There are still some fragments remaining of the letters which Cæsar addressed to the Senate and his friends, and also of his orations, which were considered as inferior only to those of Cicero. Of his rhetorical talents, something may be hereafter said. It appears that his qualities as an orator and historian, were very different, since vehemence and the power of exciting emotion, (concitatio,) are mentioned as the characteristics of his harangues. Some of them were delivered in behalf of clients, and on real business, in the Forum; but the two orations entitled _Anticatones_ were merely written in the form and manner of accusations before a judicial tribunal. These rhetorical declamations, which were composed about the time of the battle of Munda, were intended as an answer to the laudatory work of Cicero, called _Laus Catonis_. The author particularly considered in them the last act of Cato at Utica, and has raked up all the vices and defects of his character, whether real or imputed, public or private,—his ambition, affectation of singularity, churlishness, and avarice; but as the _Anticatones_ were seasoned with lavish commendations of Cicero, whose panegyric on Cato they were intended to confute, the orator felt much flattered with the dictatorial incense, and greatly admired the performances in which it was offered,—“Collegit vitia Catonis, sed cum maximis laudibus meis(205).” These two rival works were much celebrated at Rome; and both of them had their several admirers, as different parties and interests disposed men to favour the subject, or the author of each. It seems also certain, that they were the principal cause of establishing and promoting that veneration which posterity has since paid to the memory of Cato; for his name being thrown into controversy in that critical period of the fate of Rome, by the patron of liberty on one side, and its oppressor on the other, it became a kind of political test to all succeeding ages, and a perpetual argument of dispute between the friends of freedom, and the flatterers of power(206). The controversy was taken up by Brutus, the nephew, and Fabius Gallus, an admirer of Cato: it was renewed by Augustus, who naturally espoused the royal side of the question, and by Thraseas Pætus, who ventured on this dangerous topic during the darkest days of imperial despotism. Cæsar’s situation as Pontifex Maximus probably led him to write the _Auguralia_ and _Libri Auspiciorum_, which, as their names import, were books explaining the different auguries and presages derived from the flight of birds. To the same circumstance we may attribute his work on the motions of the stars, _De Motu Siderum_, which explains what he had learned in Egypt on that subject from Sosigenes, a peripatetic philosopher of Alexandria, and in which, if we may credit the elder Pliny, he prognosticated his own death on the ides of March(207).
