The subjects chosen by Sallust form two of the most important and prominent topics in the history of Rome. The periods, indeed, which he describes, were painful, but they were interesting. Full of conspiracies, usurpations, and civil wars, they chiefly exhibit the mutual rage and iniquity of embittered factions, furious struggles between the patricians and plebeians, open corruption in the senate, venality in the courts of justice, and rapine in the provinces. This state of things, so forcibly painted by Sallust, produced the Conspiracy, and even in some degree formed the character of Catiline: But it was the oppressive debts of individuals, the temper of Sylla’s soldiers, and the absence of Pompey with his army, which gave a possibility, and even prospect of success to a plot which affected the vital existence of the commonwealth, and which, although arrested in its commencement, was one of those violent shocks which hasten the fall of a state. The History of the Jugurthine War, if not so important or menacing to the vital interests and immediate safety of Rome, exhibits a more extensive field of action, and a greater theatre of war. No prince, except Mithridates, gave so much employment to the arms of the Romans. In the course of no war in which they had ever been engaged, not even the second Carthaginian, were the people more desponding, and in none were they more elated with ultimate success. Nothing can be more interesting than the account of the vicissitudes of this contest. The endless resources, and hair-breadth escapes of Jugurtha—his levity, his fickle faithless disposition, contrasted with the perseverance and prudence of the Roman commander, Metellus, are all described in a manner the most vivid and picturesque.
