We have now to notice its intrusion into the sphere of politics. Petrarch died in 1374, Boccaccio in 1375. The latter date is also that of Coluccio de' Salutati's entrance upon the duties of Florentine Chancellor. Salutato, the friend of Boccaccio and the disciple of Marsigli, the professed worshipper of Petrarch and the translator of Dante into Latin verse, was destined to exercise an important influence in his own department as a stylist. Before he was called to act as secretary to the Signory of Florence in his forty-sixth year, he had already acquired the learning and imbibed the spirit of his age. He was known as a diligent collector of manuscripts and promoter of Greek studies, as a writer on mythology and morals, as an orator and miscellaneous author.[64] His talents had now to be concentrated on the weightier business of the Florentine Republic; but his study of antiquity caused him to conceive his duties and the political relations of the State he served, in a new light. During the wars carried on with Gregory XI. and the Visconti, his pen was never idle. For the first time he introduced into public documents the gravity of style and melody of phrase he had learned in the school of classic rhetoricians. The effect produced by this literary statesman, as elegant in authorship as he was subtle in the conduct of affairs, can only be estimated at its proper value when we remember that the Italians were now ripe to receive the influence of rhetoric, and only too ready to attribute weight to verbal ingenuity. Gian Galeazzo Visconti is said to have declared that Salutato had done him more harm by his style than a troop of paid mercenaries.[65] The epistles, despatches, protocols, and manifestoes composed by their Chancellor for the Florentine priors, were distributed throughout Italy. Read and copied by the secretaries of other states, they formed the models of a new State eloquence.[66] Elegant Latinity became a necessary condition of public documents, and Ciceronian phrases were henceforth reckoned among the indispensable engines of a diplomatic armoury. Offices of trust in the Papal Curia, the courts of the Despots, and the chanceries of the republics were thus thrown open to professional humanists. In the next age we shall find that neither princes, popes, nor priors could do without the services of trained stylists.
