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 prætorian guard, whom he had wantonly insulted.
REIGN OF CLAUDIUS (A.D. 4l-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.
