much as by
the ostentation of his power, as by his power itself. The consul or the
tribune might have reigned in peace. The title of king had armed the
Romans against his life. Augustus was sensible that mankind is governed
by names; nor was he deceived in his expectation, that the senate and
people would submit to slavery, provided they were respectfully assured
that they still enjoyed their ancient freedom. A feeble senate and
enervated people cheerfully acquiesced in the pleasing illusion, as
long as it was supported by the virtue, or even by the prudence, of
the successors of Augustus. It was a motive of self-preservation, not a
principle of liberty, that animated the conspirators against Caligula,
Nero, and Domitian. They attacked the person of the tyrant, without
aiming their blow at the authority of the emperor.

[Footnote 27: Two centuries after the establishment of monarchy, the
emperor Marcus Antoninus recommends the character of Brutus as a perfect
model of Roman virtue. * Note: In a very ingenious essay, Gibbon has
ventured to call in question the preeminent virtue of Brutus. Misc
Works, iv. 95.--M.]

There appears, indeed, one memorable occasion, in which the senate,
after seventy years of patience, made an ineffectual attempt to
re-assume its long-forgotten rights. When the throne was vacant by the
murder of Caligula, the consuls convoked that assembly in the Capitol,
condemned the memory of the Caesars, gave the watchword liberty to the
few cohorts who faintly adhered to their standard, and during
eight-and-forty hours acted as the independent chiefs of a free
commonwealth. But while they deliberated, the praetorian guards had
resolved. The stupid Claudius, brother of Germanicus, was already in
their camp, invested with the Imperial purple, and prepared to support
his election by arms. The dream of liberty was at an end; and the senate
awoke to all the horrors of inevitable servitude. Deserted by the
people, and threatened by a military force, that feeble assembly was
compelled to ratify the choice of the praetorians, and to embrace the
benefit of an amnesty, which Claudius had the prudence to offer, and the
generosity to observe. [28]
