_De Provinciis Consularibus_. The government of Gaul was continued to Cæsar, in consequence of this oration, so that it may be considered as one of the immediate causes of the ruin of the Roman Republic, which it was incontestibly the great wish of Cicero to protect and maintain inviolate. But Cicero had evidently been duped by Cæsar, as he formerly had nearly been by Catiline, and as he subsequently was by Octavius, Pollio, and every one who found it his interest to cajole him, by proclaiming his praises, and professing ardent zeal for the safety of the state. So little had he penetrated the real views of Cæsar, that we find him asking the Senate, in his oration, what possible motive or inducement Cæsar could have to remain in the province of Gaul, except the public good. “For would the amenity of the regions, the beauty of the cities, or civilization of the inhabitants, detain him there—or can a return to one’s native country be so distasteful?” _Pro Cornelio Balbo_.—Balbus was a native of Cadiz, who having been of considerable service to Pompey, during his war in Spain, against Sertorius, had, in return, received the freedom of Rome from that commander, in virtue of a special law, by which he had obtained the power of granting this benefit to whom he chose. The validity of Pompey’s act, however, was now questioned, on the ground that Cadiz was not within the terms of that relation and alliance to Rome, which could, under any circumstances, entitle its citizens to such a privilege. The question, therefore, was, whether the inhabitants of a federate state, which had not adopted the institutions and civil jurisprudence of Rome, could receive the rights of citizenship. This point was of great importance to the municipal towns of the Republic, and the oration throws considerable light on the relations which existed between the provinces and the capital. _In Pisonem_.—Piso having been recalled from his government of Macedon, in consequence of Cicero’s oration, _De Provinciis Consularibus_, he complained, in one of his first appearances in the Senate, of the treatment he had received, and attacked the orator, particularly on the score of his poetry, ridiculing the well known line, “Cedant arma togæ—concedat laurea linguæ.”
