CHAPTER XXIX.
THE ROMAN EMPIRE.
(From 31 B.C. to A.D. 180.)
Reign of Augustus Cæsar (31 B.C. to A.D. 14).—The hundred years of strife which ended with the battle of Actium left the Roman republic, exhausted and helpless, in the hands of one wise enough and strong enough to remould its crumbling fragments in such a manner that the state, which seemed ready to fall to pieces, might prolong its existence for another five hundred years. It was a great work thus to create anew, as it were, out of anarchy and chaos, a political fabric that should exhibit such elements of perpetuity and strength. "The establishment of the Roman empire," says Merivale, "was, after all, the greatest political work that any human being ever wrought. The achievements of Alexander, of Cæsar, of Charlemagne, of Napoleon, are not to be compared with it for a moment."
The government which Octavius established was a monarchy in fact, but a republic in form. Mindful of the fate of Julius Cæsar, who fell because he gave the lovers of the republic reason to think that he coveted the title of king, Octavius carefully veiled his really absolute sovereignty under the forms of the old republican state. The Senate still existed; but so completely subjected were its members to the influence of the conqueror that the only function it really exercised was the conferring of honors and titles and abject flatteries upon its master. All the republican officials remained; but Octavius absorbed and exercised their chief powers and functions. He had the powers of consul, tribune, censor, and Pontifex Maximus. All the republican magistrates—the consuls, the tribunes, the prætors—were elected as usual; but they were simply the nominees and creatures of the emperor. They were ​the effigies and figure-heads to delude the people into believing that the republic still existed. Never did a people seem more content with the shadow after the loss of the substance.
The Senate, acting under the inspiration of Octavius, withheld from him the title of king, which ever since the expulsion of the Tarquins, five centuries before this time, had been intolerable to the people; but they conferred upon him the titles of Imperator and Augustus, the latter having been hitherto sacred to the gods. The sixth month of the Roman year was called Augustus (whence our August) in his honor, an act in imitation of that by which the preceding month had been given the name of Julius in honor of Julius Cæsar.
The domains over which Augustus held sway were imperial in magnitude. They stretched from the Atlantic to the Euphrates, and upon the north were hemmed by the forests of Germany and the bleak steppes of Scythia, and were bordered on the south by ​the sands of the African desert and the dreary wastes of Arabia, which seemed the boundaries set by nature to dominion in those directions. Within these limits were crowded more than 100,000,000 people, embracing every conceivable condition and variety in race and culture, from the roughbarbarians of Gaul to the refined voluptuary of the East.
Octavius was the first to moderate the ambition of the Romans, and to council them not to attempt to conquer any more of the world, but rather to devote their energies to the work of consolidating the domains already acquired. He saw the dangers that would attend any further extension of the boundaries of the state.
The reign of Augustus lasted forty- four years, from 31 B.C. to A.D. 14. It embraced the most splendid period of the annals of Rome. Under the patronage of the emperor, and that of his favorite minister Maecenas, poets and writers flourished and made this the "golden age " of Latin literature. During this reign Virgil composed his immortal epic of the Æneid, and Horace his famous odes; while Livy wrote his inimitable history, and Ovid his Metamorphoses. Many who lamented the fall of the republic sought solace in the pursuit of letters; and in this they were encouraged by Augustus, as it gave occupation to many restless spirits that would otherwise have been engaged in political intrigues against his government.
Augustus was also a munificent patron of architecture and art. He adorned the capital with many splendid structures. Said he proudly, "I found Rome a city of brick; I left it a city of marble." The population of the city at this time was probably about one million.
Although the government of Augustus was disturbed by some troubles upon the frontiers, still never before, perhaps, did the world enjoy so long a period of general rest from the preparation and turmoil of war. Three times during this auspicious reign the gates of the Temple of Janus at Kome, which were open in time of war and closed in time of peace, were shut. Only twice before during the entire history of the city had they been closed, so ​constantly had the Roman people been engaged in war. It was in the midst of this happy reign, when profound peace prevailed throughout the civilized world, that Christ was born in Bethlehem of Judea. The event was unheralded at Rome yet it was filled with profound significance, not only for the Roman empire, but for the world.
