But though barren in poetry this interval was far from being barren in other intellectual results. This was the era of the great Roman orators, the successors of Laelius, Carbo, the Gracchi, etc., and the immediate predecessors and contemporaries of Cicero. It was through the care with which public speaking was cultivated that Latin prose was formed into that clear, exact, dignified, and commanding instrument, which served through so many centuries as the universal organ of history, law, philosophy, learning, and religion,--of public discussion and private correspondence. While Latin poetry is, both in spirit and manner, quite as much Italian as Roman, Latin prose bears the stamp of the political genius of Rome. It was the deliberate expression of the mind of men practised in affairs, exercised in the deliberations of the Senate, the harangues of the public assemblies, the pleadings of the courts,--of men accustomed to determine and explain questions of law and to draw up edicts binding on all subjects of the State,--trained, moreover, to a sense of literary form by the study of Greek rhetoric, and naturally guided to clearness and dignity of expression by the orderly understanding, the strong hold on reality, and the authoritative bearing which were their birthright as Romans. The effort which obtained its crowning success in the prose style of Cicero left its mark on other forms of literature. History continued to be written by members of the great governing families to serve both as a record of events and a weapon of party warfare. The large and varied correspondence of Cicero shows how general the accomplishment of style had become among educated men. And if this result was, in the main, due to the fervour of mind and temper elicited by the contests of public life, the systematic teaching of grammarians and rhetoricians acted as a corrective of the natural exuberance or carelessness of the rhetorical faculty.
