Tiberius performed with energy every duty that Augustus assigned to him. He rapidly, therefore, received military promotion. For thirty years he was a prominent and skillful general and acquired much experience in public affairs. He was strict in military discipline and a good administrative officer. He was sent across the Rhine nine times on important missions. Many believed him to possess those stern, Roman qualities that would fit him for the highest position. His temper, however, was somewhat surly and, like many of his contemporaries, he seems to have had little reluctance to shed blood.

He was admitted to an important and special share of the government two years before the death of Augustus. He was thirty-five years old when he came to the throne. His accession was quietly brought about by the careful management of his mother, Livia, by the support of the army, and by the acquiescence of the people.

The inheritor of a vast empire from his predecessor, Tiberius had at the outset much to do to keep its various parts in subordination. For some time he avoided foolish extravagance and insisted upon order and efficiency in the various departments. He defeated the plans of the enemies who had plotted against him, and showed much decision and firmness. He did not allow himself in the first years of his reign to come into conflict with the senators, and conciliated them in various ways. He was very obsequious, at the same time, to the wishes of his ambitious mother, Livia, who had always been watchful of his interests, and who was a great helper to his plans. The first nine years of his reign he was a conservative ruler. If he had died within that period he might have been rated by posterity as an industrious and patriotic monarch.

But even during that time he was unlike Augustus, in that he had none of those striking qualities that appeal to the sentiment and imagination of the people. He had no personal magnetism. He led in no great enterprises. He cared neither to provide nor to attend exciting gladiatorial shows. On the other hand, he was often gloomy and irritable, cynical in judgment, and fearful of the malice of his enemies. This tendency was afterward increased by disappointments in his domestic life. His marriage with Julia, the daughter of Augustus, owing to her bad character, proved to be unfortunate and unhappy. He turned against her, and fifteen years of later experience in life could not soften his attitude toward her.

The victories, triumphs, and death of his nephew, Germanicus, the son of his brother Drusus, occurred during his reign. Germanicus was a great soldier, a man of interesting character, and a sort of popular idol. While the people were giving themselves up to mourning over his death, Tiberius told them that both they and he should find the best consolation in attending to their regular duties. This seemed to them to be a very cold treatment of the occasion and confirmed their suspicions that the emperor had been jealous of Germanicus. It lessened his hold upon the affections of the people, although, to please them, he caused the arrest of Cnæus Piso, who was suspected of having poisoned Germanicus, and who committed suicide before he was sentenced.

At the same time Tiberius was completing the concentration of power in his own hands and began to employ delators, or spies, that he might detect and punish the beginnings of all plots against himself. He was suspicious of his subjects at Rome. “I have a wolf by the ears,” he said, referring to the great body of the people. This being his attitude of mind toward them, it is not strange that they lost for him their love and loyalty. His son, another Drusus, who had grown to be about thirty years old, was now associated as a consul of the empire with him.

The career of Tiberius rose to a certain height and then gradually declined. The turning-point was when he received into his intimate confidence an infamous adviser named Sejanus. He trusted this man more than he did the experienced officers of his realm. Sejanus was utterly selfish and corrupt, and willing to stop at no point in his domination of the emperor’s mind. Tiberius began to manifest a depressed and morose spirit. He frequently retired to the island of Capri, near Naples, for relief and recuperation. There, upon the high cliffs, amid beautiful scenery and the soft breezes of a salubrious climate, he made for himself extensive gardens and villas and gathered around him servile flatterers, who ministered to his vanity and catered to his caprices. He was fascinated by oriental superstitions and employed many sorcerors and magicians. Juvenal pictures the scene of the emperor sitting on a rock of Capri with his “Chaldeans” (that is, soothsayers) around him.

Tiberius continued in a large measure to direct through others the affairs of the empire. His son, Drusus II, proved to be a man of ability and discharged well the duties that were laid upon him. But Sejanus was made prefect and had the control of the city and of the Pretorian guard. It was Sejanus who took the bold step of bringing all the soldiers of that guard,—nine or ten thousand in number,—together into one camp, where they could be more at his own bidding. This camp was on the northeast border of Rome, where the square projection in the line of the walls still indicates its large proportions. Of course Drusus was in the way of Sejanus’ unprincipled ambitions; so the latter insidiously managed to gain influence over the wife of Drusus; and these two, Sejanus and this woman, together poisoned the promising heir to the throne. Tiberius was deceitfully told that the prince Drusus had died from sickness only. It was a severe blow to his fondest hopes. He manifested great grief before the Senate and mournfully declared that he must now transfer his hopes to the youthful children of Germanicus.