The latter years of the life of Augustus were clouded both by domestic bereavement and national disaster. His beloved nephew Marcellus, and his two grandsons Caius and Lucius, whom he purposed making his heirs, were all removed by death; and then, far away in the German forest, his general Varus, who had attempted to rule the freedom-loving Teutons as he had governed the abject Asiatics of the Eastern provinces, was surprised by the barbarians, led by their brave chief Hermann,—Arminius, as called by the Romans,—and his army destroyed almost to a man (a.d. 9). Twenty thousand of the legionaries lay dead and unburied in the tangled woods and morasses of Germany.
The victory of Arminius over the Roman legions was an event of the greatest significance in the history of European civilization. Germany was almost overrun by the Roman army. The Teutonic tribes were on the point of being completely subjugated and Romanized, as had been the Celts of Gaul before them. Had this occurred, the entire history of Europe would have been changed; for the Germanic element is the one that has given shape and color to the important events of the last fifteen hundred years. Those barbarians, too, were our ancestors. Had Rome succeeded in exterminating or enslaving them, Britain, as Creasy says, would never have received the name of England, and the great English nation would never have had an existence.
In the year A.D.14, Augustus died, having reached the seventy-sixth year of his age. It was believed that his soul ascended visibly amidst the flames of the funeral pyre. By decree of the Senate divine worship was accorded to him, and temples were erected in his honor.
One of the most important of the acts of Augustus, in its ​influence upon following events, was the formation of the Prætorian Guard, which was designed for a sort of body-guard to the emperor. In the succeeding reign this body of soldiers, about ten thousand in number, was given a permanent camp alongside the city walls. It soon became a formidable power in the state, and made and unmade emperors at will.
Reign of Tiberius (A.D. 14–37).—Tiberius succeeded to an unlimited sovereignty. The Senate conferred upon him all the titles that had been worn by Augustus. One of the first acts of Tiberius gave the last blow to the ancient republican institutions. He took away from the popular assembly the privilege of electing the consuls and prætors, and bestowed the same upon the Senate, which, however, must elect from candidates presented by the emperor. As the Senate was the creation of the emperor, who as censor made up the list of its members, he was now of course the source and fountain of all patronage.' During the first years of his reign, Tiberius used his practically unrestrained authority with moderation and justice, but soon yielding to the promptings of a naturally cruel, suspicious, and jealous nature, he entered upon a course of the most high-handed tyranny. He enforced oppressively an old law, known as the law of majestas, which made it a capital offence for any one to speak a careless word, or even to entertain an unfriendly thought, respecting the emperor. "It was dangerous to speak, and equally dangerous to keep silent," says Leighton, "for silence even might be construed into discontent." Rewards were offered to informers, and hence sprang up a class of persons called "delators," who acted as spies upon society. Often false charges were made, to gratify personal enmity; and many, especially of the wealthy class, were accused and put to death that their property might be confiscated.
Tiberius appointed, as his chief minister and as commander of the praetorians, one Sejanus, a man of the lowest and most corrupt life. This officer actually persuaded Tiberius to retire to the little island of Capreæ, in the Bay of Naples, and leave to him the management of affairs at Rome. The emperor built several ​villas in different parts of the beautiful islet, and, having gathered a band of congenial companions, passed in this pleasant retreat the later years of his reign. Both Tacitus the historian and Suetonius the biographer tell many stories of the scandalous profligacy of the emperor's life on the island; but these tales, it should be added, are discredited by some.
Meanwhile, Sejanus was ruling at Rome very much according to his own will. No man's life was safe. He even grew so bold as to plan the assassination of the emperor himself. His designs, however, became known to Tiberius; and the infamous and disloyal minister was arrested and put to death.
After the execution of his minister, Tiberius ruled more despotically than ever before. Multitudes sought refuge from his tyranny in suicide. Death at last relieved the world of the monster. His end was probably hastened by his attendants, who are believed to have smothered him in his bed, as he lay dying.
