successor. Tiberius was a Claudian, and that a knight without ancestry
should be placed at the head of the Roman aristocracy was to him
unthinkable; after the exile of Nero he had cast his eyes upon Caius,
another son of Germanicus, as his possible successor. Nor had he
hidden his intention: he had even clearly expressed it in different
speeches to the senate. Therefore Sejanus must finally have come to
the conclusion that if he continued to defend Tiberius and his
interests, he could no longer hope for anything from him, and might
even compromise the influence and the popularity which he had already
acquired. Tiberius was hated and detested, there was a numerous party
opposed to him in the senate, and he was extremely unpopular among the
masses. Many admired Sejanus through spiteful hatred of Tiberius, for
it amounted to saying that they preferred to be governed by an obscure
knight rather than by an old and detested Claudian who had shut himself
up in Capri.

And thus Sejanus seems to have deluded himself into believing that if
he succeeded in doing away with the emperor, he could easily take his
position by setting aside the young son of Germanicus and profiting by
the popularity which the fall of Tiberius would bring him. Little by
little he came to an understanding with the enemies of Tiberius and
prepared a conspiracy for the final overthrow of the odious government
of the son of Livia. Many senators had agreed to this, and certainly
few conspiracies were ever organized under more favorable auspices.
Tiberius was old, disgusted with everything and everybody, and alone in
Capri; he had virtually not a single friend in Rome; what happened in
the world he knew only through what Sejanus told him. He was therefore
entirely in the hands of the man who was preparing to sacrifice him to
the tenacious hatred of the people and the senatorial aristocracy.
Young, energetic, and the favorite of fortune, Sejanus had with him a
