It is impossible to exaggerate the benefit conferred upon Europe by the Italians at this epoch. The culture of the classics had to be reappropriated before the movement of the modern mind could begin: before the nations could start upon a new career of progress, the chasm between the old and new world had to be bridged over. This task of reappropriation the Italians undertook alone, and achieved at the sacrifice of their literary independence and their political freedom. The history of Renaissance literature in Italy is the history of a national genius deviating from the course of self-development into the channels of scholarship and antiquarian research. The language created by Dante as a thing of power, polished by Petrarch as a thing of beauty, trained by Boccaccio as the instrument of melodious prose, was abandoned even by the Tuscans in the fifteenth century for revived Latin and newly-discovered Greek. Patent acquisition took the place of proud inventiveness; laborious imitation of classical authors suppressed originality of style. The force of mind which in the fourteenth century had produced a 'Divine Comedy' and a 'Decameron,' in the fifteenth was expended upon the interpretation of codices, the settlement of texts, the translation of Greek books into Latin, the study of antiquities, the composition of commentaries, encyclopædias, dictionaries, ephemerides. While we regret this change from creative to acquisitive literature, we must bear in mind that those scholars who ought to have been poets accomplished nothing less than the civilisation, or, to use their own phrase, the humanisation, of the modern world.[11] At the critical moment when the Eastern Empire was being shattered by the Turks, and when the other European nations were as yet unfit for culture, Italy saved the arts and sciences of Greece and Rome, and interpreted the spirit of the classics. Devoting herself to what appears the slavish work of compilation and collection, she transmitted an inestimable treasure to the human race; and though for a time the beautiful Italian tongue was superseded by a jargon of dead languages, yet the literature of the Renaissance yielded in the end the poetry of Ariosto, the political philosophy of Machiavelli, the histories of Guicciardini and Varchi. Meanwhile the whole of Europe had received the staple of its intellectual education.