It was in the midst of the reign of Tiberius that, in a remote province of the Roman empire, the Saviour was crucified. Animated by an unparalleled missionary spirit, His followers traversed the length and breadth of the empire, preaching everywhere the "glad tidings." Men's loss of faith in the gods of the old mythologies, the softening and liberalizing influence of Greek culture, the unification of the whole civilized world under a single government, the widespread suffering and the inexpressible weariness of the oppressed and servile classes,—all these things had prepared the soil for the seed of the new doctrines. In less than three centuries the Pagan empire had become Christian not only in name, but also very largely in fact. This conversion of Rome is one of the most important events in all history. A new element is here introduced into civilization, an element which we shall find giving color and character to very much of the story of the eighteen centuries that we have yet to study.
Reign of Caligula (A.D. 37–41).—Caius Cæsar, better known as Caligula, was only twenty-five years of age when the death of Tiberius called him to the throne. His career was very similar to ​that of Tiberius. After a few months spent in arduous application to the affairs of the empire, during which time his many acts of kindness and piety won for him the affections of all classes, the mind of the young emperor became unsettled, and he began to indulge in all sorts of insanities. The cruel sports of the amphitheatre possessed for him a strange fascination. When animals failed, he ordered spectators to be seized indiscriminately, and thrown to the beasts. He entered the lists himself, and fought as a gladiator upon the arena. In a sanguinary mood, he wished that " the people of Rome had but one neck." As an insult to his nobles, he gave out that he proposed to make his favorite horse, Incitatus, consul. He declared himself divine, and removing the heads of Jupiter's statues, put on his own.
After four years the insane career of Caligula was brought to a close by some of the officers of the praetorian guard, whom he had wantonly insulted.
Reign of Claudius A.D. 41–54).—The reign of Claudius, Caligula's successor, was signalized by the conquest of Britain. Nearly a century had now passed since the invasion of the island by Julius Cæsar, who, as has been seen (see p. 292), simply made a reconnoissance of the island and then withdrew. Claudius conquered all the southern portion of the island, and founded many colonies, which in time became important centres of Roman trade and culture. The leader of the Britons was Caractacus. He was taken captive and carried to Rome. Gazing in astonishment upon the magnificence of the imperial city, he exclaimed, "How can a people possessed of such splendor at home envy Caractacus his humble cottage in Britain?"
Claudius distinguished his reign by the execution of many important works. At the mouth of the Tiber he constructed a magnificent harbor, called the Portus Romanus. The Claudian Aqueduct, which he completed, was a stupendous work, bringing water to the city from a distance of forty-five miles.
The delight of the people in gladiatorial shows had at this time become almost an insane frenzy. Claudius determined to give an ​entertainment that should render insignificant all similar efforts. Upon a large lake, whose sloping bank afforded seats for the vast multitudes of spectators, he exhibited a naval battle, in which two opposing fleets, bearing nineteen thousand gladiators, fought as though in real battle, till the water was filled with thousands of bodies, and covered with the fragments of the broken ships.
Throughout his life Claudius was ruled by intriguing favorites and unworthy wives. For his fourth wife Claudius married the "wicked Agrippina," who secured his death by means of a dish of poisoned mushrooms, in order to make place for the succession of her son Nero.
Reign of Nero (A.D. 54–68).—Nero was fortunate in having for his preceptor the great philosopher and moralist Seneca; but never was teacher more unfortunate in his pupil. For five years Nero ruled with moderation and equity. He then broke away from the guidance of his tutor Seneca, and entered upon a career filled with crimes of almost incredible enormity. The dagger and poison—the latter a means of murder the use of which at Rome had become a "fine art," and was in the hands of those who made it a regular profession—were employed almost unceasingly, to remove persons that had incurred his hatred, or who possessed wealth that he coveted.
It was in the tenth year of his reign that the so-called Great Fire laid more than half of Rome in ashes. It was rumored that Nero had ordered the conflagration to be lighted, and that from the roof of his palace he had enjoyed the spectacle, and amused himself by singing a poem which he had written, entitled the "Sack of Troy."
Nero did everything in his power to discredit the rumor. To turn attention from himself, he accused the Christians of having conspired to destroy the city, in order to help out their prophecies. The doctrine which was taught by some of the new sect respecting the second coming of Christ, and the destruction of the world by fire, lent color to the charge. The persecution that followed was one of the most cruel recorded in the history of the Church. ​Many victims were covered with pitch and burned at night, to serve as torches in the imperial gardens. Tradition preserves the names of the Apostles Peter and Paul as victims of this Neronian persecution.
