateful servant of the senate, he considered that national council as the author, and himself as the subject, of the laws.  He studied to heal the wounds which Imperial pride, civil discord, and military violence, had inflicted on the constitution, and to restore, at least, the image of the ancient republic, as it had been preserved by the policy of Augustus, and the virtues of Trajan and the Antonines. It may not be useless to recapitulate some of the most important prerogatives which the senate appeared to have regained by the election of Tacitus.  1. To invest one of their body, under the title of emperor, with the general command of the armies, and the government of the frontier provinces. 2. To determine the list, or, as it was then styled, the College of Consuls. They were twelve in number, who, in successive pairs, each, during the space of two months, filled the year, and represented the dignity of that ancient office. The authority of the senate, in the nomination of the consuls, was exercised with such independent freedom, that no regard was paid to an irregular request of the emperor in favor of his brother Florianus. "The senate," exclaimed Tacitus, with the honest transport of a patriot, "understand the character of a prince whom they have chosen." 3. To appoint the proconsuls and presidents of the provinces, and to confer on all the magistrates their civil jurisdiction. 4. To receive appeals through the intermediate office of the praefect of the city from all the tribunals of the empire. 5. To give force and validity, by their decrees, to such as they should approve of the emperor's edicts. 6. To these several branches of authority we may add some inspection over the finances, since, even in the stern reign of Aurelian, it was in their power to divert a part of the revenue from the public service. 
[Footnote 12: In his manumissions he never exceeded the number of a hundred, as limited by the Caninian law, which was enacted under Augustus, and at length repealed by Justinian. See Casaubon ad locum Vopisci.]
[Footnote 13: See the lives of Tacitus, Florianus, and Probus, in the Augustan History; we may be well assured, that whatever the soldier gave the senator had already given.]
[Footnote 14: Vopiscus in Hist. August. p. 216. The passage is perfectly clear, both Casaubon and Salmasius wish to correct it.]
Circular epistles were sent, without delay, to all the principal cities of the empire, Treves, Milan, Aquileia, Thessalo nica, Corinth, Athens, Antioch, Alexandria, and Carthage, to claim their obedience, and to inform them of the happy revolution, which had restored the Roman senate to its ancient dignity. Two of these epistles are still extant. We likewise possess two very singular fragments of the private correspondence of the senators on this occasion. They discover the most excessive joy, and the most unbounded hopes. "Cast away your indolence," it is thus that one of the senators addresses his friend, "emerge from your retirements of Baiae and Puteoli. Give yourself to the city, to the senate. Rome flourishes, the whole republic flourishes. Thanks to the Roman army, to an army truly Roman; at length we have recovered our just authority, the end of all our desires. We hear appeals, we appoint proconsuls, we create emperors; perhaps too we may restrain them—to the wise a word is sufficient."  These lofty expectations were, however, soon disappointed; nor, indeed, was it possible that the armies and the provinces should long obey the luxurious and unwarlike nobles of Rome. On the slightest touch, the unsupported fabric of their pride and power fell to the ground. The expiring senate displayed a sudden lustre, blazed for a moment and was extinguished forever.
[Footnote 15: Vopiscus in Hist. August. p. 230, 232, 233. The senators celebrated the happy restoration with hecatombs and public rejoicings.]
All that had yet passed at Rome was no more than a theatrical representation, unless it was ratified by the more substantial power of the legions. Leaving the senators to enjoy their dream of freedom and ambition, Tacitus proceeded to the Thracian camp, and was there, by the Praetorian praefect, presented to the assembled troops, as the prince whom they themselves had demanded, and whom the senate had bestowed. As soon as the praefect was silent, the emperor addressed himself to the soldiers with eloquence and propriety. He gratified their avarice by a liberal distribution of treasure, under the names of pay and donative. He engaged their esteem by a spirited declaration, that although his age might disable him from the performance of military exploits, his counsels should never be unworthy of a Roman general, the successor of the brave Aurelian. 
[Footnote 16: Hist. August. p. 228.]
Whilst the deceased emperor was making preparations for a second expedition into the East, he had negotiated with the Alani,  a Scythian people, who pitched their tents in the neighborhood of the Lake Moeotis. 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. 
[Footnote 161: On the Alani, see ch. xxvi. note 55.—M.]
[Footnote 17: Vopiscus in Hist. August. p. 230. Zosimus, l. i. p. 57. Zonaras, l. xii. p. 637. Two passages in the life of Probus (p. 236, 238) convince me, that these Scythian invaders of Pontus were Alani. If we may believe Zosimus, (l. i. p. 58,) Florianus pursued them as far as the Cimmerian Bosphorus. But he had scarcely time for so long and difficult an expedition.]
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.  It is certain that their insolences was the cause of his death. He expired at Tyana in Cappadocia, after a reign of only six months and about twenty days. 
