(iv.) _The Modern Age._--(a) Our fourth period is ushered in by the age of the Revival of Learning in Italy (c. 1350-1527). Petrarch (1304-1374) has been well described as "the first of modern men." In contrast with the Schoolmen of the middle ages, he has no partiality for Aristotle. He was interested in Greek, and, a full century before the fall of Constantinople, he was in possession of MSS. of Homer and Plato, though his knowledge of the language was limited to the barest rudiments. For that knowledge, scanty as it was, he was indebted to Leontius Pilatus, with whose aid Boccaccio (1313-1375) became "the first of modern men" to study Greek to some purpose during the three years that Leontius spent as his guest in Florence (1360-1363). It was also at Florence that Greek was taught in the next generation by Chrysoloras (in 1396-1400). Another generation passed, and the scholars of the East and West met at the council of Florence (1439). One of the envoys of the Greeks, Gemistus Pletho, then inspired Cosimo dei Medici with the thought of founding an academy for the study of Plato. The academy was founded, and, in the age of Lorenzo, Plato and Plotinus were translated into Latin by Marsilio Ficino (d. 1499). The _Apology_ and _Crito_, the _Phaedo, Phaedrus_ and _Gorgias_ of Plato, as well as speeches of Demosthenes and Aeschines, with the _Oeconomics, Ethics_ and _Politics_ of Aristotle, had already been translated by Leonardo Bruni (d. 1444); the _Rhetoric_ by Filelfo (1430), and Plato's _Republic_ by Decembrio (1439). A comprehensive scheme for translating the principal Greek prose authors into Latin was carried out at Rome by the founder of the manuscript collections of the Vatican, Nicholas V. (1447-1455), who had belonged to the literary circle of Cosimo at Florence. The translation of Aristotle was entrusted to three of the learned Greeks who had already arrived in Italy, Trapezuntius, Gaza and Bessarion, while other authors were undertaken by Italian scholars such as Guarino, Valla, Decembrio and Perotti. Among the scholars of Italian birth, probably the only one in this age who rivalled the Greeks as a public expositor of their own literature was Politian (1454-1494), who lectured on Homer and Aristotle in Florence, translated Herodian, and was specially interested in the Latin authors of the Silver Age and in the text of the _Pandects_ of Justinian. It will be observed that the study of Greek had been resumed in Florence half a century before the fall of Constantinople, and that the principal writers of Greek prose had been translated into Latin before that event.
