In 1438, Cosimo instituted the famous Platonic Academy of Florence, the special purpose of which was the interpretation of Greek philosophy. The gathering in Florence, in 1438, of the Greeks who came to the great Council, had a large influence in stimulating the interest of Florentines in Greek culture. Symonds (possibly somewhat biassed in favour of his beloved Florentines of the Renaissance) contends that the Byzantine ecclesiastics who came to the Council, and the long series of Greek travellers or refugees who found their way from Constantinople to Italy during the years that followed, included comparatively few real scholars whose classical learning could be trusted. These men supplied, says Symonds, “the beggarly elements of grammar, caligraphy, and bibliographical knowledge,” but it was Ficino and Aldus, Strozzi and Cosimo de’ Medici who opened the literature of Athens to the comprehension of the modern world. The elevation to the papacy, in 1447, of Tommaso Parentucelli, who took the name of Nicholas V., had the effect of carrying to Rome some of the Florentine interest in literature and learning. Tommaso, who was a native of Pisa, had won repute in Bologna for his wide and thorough scholarship. He became, later, a protégé of Cosimo de’ Medici, who employed him as a librarian of the Marcian Library. To Nicholas V. was due the foundation of the Vatican Library, for which he secured a collection of some five thousand works. Symonds says that during his pontificate, “Rome became a vast workshop of erudition, a factory of translations from Greek and Latin.” The compensation paid to these translators from the funds provided by the Pope, was in many cases very liberal. In fact, as compared with the returns secured at this period for original work, the rewards paid to these translators of the Vatican seem decidedly disproportionate, especially when we remember that a large portion of their work was of poor quality, deficient both in exact scholarship and in literary form. To Lorenzo Valla was paid for his translation of Thucydides, 500 scudi, to Guarino for a version of Strabo, 1500 scudi, to Perotti for Polybius, 500 ducats. Manetti had a pension of 600 scudi a month to enable him to pursue his sacred studies. Poggio’s version of the _Cyropædia_ of Xenophon and Filelfo’s rendering of the poems of Homer, were, from a literary point of view, more important productions. Some of the work in his series of translations was confided by the Pope to the resident Greek scholars. Trapezuntios undertook the _Metaphysics_ of Aristotle and the _Republic_ of Plato, and Tifernas the _Ethics_ of Aristotle. Translations were also prepared of Theophrastus and of Ptolemy.