[Footnote 18: Eutropius and Aurelius Victor only say that he died; Victor Junior adds, that it was of a fever. Zosimus and Zonaras affirm, that he was killed by the soldiers. Vopiscus mentions both accounts, and seems to hesitate. Yet surely these jarring opinions are easily reconciled.]
[Footnote 19: According to the two Victors, he reigned exactly two hundred days.]
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. 
[Footnote 20: Hist. August, p. 231. Zosimus, l. i. p. 58, 59. Zonaras, l. xii. p. 637. Aurelius Victor says, that Probus assumed the empire in Illyricum; an opinion which (though adopted by a very learned man) would throw that period of history into inextricable confusion.]
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;  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. 
[Footnote 21: Hist. August. p. 229]
[Footnote 22: He was to send judges to the Parthians, Persians, and Sarmatians, a president to Taprobani, and a proconsul to the Roman island, (supposed by Casaubon and Salmasius to mean Britain.) Such a history as mine (says Vopiscus with proper modesty) will not subsist a thousand years, to expose or justify the prediction.]
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.  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 intrusted 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 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;  in the full possession of his fame, of the love of the army, and of a mature vigor of mind and body.
[Footnote 23: For the private life of Probus, see Vopiscus in Hist. August p. 234—237]
[Footnote 24: According to the Alexandrian chronicle, he was fifty at the time of his death.]
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."  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."  When this respectful epistle was read by the consul, the senators were unable to disguise their satisfaction, that Probus should condescend thus numbly 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,  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.  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.

Chapter XII: Reigns Of Tacitus, Probus, Carus And His Sons.—Part II.
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,  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.  He attacked the Isaurians in their mountains, besieged and took several of their strongest castles,  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,  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 intrusted 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. 
[Footnote 29: The date and duration of the reign of Probus are very correctly ascertained by Cardinal Noris in his learned work, De Epochis Syro-Macedonum, p. 96—105. A passage of Eusebius connects the second year of Probus with the aeras of several of the Syrian cities.]
[Footnote 30: Vopiscus in Hist. August. p. 239.]
[Footnote 31: Zosimus (l. i. p. 62—65) tells us a very long and trifling story of Lycius, the Isaurian robber.]
[Footnote 32: Zosim. l. i. p. 65. Vopiscus in Hist. August. p. 239, 240. But it seems incredible that the defeat of the savages of Aethiopia could affect the Persian monarch.]
[Footnote 33: Besides these well-known chiefs, several others are named by Vopiscus, (Hist. August. p. 241,) whose actions have not reached knowledge.]
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.  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.  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.  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.  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;  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."  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.  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.
[Footnote 34: See the Caesars of Julian, and Hist. August. p. 238, 240, 241.]
[Footnote 341: It was only under the emperors Diocletian and Maximian, that the Burgundians, in concert with the Alemanni, invaded the interior of Gaul; under the reign of Probus, they did no more than pass the river which separated them from the Roman Empire: they were repelled. Gatterer presumes that this river was the Danube; a passage in Zosimus appears to me rather to indicate the Rhine. Zos. l. i. p. 37, edit H. Etienne, 1581.—G. On the origin of the Burgundians may be consulted Malte Brun, Geogr vi. p. 396, (edit. 1831,) who observes that all the remains of the Burgundian language indicate that they spoke a Gothic dialect.—M.]
[Footnote 35: Zosimus, l. i. p. 62. Hist. August. p. 240. But the latter supposes the punishment inflicted with the consent of their kings: if so, it was partial, like the offence.]
[Footnote 36: See Cluver. Germania Antiqua, l. iii. Ptolemy places in their country the city of Calisia, probably Calish in Silesia. * Note: Luden (vol ii. 501) supposes that these have been erroneously identified with the Lygii of Tacitus. Perhaps one fertile source of mistakes has been, that the Romans have turned appellations into national names. Malte Brun observes of the Lygii, "that their name appears Sclavonian, and signifies 'inhabitants of plains;' they are probably the Lieches of the middle ages, and the ancestors of the Poles. We find among the Arii the worship of the two twin gods known in the Sclavian mythology." Malte Brun, vol. i. p. 278, (edit. 1831.)—M. But compare Schafarik, Slawische Alterthumer, 1, p. 406. They were of German or Keltish descent, occupying the Wendish (or Slavian) district, Luhy.—M. 1845.]

[Footnote 38: Tacit. Germania, (c. 43.)]
