Any survey of the Court of Nicholas V. would be incomplete without some notice of the Cardinal Bessarion. Early in life he rose to high station in the Greek Church, and attended the Council of Florence as Archbishop of Nicea. Eugenius IV., by making him a cardinal in 1439, converted him to the Latin faith; and, as it so happened, he missed the Papacy almost by an accident thirty-two years later.[223] His palace at Rome became the meeting-place of scholars of all nations,[224] where refugee Greeks in particular were sure of finding hearty welcome. In obedience to the reigning passion for book-collecting, he got together a considerable library of Greek and Latin authors, the number of which Vespasiano estimated at 600 volumes, while Platina reckoned their total cost at 30,000 scudi. In 1468 he offered this collection to the Church of S. Mark at Venice. The Republic accepted his gift, but showed no alacrity to build the library. It was not until the next century that Bessarion's books were finally housed according to their dignity.[225] The Cardinal's own studies lay in the direction of theological philosophy. We have already seen that in his youth he was a pupil of Gemistos, and he now appears as the defender of Plato. Georgios Trapezuntios had published a treatise in the year 1458, in which, on the pretence of upholding Aristotle, he vilified Plato's moral character, accused him of having ruined Greece, and maintained that Mahomet was a far better legislator. Bessarion replied by the oration 'In Calumniatorem Platonis,' vindicating the morality of the philosopher and supporting him against Aristotle. This book was printed by Sweynheim and Pannartz in the infancy of the Roman press. Theodoros Gaza,[226] who, on his settlement in Rome in 1450, had been received into Bessarion's household, entered the lists with a critique of Gemistos; to which Bessarion replied: and so the warfare begun by Gennadios at Byzantium was continued by the Greek exiles at Rome. The titles of the works issued in this contest, among which we find 'De Naturâ et Arte,' 'Utrum Natura Consilio Agat,' 'Comparationes Philosophorum Aristotelis et Platonis,' sufficiently indicate the extent of ground traversed. The chief result was the rousing of Italian scholars to weightier points of issue in philosophy than had at first been raised by mystical Neoplatonists and pedantic Peripatetics.
