He managed the finances so well, that, without oppressive taxes or unjust confiscations, he always had means for the construction of roads, bridges, and aqueducts; for loans to persons whose estates had been injured by earthquakes or tempests; and for public buildings in Rome and all the provinces. The Ulpian Library and the great “Forum of Trajan,” for the better transaction of public business, among many other useful and elegant works, bore witness to his liberality. The reign of Trajan was a literary epoch only second to that of Augustus. The great historian Tacitus, the younger Pliny, Plutarch, Sueto´nius, and Epicte´tus, the slave-philosopher, were all living at this time.
202. Augustus had enjoined his heirs to regard the Rhine, the Danube, and the Euphrates as the limits of their dominion. Trajan, however, desiring to throw off the disgraceful tribute which Domitian had promised to the Dacians, made war twice against their king, Deceb´alus. He was completely victorious; the king was slain, and his country became a Roman province guarded by colonies and forts. On his return, A. D. 105, Trajan celebrated a triumph, and exhibited games during 123 days. It is said that 11,000 wild beasts were slaughtered in these spectacles, and that 10,000 gladiators, mostly Dacian prisoners, killed each other “to make a Roman holiday.”
In the later years of this reign, the Roman and the Parthian empires came into conflict for the control of Armenia. Trajan quickly reduced the latter country to a Roman province, and, in subsequent campaigns, he wrested from the Parthians the ancient countries of Mesopotamia and Assyria. Trajan died in Cilicia, A. D. 117. His ashes were conveyed to Rome in a golden urn, and placed under the column which bears his name.
203. Ha´drian began his reign by surrendering the Asiatic conquests of Trajan. During the twenty years of almost unbroken peace which marked his administration, Hadrian visited the remotest corners of his empire, studied the wants and interests of his people, and tried impartially to secure the best good of all. York in England, Athens, Antioch, and Alexandria shared with Rome the honors of an imperial capital; and each had its part of those great architectural works which, in some cases, still exist to commemorate the glory of Hadrian. A revolt of the Jews, A. D. 131-135, was ended with the banishment from Palestine of the last remnants of their race. A Roman colony, Æ´lia Capitolina, was founded upon the site of Jerusalem, to which the Christians, expelled by Titus, were freely admitted with the first of their Gentile bishops. Of all the benefits which Hadrian conferred upon the empire, the greatest, perhaps, was his choice of a successor.
204. T. Aurelius Antoni´nus came to the throne A. D. 138. His uneventful reign presents the rare example in Roman annals of twenty-three years’ undisturbed tranquillity, and is a striking example of the truth of the saying, “Happy is the people that has no history.” The happiness of his great family, for so he regarded his subjects, was the ruling purpose of his life. In Britain, the Roman boundary was pushed to its farthest northern limit during this reign, and guarded by the “Wall of Antoninus,” extending from the Frith of Forth to the Clyde.
Marcus Aurelius, the nephew of Hadrian, who, together with L. Verus, had been adopted by Antoninus, assumed the latter’s name[78] with his crown. He resembled his adoptive father in his love of religion, justice, and peace; but his reign was far less happy, owing to calamities which were beyond his power to avert. The barbarians north of the Danube began to be crowded by a new and great immigration from the steppes of Asia. The Scythic hordes, broken up from their ancient seats, we know not by what impulse or necessity, had thrown themselves upon the Germans, and these were driven across the Roman frontier, even into Italy, which they ravaged as far as Aquilei´a, on the Adriatic. The two emperors proceeded against them. Verus died in the Venetian country A. D. 169, but Aurelius remained at his post on the Danube, summer and winter, for three years. He gained a great victory over the Quadi, A. D. 174. A sudden storm, occurring during the battle, decided the result. The pagans attributed it to an intervention of Jupiter Pluvius; but the Christians, to the prayers of Christian soldiers in the “Thundering Legion.”
During the first years of the reign of Aurelius, the Parthians made a formidable attack upon the eastern provinces, destroyed an entire legion, and ravaged all Syria. The general Avidius Cassius, being sent against them as the lieutenant of Verus, more than made good the Roman losses, for he extended the boundary of the empire again to the Tigris. But after the death of Verus, Cassius was led to proclaim himself emperor, and gained possession of most of the Asiatic provinces. Before Aurelius could arrive in the East, the rebel chief was slain by his own officers, after a reign of three months. Aurelius caused his papers to be burnt without reading them, and suffered no man to be punished for his part in the rebellion.
The elevation and self-control which distinguished the emperor were owing, in great measure, to the Stoic philosophy which he studied from his twelfth year. The only blot on his character is the persecution of the Christians, which was doubtless instigated by the harsh and arrogant Stoics who surrounded him. Justin Martyr at Rome, the venerable Polycarp at Smyrna, and multitudes of less illustrious disciples at Vienna and Lyons, suffered death for their fidelity to their religion, A. D. 167-177. Marcus Aurelius died in Pannonia, A. D. 180.
205. Deceived by the youthful promise of his only son, Aurelius had associated Com´modus with him in the government at the age of fifteen. If the young prince could have enjoyed many years of training under the wise and virtuous care of his father, he might indeed have become all that was hoped of him. But the untimely death of the good Aurelius left his son at seventeen a weak, self-indulgent youth, easily controled by worthless associates. For three years the government continued in the course which Aurelius had marked out for it. But, A. D. 183, a plot for the murder of Commodus was detected, and many senators were believed to be involved. His revengeful nature, stimulated by fear, now made him a monster of tyranny. His only use of imperial power was to issue warrants for the death of all whom he suspected. Vain of his strength and skill, he assumed the name of the Roman Hercules, and exhibited himself in the amphitheater as a marksman and gladiator. At last, some of the intended victims of his proscriptions avoided their own destruction by strangling him in his bed-chamber, after he had reigned twelve years and nine months, A. D. 192.
206. The decline of the empire, which had been delayed by the Five Good Emperors—Nerva, Trajan, Hadrian, and the two Antonines—proceeded with frightful rapidity under Commodus. The armies in the provinces, tired of discipline, broke up into petty bands which robbed and murdered on their own account. One historian tells us that Peren´nis, the prætorian præfect, was deposed and slain, with his wife and children, upon the demand of 1,500 insurgent soldiers who had marched unresisted from Britain to Rome. Society was as thoroughly demoralized as the army. Except among the despised and persecuted Christians, purity of life was scarcely to be found. Poverty was creeping upon the nations through the decline of industry, but luxury and self-indulgence were more wildly excessive than ever.