[Footnote 39: Vopiscus in Hist. August. p. 238]
Since the expedition of Maximin, the Roman generals had confined their ambition to a defensive war against the nations of Germany, who perpetually pressed on the frontiers of the empire. The more daring Probus pursued his Gallic victories, passed the Rhine, and displayed his invincible eagles on the banks of the Elbe and the Necker. He was fully convinced that nothing could reconcile the minds of the barbarians to peace, unless they experienced, in their own country, the calamities of war. Germany, exhausted by the ill success of the last emigration, was astonished by his presence. Nine of the most considerable princes repaired to his camp, and fell prostrate at his feet. Such a treaty was humbly received by the Germans, as it pleased the conqueror to dictate. He exacted a strict restitution of the effects and captives which they had carried away from the provinces; and obliged their own magistrates to punish the more obstinate robbers who presumed to detain any part of the spoil. A considerable tribute of corn, cattle, and horses, the only wealth of barbarians, was reserved for the use of the garrisons which Probus established on the limits of their territory. He even entertained some thoughts of compelling the Germans to relinquish the exercise of arms, and to trust their differences to the justice, their safety to the power, of Rome. To accomplish these salutary ends, the constant residence of an Imperial governor, supported by a numerous army, was indispensably requisite. Probus therefore judged it more expedient to defer the execution of so great a design; which was indeed rather of specious than solid utility.  Had Germany been reduced into the state of a province, the Romans, with immense labor and expense, would have acquired only a more extensive boundary to defend against the fiercer and more active barbarians of Scythia.
[Footnote 40: Hist. August. 238, 239. Vopiscus quotes a letter from the emperor to the senate, in which he mentions his design of reducing Germany into a province.]
Instead of reducing the warlike natives of Germany to the condition of subjects, Probus contented himself with the humble expedient of raising a bulwark against their inroads. The country which now forms the circle of Swabia had been left desert in the age of Augustus by the emigration of its ancient inhabitants.  The fertility of the soil soon attracted a new colony from the adjacent provinces of Gaul. Crowds of adventurers, of a roving temper and of desperate fortunes, occupied the doubtful possession, and acknowledged, by the payment of tithes the majesty of the empire.  To protect these new subjects, a line of frontier garrisons was gradually extended from the Rhine to the Danube. About the reign of Hadrian, when that mode of defence began to be practised, these garrisons were connected and covered by a strong intrenchment of trees and palisades. In the place of so rude a bulwark, the emperor Probus constructed a stone wall of a considerable height, and strengthened it by towers at convenient distances. From the neighborhood of Newstadt and Ratisbon on the Danube, it stretched across hills, valleys, rivers, and morasses, as far as Wimpfen on the Necker, and at length terminated on the banks of the Rhine, after a winding course of near two hundred miles.  This important barrier, uniting the two mighty streams that protected the provinces of Europe, seemed to fill up the vacant space through which the barbarians, and particularly the Alemanni, could penetrate with the greatest facility into the heart of the empire. But the experience of the world, from China to Britain, has exposed the vain attempt of fortifying any extensive tract of country.  An active enemy, who can select and vary his points of attack, must, in the end, discover some feeble spot, on some unguarded moment. The strength, as well as the attention, of the defenders is divided; and such are the blind effects of terror on the firmest troops, that a line broken in a single place is almost instantly deserted. The fate of the wall which Probus erected may confirm the general observation. Within a few years after his death, it was overthrown by the Alemanni. Its scattered ruins, universally ascribed to the power of the Daemon, now serve only to excite the wonder of the Swabian peasant.
[Footnote 41: Strabo, l. vii. According to Valleius Paterculus, (ii. 108,) Maroboduus led his Marcomanni into Bohemia; Cluverius (German. Antiq. iii. 8) proves that it was from Swabia.]

The anonymous author is well acquainted with the globe in general, and with Germany in particular: with regard to the latter, he quotes a work of M. Hanselman; but he seems to confound the wall of Probus, designed against the Alemanni, with the fortification of the Mattiaci, constructed in the neighborhood of Frankfort against the Catti. * Note: De Pauw is well known to have been the author of this work, as of the Recherches sur les Americains before quoted. The judgment of M. Remusat on this writer is in a very different, I fear a juster tone.

Sur les l angues Tartares, p. 231.—M.]
