The Conspiracy of Catiline (his first published work) contains the history of the memorable year 63. Sallust adopts the usually accepted view of Catiline, and describes him as the deliberate foe of law, order and morality, and does not give a comprehensive explanation of his views and intentions. Catiline had supported the party of Sulla, to which Sallust was opposed. Sallust's Jugurthine War is a valuable and interesting monograph. We may assume that Sallust collected materials and put together notes for it during his governorship of Numidia. Here, too, he dwells upon the feebleness of the senate and aristocracy.
