At first there was no way of acquiring the unknown tongue. But the second generation of Humanists sat at the feet of Byzantine masters. The first was Chrysoloras, who was sent to Italy on a political mission and settled in 1397 as a teacher of his own language at Florence. When he died, at the council of Constance, there were Italian scholars who could read Greek MSS. As teachers were scarce, adventurous men, such as Scarparia, Guarino, Aurispa, pursued their studies at Constantinople. Filelfo remained there for seven years, working in great libraries not yet profaned by the Turk. Before the middle of the fifteenth century Italy was peopled with migratory scholars, generally poor, and without fixed appointments, but able to rouse enthusiasm when they offered Plato for Henry of Ghent, and Thucydides for Vincent of Beauvais. By that time the superiority of the new learning, even in its very fragmentary condition, was irresistible. Just then three events occurred which determined the triumph of the Renaissance. The Emperor came over to the Council of Florence with a number of bishops and divines. In the discussions that followed, Greek scholars were in demand; and one Eastern prelate, Bessarion, remained in Italy, became a cardinal, and did much for the study of Plato and the termination of the long Aristotelian reign. His fine collection of manuscripts was at the service of scholars, and is still at their service, in St. Mark's library at Venice. The fall of Constantinople drove several fugitives to seek a refuge in Italy, and some brought their books with them, which were more scarce and more needful than men. For by that time Greek studies were well established, and suffered only from the extreme scarcity of manuscripts. The third important event was the election of Parentucelli, who became Pope Nicholas V. On that day the new learning took possession of the Holy See, and Rome began to be considered the capital of the Renaissance.