Among the useful conditions of peace imposed by Probus on the vanquished nations of Germany, was the obligation of supplying the Roman army with sixteen thousand recruits, the bravest and most robust of their youth. The emperor dispersed them through all the provinces, and distributed this dangerous reenforcement, in small bands of fifty or sixty each, among the national troops; judiciously observing, that the aid which the republic derived from the barbarians should be felt but not seen.  Their aid was now become necessary. The feeble elegance of Italy and the internal provinces could no longer support the weight of arms. The hardy frontiers of the Rhine and Danube still produced minds and bodies equal to the labors of the camp; but a perpetual series of wars had gradually diminished their numbers. The infrequency of marriage, and the ruin of agriculture, affected the principles of population, and not only destroyed the strength of the present, but intercepted the hope of future, generations. The wisdom of Probus embraced a great and beneficial plan of replenishing the exhausted frontiers, by new colonies of captive or fugitive barbarians, on whom he bestowed lands, cattle, instruments of husbandry, and every encouragement that might engage them to educate a race of soldiers for the service of the republic. Into Britain, and most probably into Cambridgeshire,  he transported a considerable body of Vandals. The impossibility of an escape reconciled them to their situation, and in the subsequent troubles of that island, they approved themselves the most faithful servants of the state.  Great numbers of Franks and Gepidae were settled on the banks of the Danube and the Rhine. A hundred thousand Bastarnae, expelled from their own country, cheerfully accepted an establishment in Thrace, and soon imbibed the manners and sentiments of Roman subjects.  But the expectations of Probus were too often disappointed. The impatience and idleness of the barbarians could ill brook the slow labors of agriculture. Their unconquerable love of freedom, rising against despotism, provoked them into hasty rebellions, alike fatal to themselves and to the provinces;  nor could these artificial supplies, however repeated by succeeding emperors, restore the important limit of Gaul and Illyricum to its ancient and native vigor.
[Footnote 45: He distributed about fifty or sixty barbarians to a Numerus, as it was then called, a corps with whose established number we are not exactly acquainted.]
[Footnote 46: Camden's Britannia, Introduction, p. 136; but he speaks from a very doubtful conjecture.]
[Footnote 47: Zosimus, l. i. p. 62. According to Vopiscus, another body of Vandals was less faithful.]
[Footnote 48: Hist. August. p. 240. They were probably expelled by the Goths. Zosim. l. i. p. 66.]
[Footnote 49: Hist. August. p. 240.]
Of all the barbarians who abandoned their new settlements, and disturbed the public tranquillity, a very small number returned to their own country. For a short season they might wander in arms through the empire; but in the end they were surely destroyed by the power of a warlike emperor. The successful rashness of a party of Franks was attended, however, with such memorable consequences, that it ought not to be passed unnoticed. They had been established by Probus, on the sea-coast of Pontus, with a view of strengthening the frontier against the inroads of the Alani. A fleet stationed in one of the harbors of the Euxine fell into the hands of the Franks; and they resolved, through unknown seas, to explore their way from the mouth of the Phasis to that of the Rhine. They easily escaped through the Bosphorus and the Hellespont, and cruising along the Mediterranean, indulged their appetite for revenge and plunder by frequent descents on the unsuspecting shores of Asia, Greece, and Africa. The opulent city of Syracuse, in whose port the natives of Athens and Carthage had formerly been sunk, was sacked by a handful of barbarians, who massacred the greatest part of the trembling inhabitants. From the Island of Sicily, the Franks proceeded to the columns of Hercules, trusted themselves to the ocean, coasted round Spain and Gaul, and steering their triumphant course through the British Channel, at length finished their surprising voyage, by landing in safety on the Batavian or Frisian shores.  The example of their success, instructing their countrymen to conceive the advantages and to despise the dangers of the sea, pointed out to their enterprising spirit a new road to wealth and glory.
[Footnote 50: Panegyr. Vet. v. 18. Zosimus, l. i. p. 66.]
Notwithstanding the vigilance and activity of Probus, it was almost impossible that he could at once contain in obedience every part of his wide-extended dominions. The barbarians, who broke their chains, had seized the favorable opportunity of a domestic war. When the emperor marched to the relief of Gaul, he devolved the command of the East on Saturninus. That general, a man of merit and experience, was driven into rebellion by the absence of his sovereign, the levity of the Alexandrian people, the pressing instances of his friends, and his own fears; but from the moment of his elevation, he never entertained a hope of empire, or even of life. "Alas!" he said, "the republic has lost a useful servant, and the rashness of an hour has destroyed the services of many years. You know not," continued he, "the misery of sovereign power; a sword is perpetually suspended over our head. We dread our very guards, we distrust our companions. The choice of action or of repose is no longer in our disposition, nor is there any age, or character, or conduct, that can protect us from the censure of envy. In thus exalting me to the throne, you have doomed me to a life of cares, and to an untimely fate. The only consolation which remains is, the assurance that I shall not fall alone."  But as the former part of his prediction was verified by the victory, so the latter was disappointed by the clemency of Probus. That amiable prince attempted even to save the unhappy Saturninus from the fury of the soldiers. He had more than once solicited the usurper himself to place some confidence in the mercy of a sovereign who so highly esteemed his character, that he had punished, as a malicious informer, the first who related the improbable news of his disaffection.  Saturninus might, perhaps, have embraced the generous offer, had he not been restrained by the obstinate distrust of his adherents. Their guilt was deeper, and their hopes more sanguine, than those of their experienced leader.
