罗马帝国衰亡史CHAPTER 1(Part I-2)
The principal conquests of the Romans were achieved under the republic; and the
emperors, for the most part, were satisfied with preserving those dominions which
had been acquired by the policy of the senate, the active emulations of the consuls, and the martial enthusiasm of the people. The seven first centuries were filled with a
rapid succession of triumphs; but it was reserved for Augustus to relinquish the
ambitious design of subduing the whole earth, and to introduce a spirit of moderation
into the public councils. Inclined to peace by his temper and situation, it was easy for
him to discover that Rome, in her present exalted situation, had much less to hope
than to fear from the chance of arms; and that, in the prosecution of remote wars, the
undertaking became every day more difficult, the event more doubtful, and the
possession more precarious, and less beneficial. The experience of Augustus added
weight to these salutary reflections, and effectually convinced him that, by the prudent
vigor of his counsels, it would be easy to secure every concession which the safety or
the dignity of Rome might require from the most formidable barbarians. Instead of
exposing his person and his legions to the arrows of the Parthians, he obtained, by an
honorable treaty, the restitution of the standards and prisoners which had been taken
in the defeat of Crassus.
