Hitherto, with the exception only of Boccaccio's Greek studies, I have had to trace the rise of Latin letters and to call particular attention to the cult of Cicero in Italy. It is now necessary to mention the advent of a man who played a part in the revival of learning only second to that of Petrarch. Manuel Chrysoloras, a Byzantine of noble birth, came to Italy during the Pontificate of Boniface IX., charged by the Emperor Palæologus with the mission of attempting to arm the states of Christendom against the Turk. Like all the Greeks who visited Western Europe, Chrysoloras first alighted in Venice; but the Republic of the Lagoons neither understood the secret nor felt the need of retaining these birds of passage. After a few months they almost invariably passed on to Florence--the real centre of the intellectual life of Italy. As soon as it was known that Chrysoloras, who enjoyed the fame of being the most accomplished and eloquent Hellenist of his age, had arrived with his companion, Demetrios Kydonios, in Venice, two noble Florentines, Roberto de' Rossi and Giacomo d'Angelo da Scarparia, set forth to visit him. The residence of the Greek ambassadors in Italy on this occasion was but brief; they found that, politically, they could effect nothing. But Giacomo da Scarparia journeyed in their society to Byzantium; while Roberto de' Rossi returned to Florence, full of the impression which the erudite philosophers had left upon him. The report he made to his fellow-citizens awoke a passionate desire in Palla degli Strozzi and Niccolo de' Niccoli to bring Chrysoloras in person to Florence. Their urgent appeals to the Signory resulted in an invitation whereby Chrysoloras in 1396 was induced to fill the Greek chair in the university. A yearly stipend of 150 golden florins, raised afterwards to 250, was voted for his maintenance. This engagement secured the future of Greek erudition in Europe. The merit of having brought the affair to a successful issue belongs principally to Palla degli Strozzi, of whom Vespasiano wrote: 'There being in Florence exceeding good knowledge of Latin letters, but of Greek none, he resolved that this defect should be remedied, and therefore did all he could to make Manuel Grisolora visit Italy, using all his influence thereto and paying a large portion of the expense incurred.'[70] We must not, however, omit the share which Coluccio Salutato,[71] by his influence with the Signory, and Niccolo de' Niccoli, by the interest he exerted with the Uffiziali dello Studio, may also claim. Among the audience of this the first true teacher of Greek at Florence were numbered Palla degli Strozzi, Roberto de' Rossi, Poggio Bracciolini, Lionardo Bruni, Francesco Barbaro, Giannozzo Manetti, Carlo Marsuppini, and Ambrogio Traversari--some of them young men of eighteen, others old and grey-haired, nearly all of them the scholars in Latinity of Giovanni da Ravenna. Nor was Florence the only town to receive the learning of Chrysoloras.