As to Rome, the conflagration was a blessing in disguise. The city rose from its ashes as quickly as Athens from her ruins at the close of the Persian wars. The new buildings were made fireproof; and the narrow, crooked streets reappeared as broad and beautiful avenues. A considerable portion of the burnt region was appropriated by Nero for the buildings and grounds of an immense palace, called the "Golden House." It covered so much space that the people "maliciously hinted" that Nero had fired the old city, in order to make room for it.
The emperor secured money for his enormous expenditures by new extortions, murders, and confiscations. No one of wealth knew but that his turn might come next. A conspiracy was formed among the nobles to relieve the state of the monster. The plot was discovered, and again " the city was filled with funerals."
Lucan the poet, and Seneca, the old preceptor of Nero, both fell victims to the tyrant's rage.
Nero now made a tour through the East, and there plunged deeper and deeper into every shame, sensuality, and crime. The tyranny and the disgrace were no longer endurable. Almost at the same moment the legions in several of the provinces revolted. The Senate decreed that Nero was a public enemy, and condemned him to a disgraceful death by scourging, to avoid which he instructed a slave how to give him a fatal thrust. His last words were, "What a loss my death will be to art!"
Nero was the sixth and last of the Julian line. The family of the Great Cæsar was now extinct; but the name remained, and was adopted by all the succeeding emperors.
Galba, Otho, and Vitellius (A.D. 68–69).—These tnree names are usually grouped together, as their reigns were all short and uneventful. The succession, upon the death of Nero and the extinction in him of the Julian line, was in dispute, and the legions ​in different quarters supported the claims of their favorite leaders. One after another the three aspirants named were killed in bloody struggles for the imperial purple. The last, Vitellius, was hurled from the throne by the soldiers of Flavius Vespasian, the old and beloved commander of the legions in Palestine, which were at this time engaged in a war with the Jews.
Reign of Vespasian (A.D. 69–79).—The accession of Flavius Vespasian marks the beginning of a period, embracing three reigns, known as the Flavian Age (A.D. 69–96). Vespasian's reign was signalized both by important military achievements abroad and by stupendous public works undertaken at Rome.
In the opposite corner of the empire a dangerous revolt of the Gauls was suppressed, and in the island of Britain the Roman commander Agricola subdued or crowded back the native tribes until he had extended the frontiers of the empire into what is now ​Scotland. Then, as a protection against the incursions of the Caledonians, the ancestors of the Scottish Highlanders, he constructed a line of fortresses from the Frith of Forth to the Frith of Clyde.
Vespasian rebuilt the Capitoline temple, which had been burned during the struggle between his soldiers and the adherents of Vitellius; he constructed a new forum which bore his own name; and also began the erection of the celebrated Flavian amphitheatre, which was completed by his successor. After a most prosperous reign of ten years, Vespasian died A.D. 79, the first emperor after Augustus that did not meet with a violent death.
At the last moment he requested his attendants to raise him upon his feet that he might "die standing," as befitted a Roman emperor.
Reign of Titus (A.D. 79–81).—In a short reign of two years ​Titus won the title, the "Delight of Mankind." He was unwearied in acts of benevolence and in bestowal of favors. Having let a day slip by without some act of kindness performed, he is said to have exclaimed reproachfully, "I have lost a day."
Titus completed and dedicated the great Flavian amphitheatre begun by his father, Vespasian. This vast structure, which accommodated more than eighty thousand spectators, is better known as the Colosseum—a name given it either because of its gigantic proportions, or on account of a colossal statue of Nero which happened to stand near it.
The reign of Titus, though so short, was signalized by two great disasters. The first was a conflagration at Rome, which was almost as calamitous as the Great Fire in the reign of Nero. The second was the destruction, by an eruption of Vesuvius, of the Campanian cities of Pompeii and Herculaneum. The cities were buried ​beneath showers of cinders, ashes, and streams of volcanic mud. Pliny the elder, the great naturalist, venturing too near the mountain to investigate the phenomenon, lost his life.
Domitian—Last of the Twelve Cæsars (A.D. 81–96).—Domitian, the brother of Titus, was the last of the line of emperors known as "the Twelve Cæsars." The title, however, was assumed by, and is applied to, all succeeding emperors; the sole reason that the first twelve princes are grouped together is because the Roman biographer Suetonius completed the lives of that number only.
