Atticus’ annals seem to have been only tables; but a very valuable work. Quotations, however, from them we read nowhere; so that we may infer, that in all likelihood there were many such books of which we know nothing.[18] In that introduction of wondrous beauty to his books _De Legibus_, Cicero speaks of having been asked to write the Roman history, as a duty the fulfilment of which his country expected from him. He expresses himself on the subject in such a manner, as clearly to show that he would certainly have liked the work, but that indeed he had never thought of it in right earnest. Had he done so, we may, without losing sight of the reverence due to so great a man, assert, that he would have taken upon himself a task for which he was quite unsuited. From the books _De Republica_, we see with how incredibly little previous reading he set about the description of the constitution. He seems not to have made any use of Gracchanus; but to have derived his knowledge chiefly from Polybius, and perhaps from Atticus. His proper calling was that of a statesman, and not of a scholar. Many authors are yet to be mentioned; Antipater, Fannius, Polybius, Posidonius, Rutilius, Lucullus, Scaurus, and others, part of whom have written in Greek.[19] Sallust found the Roman history in a neglected state; he expresses himself to that effect in his Catiline, and says, that it would be a task for a man, who had the capacity for writing it. And he would have had the capacity; but the Romans had no more a Roman history than we have a German one. Sallust was a busy practical man, who would not, and could not devote his life to the immense preparatory studies, which were required for it. He therefore wisely chose to write detached parts of Roman history, which were perhaps intended at a future period to form a whole. Thus he wrote the history of Jugurtha, in which it was his main object to point out to his readers the reaction in favour of the crushed popular party against the aristocrats, who had so shamefully abused their victory. He therefore is careful to show how Rome then in every respect was full of rottenness within. His histories began from the time after Sylla’s death, and described the revolution against Sylla’s ill-judged counter-revolution, and the struggle of Sertorius. Catiline’s conspiracy is to prove, what consummate ruffians, after all, those partisans of Sylla were, who called themselves the _optimates_, the _boni_. Between the time of Jugurtha and the consulate of Lepidus, the historical work of Sisenna formed the connecting link. With this Sallust no doubt was satisfied; otherwise he would have treated also of that period.