[Footnote 51: Vopiscus in Hist. August. p. 245, 246. The unfortunate orator had studied rhetoric at Carthage; and was therefore more probably a Moor (Zosim. l. i. p. 60) than a Gaul, as Vopiscus calls him.]
[Footnote 52: Zonaras, l. xii. p. 638.]
The revolt of Saturninus was scarcely extinguished in the East, before new troubles were excited in the West, by the rebellion of Bonosus and Proculus, in Gaul. The most distinguished merit of those two officers was their respective prowess, of the one in the combats of Bacchus, of the other in those of Venus,  yet neither of them was destitute of courage and capacity, and both sustained, with honor, the august character which the fear of punishment had engaged them to assume, till they sunk at length beneath the superior genius of Probus. He used the victory with his accustomed moderation, and spared the fortune, as well as the lives of their innocent families. 
[Footnote 53: A very surprising instance is recorded of the prowess of Procufus. He had taken one hundred Sarmatian virgins. The rest of the story he must relate in his own language: "Ex his una necte decem inivi; omnes tamen, quod in me erat, mulieres intra dies quindecim reddidi." Vopiscus in Hist. August. p. 246.]
[Footnote 54: Proculus, who was a native of Albengue, on the Genoese coast armed two thousand of his own slaves. His riches were great, but they were acquired by robbery. It was afterwards a saying of his family, sibi non placere esse vel principes vel latrones. Vopiscus in Hist. August. p. 247.]
The arms of Probus had now suppressed all the foreign and domestic enemies of the state. His mild but steady administration confirmed the reestablishment of the public tranquillity; nor was there left in the provinces a hostile barbarian, a tyrant, or even a robber, to revive the memory of past disorders. It was time that the emperor should revisit Rome, and celebrate his own glory and the general happiness. The triumph due to the valor of Probus was conducted with a magnificence suitable to his fortune, and the people who had so lately admired the trophies of Aurelian, gazed with equal pleasure on those of his heroic successor.  We cannot, on this occasion, forget the desperate courage of about fourscore gladiators, reserved, with near six hundred others, for the inhuman sports of the amphitheatre. Disdaining to shed their blood for the amusement of the populace, they killed their keepers, broke from the place of their confinement, and filled the streets of Rome with blood and confusion. After an obstinate resistance, they were overpowered and cut in pieces by the regular forces; but they obtained at least an honorable death, and the satisfaction of a just revenge. 
[Footnote 55: Hist. August. p. 240.]
[Footnote 56: Zosim. l. i. p. 66.]
The military discipline which reigned in the camps of Probus was less cruel than that of Aurelian, but it was equally rigid and exact. The latter had punished the irregularities of the soldiers with unrelenting severity, the former prevented them by employing the legions in constant and useful labors. When Probus commanded in Egypt, he executed many considerable works for the splendor and benefit of that rich country. The navigation of the Nile, so important to Rome itself, was improved; and temples, buildings, porticos, and palaces were constructed by the hands of the soldiers, who acted by turns as architects, as engineers, and as husbandmen.  It was reported of Hannibal, that in order to preserve his troops from the dangerous temptations of idleness, he had obliged them to form large plantations of olive-trees along the coast of Africa.  From a similar principle, Probus exercised his legions in covering with rich vineyards the hills of Gaul and Pannonia, and two considerable spots are described, which were entirely dug and planted by military labor.  One of these, known under the name of Mount Almo, was situated near Sirmium, the country where Probus was born, for which he ever retained a partial affection, and whose gratitude he endeavored to secure, by converting into tillage a large and unhealthy tract of marshy ground. An army thus employed constituted perhaps the most useful, as well as the bravest, portion of Roman subjects.
[Footnote 57: Hist. August. p. 236.]
[Footnote 58: Aurel. Victor. in Prob. But the policy of Hannibal, unnoticed by any more ancient writer, is irreconcilable with the history of his life. He left Africa when he was nine years old, returned to it when he was forty-five, and immediately lost his army in the decisive battle of Zama. Livilus, xxx. 37.]
[Footnote 59: Hist. August. p. 240. Eutrop. ix. 17. Aurel. Victor. in Prob. Victor Junior. He revoked the prohibition of Domitian, and granted a general permission of planting vines to the Gauls, the Britons, and the Pannonians.]
