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.
