Sallust, Conspiracy of Catiline
John Selby Watson, Rev. John Selby Watson, M.A., Ed.

Some time afterward, Piso was sent as quæstor, with Prætorian authority, into Hither Spain; Crassus promoting the appointment, because he knew him to be a bitter enemy to Cneius Pompey. Nor were the senate, indeed, unwilling¹ to grant him the province; for they wished so infamous a character to be removed from the seat of government; and many worthy men, at the same time, thought that there was some security in him against the power of Pompey, which was then becoming formidable. But this Piso, on his march toward his province, was murdered by some Spanish cavalry whom he had in his army. These barbarians, as some say, had been unable to endure his unjust, haughty, and cruel orders; but others assert that this body of cavalry, being old and trusty adherents of Pompey, attacked Piso at his instigation; since the Spaniards, they observed, had never before committed such an outrage, but had patiently submitted to many severe commands. This question we shall leave undecided. Of the first conspiracy enough has been said.