But in the prosecution of a favorite scheme, the best of men, satisfied with the rectitude of their intentions, are subject to forget the bounds of moderation; nor did Probus himself sufficiently consult the patience and disposition of his fierce legionaries.  The dangers of the military profession seem only to be compensated by a life of pleasure and idleness; but if the duties of the soldier are incessantly aggravated by the labors of the peasant, he will at last sink under the intolerable burden, or shake it off with indignation. The imprudence of Probus is said to have inflamed the discontent of his troops. More attentive to the interests of mankind than to those of the army, he expressed the vain hope, that, by the establishment of universal peace, he should soon abolish the necessity of a standing and mercenary force.  The unguarded expression proved fatal to him. In one of the hottest days of summer, as he severely urged the unwholesome labor of draining the marshes of Sirmium, the soldiers, impatient of fatigue, on a sudden threw down their tools, grasped their arms, and broke out into a furious mutiny. The emperor, conscious of his danger, took refuge in a lofty tower, constructed for the purpose of surveying the progress of the work.  The tower was instantly forced, and a thousand swords were plunged at once into the bosom of the unfortunate Probus. The rage of the troops subsided as soon as it had been gratified. They then lamented their fatal rashness, forgot the severity of the emperor, whom they had massacred, and hastened to perpetuate, by an honorable monument, the memory of his virtues and victories. 
[Footnote 60: Julian bestows a severe, and indeed excessive, censure on the rigor of Probus, who, as he thinks, almost deserved his fate.]
[Footnote 61: Vopiscus in Hist. August. p. 241. He lavishes on this idle hope a large stock of very foolish eloquence.]
[Footnote 62: Turris ferrata. It seems to have been a movable tower, and cased with iron.]
[Footnote 63: Probus, et vere probus situs est; Victor omnium gentium Barbararum; victor etiam tyrannorum.]
When the legions had indulged their grief and repentance for the death of Probus, their unanimous consent declared Carus, his Praetorian praefect, the most deserving of the Imperial throne. Every circumstance that relates to this prince appears of a mixed and doubtful nature. He gloried in the title of Roman Citizen; and affected to compare the purity of his blood with the foreign and even barbarous origin of the preceding emperors; yet the most inquisitive of his contemporaries, very far from admitting his claim, have variously deduced his own birth, or that of his parents, from Illyricum, from Gaul, or from Africa.  Though a soldier, he had received a learned education; though a senator, he was invested with the first dignity of the army; and in an age when the civil and military professions began to be irrecoverably separated from each other, they were united in the person of Carus. Notwithstanding the severe justice which he exercised against the assassins of Probus, to whose favor and esteem he was highly indebted, he could not escape the suspicion of being accessory to a deed from whence he derived the principal advantage. He enjoyed, at least, before his elevation, an acknowledged character of virtue and abilities;  but his austere temper insensibly degenerated into moroseness and cruelty; and the imperfect writers of his life almost hesitate whether they shall not rank him in the number of Roman tyrants.  When Carus assumed the purple, he was about sixty years of age, and his two sons, Carinus and Numerian had already attained the season of manhood. 
[Footnote 64: Yet all this may be conciliated. He was born at Narbonne in Illyricum, confounded by Eutropius with the more famous city of that name in Gaul. His father might be an African, and his mother a noble Roman. Carus himself was educated in the capital. See Scaliger Animadversion. ad Euseb. Chron. p. 241.]
[Footnote 65: Probus had requested of the senate an equestrian statue and a marble palace, at the public expense, as a just recompense of the singular merit of Carus. Vopiscus in Hist. August. p. 249.]

The authority of the senate expired with Probus; nor was the repentance of the soldiers displayed by the same dutiful regard for the civil power, which they had testified after the unfortunate death of Aurelian. The election of Carus was decided without expecting the approbation of the senate, and the new emperor contented himself with announcing, in a cold and stately epistle, that he had ascended the vacant throne.  A behavior so very opposite to that of his amiable predecessor afforded no favorable presage of the new reign: and the Romans, deprived of power and freedom, asserted their privilege of licentious murmurs.  The voice of congratulation and flattery was not, however, silent; and we may still peruse, with pleasure and contempt, an eclogue, which was composed on the accession of the emperor Carus. Two shepherds, avoiding the noontide heat, retire into the cave of Faunus. On a spreading beech they discover some recent characters. The rural deity had described, in prophetic verses, the felicity promised to the empire under the reign of so great a prince. Faunus hails the approach of that hero, who, receiving on his shoulders the sinking weight of the Roman world, shall extinguish war and faction, and once again restore the innocence and security of the golden age.

It is more than probable, that these elegant trifles never reached the ears of a veteran general, who, with the consent of the legions, was preparing to execute the long-suspended design of the Persian war. Before his departure for this distant expedition, Carus conferred on his two sons, Carinus and Numerian, the title of Caesar, and investing the former with almost an equal share of the Imperial power, directed the young prince, first to suppress some troubles which had arisen in Gaul, and afterwards to fix the seat of his residence at Rome, and to assume the government of the Western provinces.  The safety of Illyricum was confirmed by a memorable defeat of the Sarmatians; sixteen thousand of those barbarians remained on the field of battle, and the number of captives amounted to twenty thousand. The old emperor, animated with the fame and prospect of victory, pursued his march, in the midst of winter, through the countries of Thrace and Asia Minor, and at length, with his younger son, Numerian, arrived on the confines of the Persian monarchy. There, encamping on the summit of a lofty mountain, he pointed out to his troops the opulence and luxury of the enemy whom they were about to invade.