Domitian's reign was an exact contrast to that of his brother Titus. It was one succession of extravagances, tyrannies, confiscations, and murders. Under this emperor took place what is known in Church history as "the second persecution of the Christians." This class, as well as the Jews, were the special objects of Domitian's hatred, because they refused to worship the statues of himself which he had set up (see p. 322).
The last of the Twelve Cæsars perished in his own palace, and by the hands of members of his own household. The Senate ordered his infamous name to be erased from the public monuments, and to be blotted from the records of the Roman state.
The Five Good Emperors: Reign of Nerva (A.D. 96–98).—The five emperors—Nerva, Trajan, Hadrian, and the two Antonines—that succeeded Domitian were elected by the Senate, which during this period assumed something of its former weight and influence in the affairs of the empire. The wise and beneficent administration of the government by these rulers secured for them the enviable distinction of being called "the five good emperors." Nerva died after a short reign of sixteen months, ​and the sceptre passed into the stronger hands of the able commander Trajan, whom Nerva had previously made his associate in the government.
​the heart of the Assyrian monarchy. To Trajan belongs the distinction of extending the boundaries of the empire to the most distant points to which Roman ambition and prowess were ever able to push them.
But Trajan was something besides a soldier. He had a taste for literature: Juvenal, Plutarch, and the younger Pliny wrote under his patronage; and, moreover, as is true of almost all great conquerors, he had a perfect passion for building. Among the great works with which he embellished the capital was the Trajan Forum. Here he erected the celebrated marble shaft known as Trajan's column. It is one hundred and forty-seven
feet high and is wound from base to summit by a spiral band of sculptures, containing more than twenty-five thousand human figure's. The column is nearly as perfect to-day as when reared eighteen centuries ago. It was intended to commemorate the Dacian conquests of Trajan; and its pictured sides are the best, and almost the only, record we now possess of those wars.
Respecting the rapid spread of Christianity at this time, the character of the early professors of the new faith, and the light in which they were viewed by the rulers of the Roman world, we have very important evidence in a certain letter written by Pliny the Younger to the emperor in regard to the Christians of Pontus, ​in Asia Minor, of which remote province Pliny was governor. Pliny speaks of the new creed as a "contagious superstition, that had seized not cities only, but the lesser towns also, and the open country." Yet he could find no fault in the converts to the new doctrines. Notwithstanding this, however, because the Christians steadily refused to sacrifice to the Roman gods, he ordered many to be put to death for their "inflexible obstinacy."
Trajan died A.D. 117, after a reign of nineteen years, one of the most prosperous and fortunate that had yet befallen the lot of the Roman people.
Reign of Hadrian (A.D. 117–138).—Hadrian, a kinsman of Trajan, succeeded him in the imperial office. He possessed great ability, and displayed admirable moderation and prudence in the administration of the government. He gave up the territory conquered by Trajan in the East, and made the Euphrates once more the boundary of the empire in that quarter. He also broke down the bridge that Trajan had built over the Danube, and made that stream the real frontier line, notwithstanding the Roman garrisons were still maintained in Dacia. Hadrian saw plainly that Rome could not safely extend any more widely the frontiers of the empire. Indeed, so active and threatening were the enemies of the empire in the East, and so daring and numerous had now become its barbarian assailants of the North, that there was reason for the greatest anxiety lest they should break through even the old and strong lines of the Danube and the Euphrates, and pour their devastating hordes over the provinces.
More than fifteen years of his reign were spent by Hadrian in making tours of inspection through all the different provinces of the empire. He visited Britain, and secured the Roman possessions there against the Picts and Scots by erecting a continuous wall across the island. Next he journeyed through Gaul and Spain, and then visited in different tours all the remaining countries bordering upon the Mediterranean. He ascended the Nile,and, traveller-like, carved his name upon the vocal Memnon.The cities which he visited he decorated with temples, theatres and other monuments.
​In the year 131, the Jews in Palestine, who had in a measure recovered from the blow Titus had given their nation, broke out in desperate revolt, because of the planting of a Roman colony upon the almost desolate site of Jerusalem, and the placing of the statue of Jupiter in the Holy Temple. More than half a million of Jews perished in the useless struggle, and the survivors were driven into exile—the last dispersion of the race.
