Upon the plan of those Memoirs, he afterwards composed a Latin poem in three books, in which he carried down the history to the end of his exile, but did not publish it for several years, from motives of delicacy. The three books were severally inscribed to the three Muses; but of this work there now remain only a few fragments, scattered in different parts of his other writings. He published, about the same time, a collection of the principal speeches which he had made in his consulship, under the title of his Consular Orations. They consisted originally of twelve; but four are entirely lost, and some of the rest are imperfect. He now published also, in Latin verse, a translation of the Prognostics of Aratus, of which work no more than two or three small fragments now remain. A few years after, he put the last hand to his Dialogues upon the Character and Idea of the perfect Orator. This admirable work remains entire; a monument both of the astonishing industry and transcendent abilities of its author. At his Cuman villa, he next began a Treatise on Politics, or on the best State of a City, and the Duties of a Citizen. He calls it a great and a laborious work, yet worthy of his pains, if he could succeed in it. This likewise was written in the form of a dialogue, in which the speakers were Scipio, Laelius, Philus, Manilius, and other great persons in the former times of the Republic. It was comprised in six books, and survived him for several ages, though it is now unfortunately lost. From the fragments which remain, it appears to have been a masterly production, in which all the important questions in politics and morality were discussed with elegance and accuracy.