[Footnote 71: Hist. August. p. 353. Eutropius, ix. 18. Pagi. Annal.]
The successor of Artaxerxes,  Varanes, or Bahram, though he had subdued the Segestans, one of the most warlike nations of Upper Asia,  was alarmed at the approach of the Romans, and endeavored to retard their progress by a negotiation of peace. 
His ambassadors entered the camp about sunset, at the time when the troops were satisfying their hunger with a frugal repast. The Persians expressed their desire of being introduced to the presence of the Roman emperor. They were at length conducted to a soldier, who was seated on the grass. A piece of stale bacon and a few hard peas composed his supper. A coarse woollen garment of purple was the only circumstance that announced his dignity. The conference was conducted with the same disregard of courtly elegance. Carus, taking off a cap which he wore to conceal his baldness, assured the ambassadors, that, unless their master acknowledged the superiority of Rome, he would speedily render Persia as naked of trees as his own head was destitute of hair.  Notwithstanding some traces of art and preparation, we may discover in this scene the manners of Carus, and the severe simplicity which the martial princes, who succeeded Gallienus, had already restored in the Roman camps. The ministers of the Great King trembled and retired.

[Footnote 72: Agathias, l. iv. p. 135. We find one of his sayings in the Bibliotheque Orientale of M. d'Herbelot. "The definition of humanity includes all other virtues."]
[Footnote 721: The manner in which his life was saved by the Chief Pontiff from a conspiracy of his nobles, is as remarkable as his saying. "By the advice (of the Pontiff) all the nobles absented themselves from court. The king wandered through his palace alone. He saw no one; all was silence around. He became alarmed and distressed. At last the Chief Pontiff appeared, and bowed his head in apparent misery, but spoke not a word. The king entreated him to declare what had happened. The virtuous man boldly related all that had passed, and conjured Bahram, in the name of his glorious ancestors, to change his conduct and save himself from destruction. The king was much moved, professed himself most penitent, and said he was resolved his future life should prove his sincerity. The overjoyed High Priest, delighted at this success, made a signal, at which all the nobles and attendants were in an instant, as if by magic, in their usual places. The monarch now perceived that only one opinion prevailed on his past conduct. He repeated therefore to his nobles all he had said to the Chief Pontiff, and his future reign was unstained by cruelty or oppression." Malcolm's Persia,—M.]
[Footnote 73: Synesius tells this story of Carinus; and it is much more natural to understand it of Carus, than (as Petavius and Tillemont choose to do) of Probus.]
The threats of Carus were not without effect. He ravaged Mesopotamia, cut in pieces whatever opposed his passage, made himself master of the great cities of Seleucia and Ctesiphon, (which seemed to have surrendered without resistance,) and carried his victorious arms beyond the Tigris.  He had seized the favorable moment for an invasion. The Persian councils were distracted by domestic factions, and the greater part of their forces were detained on the frontiers of India. Rome and the East received with transports the news of such important advantages. Flattery and hope painted, in the most lively colors, the fall of Persia, the conquest of Arabia, the submission of Egypt, and a lasting deliverance from the inroads of the Scythian nations.  But the reign of Carus was destined to expose the vanity of predictions. They were scarcely uttered before they were contradicted by his death; an event attended with such ambiguous circumstances, that it may be related in a letter from his own secretary to the praefect of the city. "Carus," says he, "our dearest emperor, was confined by sickness to his bed, when a furious tempest arose in the camp. The darkness which overspread the sky was so thick, that we could no longer distinguish each other; and the incessant flashes of lightning took from us the knowledge of all that passed in the general confusion. Immediately after the most violent clap of thunder, we heard a sudden cry that the emperor was dead; and it soon appeared, that his chamberlains, in a rage of grief, had set fire to the royal pavilion; a circumstance which gave rise to the report that Carus was killed by lightning. But, as far as we have been able to investigate the truth, his death was the natural effect of his disorder." 
[Footnote 74: Vopiscus in Hist. August. p. 250. Eutropius, ix. 18. The two Victors.]
