At Oxford, then, the great centre of theological study, he was learning something of the methods of the theologians. They were not strange to him, for he knew Paris. But the Oxford school was in his mind when he poured forth his shafts of ridicule upon scholastic divines in his brilliant satire, "The Praise of Folly." Yet it was at Oxford that Colet had taught him to detest the authority of Thomas Aquinas, and to apply to the study of the New Testament the knowledge and methods indicated by the study of Greek literature. His "Moria" and his "Novum Instrumentum," therefore, the books which prepared the way for the Reformation, were his protest, and the protest of the Christian laity along with him, against the authority of the clergy and against the popular theology which was based on the errors of the Vulgate. Erasmus laid the egg and Luther hatched it--a very different bird, as the former declared. The fact was that throughout Europe the growing intelligence of the educated class was slowly but surely developing in antagonism, not merely to specific doctrines, but to the whole spirit of mediæval theology. The Old Learning was threatened with destruction. It rose in arms against Greek and heresy. Bishops fulminated. The clergy cried Antichrist, and clamoured for sword and faggot. The Universities forbade the sale of Erasmus's writings, and, seeing what came of the study of Greek, declared that they would have no more of it. Oxford divided itself into two bodies, who called themselves Greeks and Trojans, the Trojans enormously preponderating. The "Greeks," the adherents of the New Learning, were assailed with every kind of ridicule. They were openly derided in the streets and abused from the pulpit. In after years Tyndale, who had been a student at Magdalen Hall, could recall how "The old barking curs, Duns' disciples and like draff called Scotists, the children of darkness, raged in every pulpit against Greek, Latin and Hebrew, and what sorrow the schoolmasters that taught the true Latin tongue had with them, some beating the pulpit with their fists for madness, and roaring out with open and foaming mouth, that if there were but one Terence or Vergil in the world, and that same in their sleeve, and a fire before them, they would burn them therin, though it should cost them their lives." News of what was going on reached the court at Abingdon. At the King's command, More wrote to the governing body of the University to rebuke the intemperance of the Trojan clique. But the Heads of Houses were sleeping over a volcano, and More's letter could not rouse them from their slumber. For the present the result was that the little band of pioneers in the New Learning one by one departed out of their coasts.
