The Renaissance movement first received definite direction from the rediscovery and study of Greek literature, which clearly revealed the unbounded possibilities of life to men who had been groping dissatisfied within the now narrow limits of medieval thought. Before Chaucer was dead the study of Greek, almost forgotten in Western Europe during the Middle Ages, had been renewed in Italy, and it received a still further impulse when at the taking of Constantinople by the Turks in 1453 Greek scholars and manuscripts were scattered to the West. It is hard for us to-day to realize the meaning for the men of the fifteenth century of this revived knowledge of the life and thought of the Greek race. The medieval Church, at first merely from the brutal necessities of a period of anarchy, had for the most part frowned on the joy and beauty of life, permitting pleasure, indeed, to the laity, but as a thing half dangerous, and declaring that there was perfect safety only within the walls of the nominally ascetic Church itself. The intellectual life, also, nearly restricted to priests and monks, had been formalized and conventionalized, until in spite of the keenness of its methods and the brilliancy of many of its scholars, it had become largely barren and unprofitable. The whole sphere of knowledge had been subjected to the mere authority of the Bible and of a few great minds of the past, such as Aristotle. All questions were argued and decided on the basis of their assertions, which had often become wholly inadequate and were often warped into grotesquely impossible interpretations and applications. Scientific investigation was almost entirely stifled, and progress was impossible. The whole field of religion and knowledge had become largely stagnant under an arbitrary despotism.
