Tiberius was the storm-center of these struggles, and contrary to what legend has reported, he attempted as far as he was able to prevent the two parties from going to extremes. But what pain, repugnance, and fatigue it must have cost him to make the effort necessary for maintaining a last ray of reason and justice among so many evil passions, animosities, ambitions, and rivalries! It must have cost him dearly, for he had grown up in the time when the dream of a great restoration of the aristocracy was luring the upper classes of Rome with its fairest and most luminous smile. As a young man he had known and loved Vergil, Horace, and Livy, the two poets and the historian of this great dream; like all the elect spirits of those now distant years, he had seen behind this vision a great senate, a glorious and terrible army, an austere and revered republic like that which Livy had pictured with glowing colors in his immortal pages.
Instead of all this, he was now forced to take his place at the head of this decadent and wretched nobility, which seemed to be interested only in rending itself asunder with calumnies, denunciations, suits, and scandalous condemnations, and which repaid him for all that he had done and was still doing for its safety and the prosperity of the empire by directing against his name the most atrocious calumnies, the fiercest railleries, and every sort of ridiculous and infamous legend. He had dreamed of victories over the enemies of Rome, and he had to resign himself to struggling day and night against the hysterical extravagance of Agrippina: he had to be content, even without the sure hope of success, if he could convince the majority that he was not a poisoner. Authority without glory or respect, power divorced from the means sufficient for its exercise—such was the situation in which the successor of Augustus, the second emperor, after twelve years of a difficult and trying reign, found himself. He no longer felt himself safe at Rome, where he feared rightly or wrongly that his life was being continually threatened, and it is not astonishing that, old, wearied, and disgusted, between the years 26 and 27 he should have retired definitely to Capri, seeking to hide his misanthropy, his weariness, and his disgust with men and things in the wonderful little isle which a delightful caprice of nature had set down in the lap of the divine Bay of Naples.
But instead of the peace he sought at Capri, Tiberius found the infamy of history. How dark and terrible are the memories of him associated with the charming isle, which, violet-tinted, on beautiful sunny days emerges from an azure sea against an azure sky! That fragment of paradise fallen upon the shore of one of the most beautiful seas in the world is said to have been for about ten years a hell of fierce cruelties and abominable vices. Tiberius passed sentence upon himself, in the opinion of posterity, when he secluded himself in Capri. Ought we, without a further word, to transcribe this sentence? There are, to be sure, no decisive arguments to prove false the accounts about the horrors of Capri which the ancients, and especially Suetonius, have transmitted to us; there are some, however, which make us mistrust and withhold our judgment. Above all, we have the right to ask ourselves how, from whom, and by access to what sources did Suetonius and the other ancients learn so many extraordinary details. It must be remembered that all the great figures in the history of Rome who had many enemies, like Sylla, Caesar, Antony, and Augustus himself, were accused of having scandalous habits. Precisely because the puritan tradition was strong at Rome, such an accusation did much harm, and for this reason, whether true or false, enemies were glad to repeat it whenever they wished to discredit a character. Lastly, all the ancient writers, even the most hostile, tell us that up to a ripe age Tiberius preserved his exemplary habits. Is it likely, then, that suddenly, when already old, he should have soiled himself with all the vices? At all events, if there is any truth contained in these accounts, we can at most conclude that as an old man Tiberius became subject to some mental infirmity and that the man who took refuge at Capri was no longer entirely sane.
Certain it is, in any case, that after his retirement to Capri, Tiberius seriously neglected public affairs, and that Sejanus was finally looked upon at Rome as the de facto emperor. The bulletins and reports which were sent from the empire and from Rome to the emperor passed through his hands, as well as the decisions which Tiberius sent back to the state. At Rome, in all affairs of serious or slight importance, the senators turned to Sejanus, and about him, whom all fell into the habit of considering as the true emperor, a court and party were formed. In fear of his great power, the senators and the old aristocracy suppressed the envy which the dizzy rise of this obscure knight had aroused. Rome suffered without protest that a man of obscure birth should rule the empire in the place of a descendant of the great Claudian family, and the senators of the most illustrious houses grew accustomed to paying him court. Worse still, virtually all of them aided him, either by openly favoring him or by allowing him a free hand, to complete the decisive destruction of the party and the family of Germanicus,—of that same Germanicus of whom all had been fond and whose memory the people still venerated.