[Footnote 75: To the Persian victory of Carus I refer the dialogue of the Philopatris, which has so long been an object of dispute among the learned. But to explain and justify my opinion, would require a dissertation. Note: Niebuhr, in the new edition of the Byzantine Historians, (vol. x.) has boldly assigned the Philopatris to the tenth century, and to the reign of Nicephorus Phocas. An opinion so decisively pronounced by Niebuhr and favorably received by Hase, the learned editor of Leo Diaconus, commands respectful consideration. But the whole tone of the work appears to me altogether inconsistent with any period in which philosophy did not stand, as it were, on some ground of equality with Christianity. The doctrine of the Trinity is sarcastically introduced rather as the strange doctrine of a new religion, than the established tenet of a faith universally prevalent. The argument, adopted from Solanus, concerning the formula of the procession of the Holy Ghost, is utterly worthless, as it is a mere quotation in the words of the Gospel of St. John, xv. 26. The only argument of any value is the historic one, from the allusion to the recent violation of many virgins in the Island of Crete. But neither is the language of Niebuhr quite accurate, nor his reference to the Acroases of Theodosius satisfactory. When, then, could this occurrence take place? Why not in the devastation of the island by the Gothic pirates, during the reign of Claudius. Hist. Aug. in Claud. p. 814. edit. Var. Lugd. Bat 1661.—M.]
[Footnote 76: Hist. August. p. 250. Yet Eutropius, Festus, Rufus, the two Victors, Jerome, Sidonius Apollinaris, Syncellus, and Zonaras, all ascribe the death of Carus to lightning.]
Chapter XII: Reigns Of Tacitus, Probus, Carus And His Sons.—Part III.
The vacancy of the throne was not productive of any disturbance. The ambition of the aspiring generals was checked by their natural fears, and young Numerian, with his absent brother Carinus, were unanimously acknowledged as Roman emperors.
The public expected that the successor of Carus would pursue his father's footsteps, and, without allowing the Persians to recover from their consternation, would advance sword in hand to the palaces of Susa and Ecbatana.  But the legions, however strong in numbers and discipline, were dismayed by the most abject superstition. Notwithstanding all the arts that were practised to disguise the manner of the late emperor's death, it was found impossible to remove the opinion of the multitude, and the power of opinion is irresistible. Places or persons struck with lightning were considered by the ancients with pious horror, as singularly devoted to the wrath of Heaven.  An oracle was remembered, which marked the River Tigris as the fatal boundary of the Roman arms. The troops, terrified with the fate of Carus and with their own danger, called aloud on young Numerian to obey the will of the gods, and to lead them away from this inauspicious scene of war. The feeble emperor was unable to subdue their obstinate prejudice, and the Persians wondered at the unexpected retreat of a victorious enemy. 
[Footnote 77: See Nemesian. Cynegeticon, v. 71, &c.]
[Footnote 78: See Festus and his commentators on the word Scribonianum. Places struck by lightning were surrounded with a wall; things were buried with mysterious ceremony.]
[Footnote 79: Vopiscus in Hist. August. p. 250. Aurelius Victor seems to believe the prediction, and to approve the retreat.]
The intelligence of the mysterious fate of the late emperor was soon carried from the frontiers of Persia to Rome; and the senate, as well as the provinces, congratulated the accession of the sons of Carus. These fortunate youths were strangers, however, to that conscious superiority, either of birth or of merit, which can alone render the possession of a throne easy, and as it were natural. Born and educated in a private station, the election of their father raised them at once to the rank of princes; and his death, which happened about sixteen months afterwards, left them the unexpected legacy of a vast empire. To sustain with temper this rapid elevation, an uncommon share of virtue and prudence was requisite; and Carinus, the elder of the brothers, was more than commonly deficient in those qualities. In the Gallic war he discovered some degree of personal courage;  but from the moment of his arrival at Rome, he abandoned himself to the luxury of the capital, and to the abuse of his fortune. He was soft, yet cruel; devoted to pleasure, but destitute of taste; and though exquisitely susceptible of vanity, indifferent to the public esteem. In the course of a few months, he successively married and divorced nine wives, most of whom he left pregnant; and notwithstanding this legal inconstancy, found time to indulge such a variety of irregular appetites, as brought dishonor on himself and on the noblest houses of Rome. He beheld with inveterate hatred all those who might remember his former obscurity, or censure his present conduct. He banished, or put to death, the friends and counsellors whom his father had placed about him, to guide his inexperienced youth; and he persecuted with the meanest revenge his school-fellows and companions who had not sufficiently respected the latent majesty of the emperor.
With the senators, Carinus affected a lofty and regal demeanor, frequently declaring, that he designed to distribute their estates among the populace of Rome. From the dregs of that populace he selected his favorites, and even his ministers. The palace, and even the Imperial table, were filled with singers, dancers, prostitutes, and all the various retinue of vice and folly. One of his doorkeepers  he intrusted with the government of the city. In the room of the Praetorian praefect, whom he put to death, Carinus substituted one of the ministers of his looser pleasures. Another, who possessed the same, or even a more infamous, title to favor, was invested with the consulship. A confidential secretary, who had acquired uncommon skill in the art of forgery, delivered the indolent emperor, with his own consent from the irksome duty of signing his name.
