Ea tempestate mihi imperium populi Romani multo maxume miserabile visum est. Cui cum ad occasum ab ortu solis omnia domita armis parerent, domi otium atque divitiae, quae prima mortales putant, adfluerent, fuere tamen cives, qui seque remque publicam obstinatis animis perditum irent. namque duobus senati decretis ex tanta multitudine neque praemio inductus coniurationem patefecerat neque ex castris Catilinae quisquam omnium discesserat: tanta vis morbi atque uti tabes plerosque civium animos invaserat.
(Sallust, Bell. Cat. 36.4-5)
At that time, it seems to me, the empire of the Roman people was in an especially deplorable state. Everything from the rising sun to the setting sun was dominated by and obedient to Roman arms; and at home there was abundant peace and wealth, things that humans consider most important. But nevertheless there were citizens who with unwavering hearts were intent on destroying themselves and their state. Indeed, in spite of two decrees that were passed by the Senate, no one from that great multitude of men was induced to expose the conspiracy and no one at all left the camp of Catiline. Such was the force of the disease that like a plague had invaded the minds of many citizens. (tr. William W. Batstone)