The latter years of his reign Hadrian passed at Rome. It was here that this princely builder erected his most splendid structures. Among these was the Mole, or Mausoleum, of Hadrian, an immense structure surmounted by a gilded dome, erected on the banks of the Tiber, and designed as a tomb for himself.
The Antonines (A.D. 138–180).—Aurelius Antoninus, surnamed Pius, the adopted son of Hadrian, and his successor, gave the Roman empire an administration singularly pure and parental. Of him it has been said that " he was the first, and, saving his colleague and successor Aurelius, the only one of the emperors who devoted himself to the task of government with a single view to the happiness of his people." Throughout his long reign of twenty-three years, the empire was in a state of profound peace. The attention of the historian is attracted by no striking events, which, as many have not failed to observe, illustrates admirably the oft-repeated maxim, "Happy is that people whose annals are brief."
Antoninus, early in his reign, united with himself in the government his adopted son Marcus Aurelius, and upon the death of the former (A.D. 161) the latter succeeded quietly to his place and work. His studious habits won for him the title of "Philosopher."
He belonged to the school of the Stoics, and was a most thoughtful writer. His Meditations breathe the tenderest sentiments of devotion and benevolence, and make the nearest approach to the spirit of Christianity of all the writings of Pagan antiquity. He established an Institution, or Home, for orphan girls; and, finding the poorer classes throughout Italy burdened by their taxes and greatly in arrears in paying them, he caused all the tax-claims to be heaped in the Forum and burned.
​The tastes and sympathies of Aurelius would have led him to choose a life passed in retirement and study at the capital; but hostile movements of the Parthians, and especially invasions of the barbarians along the Rhenish and Danubian frontiers, called him from his books, and forced him to spend most of the latter years of his reign in the camp. The Parthians, who had violated their treaty with Rome, were chastised by the lieutenants of the emperor, and Mesopotamia again fell under Roman authority.
This war drew after it a series of terrible calamities. The returning soldiers brought with them the Asiatic plague, which swept off vast numbers, especially in Italy, where entire cities and districts were depopulated. In the general distress and panic, the superstitious people were led to believe that it was the new sect of Christians that had called down upon the nation the anger of the gods. Aurelius permitted a fearful persecution to be instituted against them, during which the famous Christian fathers and bishops, Justin Martyr and Polycarp, suffered death.
It should be noted that the persecution of the Christians under the Pagan emperors, sprung from political rather than religious motives, and that this is why we find the names of the best emperors, as well as those of the worst, in the list of persecutors. It was believed that the welfare of the state was bound up with the careful performance of the rites of the national worship; and hence, while the Roman rulers were usually very tolerant, allowing all forms of worship among their subjects, still they required that men of every faith should at least recognize the Roman gods, and burn incense before their statues. This the Christians steadily refused to do. Their neglect of the service of the temple, it was believed, angered the gods, and endangered the safety of the state, bringing upon it drought, pestilence, and every disaster. This was the main reason of their persecution by the Pagan emperors.
But pestilence and persecution were both forgotten amidst the imperative calls for immediate help that now came from the North. The barbarians were pushing in the Roman outposts, and pouring impetuously over the frontiers. To the panic of the plague was ​added this new terror. Aurelius plaoed himself at the head of his legions, and hurried beyond the Alps. For many years, amidst the snows of winter and the heats of summer, he strove to beat back the assailants of the empire.
The efforts of the devoted Aurelius checked the inroads of the barbarians ; but he could not subdue them, so weakened was the empire by the ravages of the pestilence, and so exhausted was the treasury from the heavy and constant drains upon it. At last his weak body gave way beneath the hardships of his numerous campaigns, and he died in his camp at Vindobona (now Vienna), in the nineteenth year of his reign (a.d. 180).
The united voice of the Senate and people pronounced him a god, and divine worship was accorded to his statue. Never was Monarchy so justified of her children as in the lives and works of the Antonines. As Merivale, in dwelling upon their virtues, very justly remarks, "the blameless career of these illustrious princes has furnished the best excuse for Cæsarism in all after-ages."