After the retirement of Tiberius to Capri, all felt that Agrippina and her sons were inevitably doomed sooner or later to succumb in the duel with the powerful, ambitious, and implacable prefect of the pretorians who represented Tiberius at Rome. Only a few generous idealists remained faithful to the conquered, who were now near their destruction; such supporters as might possibly ease the misery of ruin, but not ward it off or avoid it. Among these last faithful and heroic friends was a certain Titius Sabinus, and the implacable Sejanus destroyed him with a suit of which Tacitus has given us an account, a horrible story of one of the most abominable judicial machinations which human perfidy can imagine. Dissensions arose to aggravate the already serious danger in which Agrippina and her friends had been placed. Nero, the first-born son, and Drusus, the second, became hostile at the very moment when they should have united against the ruthless adversary who wished to exterminate them all. A last rock of refuge remained to protect the family of Germanicus. It was Livia, the revered old lady who had been present at the birth of the fortunes of Augustus and the new imperial authority, and who had held in her arms that infant world which had been born in the midst of the convulsions of the civil wars, and a little later had watched it try its first steps on the pathway of history. Livia did not much love Agrippina, whose hatred and intrigues against Tiberius she had always blamed; but she was too wise and too solicitous of the prestige of the family to allow Sejanus entirely to destroy the house of Germanicus. As long as she lived, Agrippina and Nero could dwell safely in Rome. But Livia was feeble, and in the beginning of 29, at the age of eighty-six, she died. The catastrophe which had been carefully prepared by Sejanus was now consummated; a few months after the death of Livia, Agrippina and Nero were subjected to a suit, and, under an accusation of having conspired against Tiberius, were condemned to exile by the senate. Shortly after his condemnation, Nero committed suicide.
The account which Tacitus gives us of this trial is obscure, involved, and fragmentary, for the story is broken off at its most important point by an unfortunate lacuna in the manuscript. The other historians add but little light with their brief phrases and passing allusions. We do not therefore entirely understand either the contents of the charges, the reason for the condemnation, the stand taken by the accused, or the conduct of Tiberius with regard to the accusation. It seems hardly probable that Agrippina and Nero could have been truly guilty of a real conspiracy against Tiberius. Isolated as they had been by Sejanus after the retirement of Tiberius to Capri, they would scarcely have been able to set a conspiracy on foot, even if they had so desired. They were paying the penalty for the long war of calumnies and slanders which they had waged upon Tiberius, for the aversion and the scorn which they had always shown for him. In this course of conduct many senators had encouraged them as long as Tiberius alone had not dared to have recourse to violent and cruel measures in order to make himself respected by his family. But such acts of disrespect became serious crimes for the unfortunate woman and her hapless son, even in the eyes of the senators who had encouraged them to commit them, now that Sejanus had reinvigorated the imperial authority with his energy, and now that all felt that behind Tiberius and in his name and place there was acting a man of decision who knew how to punish his enemies and to reward his friends.
The trial and condemnation of Agrippina and Nero were certainly the machinations of Sejanus, who carried along with him not only the senate and the friends of the imperial family, but perhaps even Tiberius himself. They prove how much Sejanus had been able to strengthen imperial authority, which had been hesitating and feeble in the last decade. Sejanus had dared to do what Tiberius had never succeeded in doing; he had destroyed that center of opposition which gathered about Agrippina in the house of Germanicus. It is therefore scarcely necessary to say that the ruin of Agrippina still further increased the power of Sejanus. All bowed trembling before the man who had dared humiliate the very family of the Julio-Claudii. Honors were showered upon his head; he was made senator and pontifex; he received the proconsular power; there was talk of a marriage between him and the widow of Nero; and it was finally proposed that he be named consul for five years. Indeed, in 31, through the will of Tiberius, he actually became the colleague of the emperor himself in the consulate. He needed only the tribunician power to make him the official collaborator of the emperor and his designated successor. Every one at Rome, furthermore, considered him the future prince.
