The education which Erasmus received at Deventer was still in thraldom to the mediaeval ideal. Greek was practically unknown, and in Latin all that was required of the student was a sufficient mastery of the rudiments of grammar to enable him to express somehow the distinctions and refinements of thought for which he was being trained. Niceties of scholarship and amplitude of vocabulary were unnecessary to him and were disregarded. From a material point of view also education was hampered. Printing was only just beginning, and there were few, if any, schoolbooks to be had. Lectures and lessons still justified their name 'readings'; for the boys sat in class crowded round their master, diligently copying down the words that fell from his lips, whether he were dictating a chapter in grammar, with its rules of accidence and syntax, or at a later stage a passage from a Latin author with his own or the traditional comments. Their canon of the classics was widely different from ours; instead of the simplified Caesar or Ovid that is now set before the schoolboy, Terence occupied a principal position, being of the first importance to an age when the learned still spoke Latin. Portions of the historians were read, for their worldly wisdom rather than for their history; Pliny the Elder for his natural science, and Boethius for his mathematics; and for poetry Cato's moral distiches and Baptista of Mantua, 'the Christian Vergil.' In this atmosphere Erasmus's early years were spent; but from some of his masters he caught the breath of the new life that came from Italy, and this he never lost. By 1485, shortly after he had left Deventer, both his parents were dead, and a few years later he was persuaded to enter the monastery of Steyn, near Gouda, a house of Augustinian canons. The life there was uncongenial to him; for though he had leisure to read as much as he liked, his temperament was not suited to the precision and regularity of religious observance. An opportunity for escape presented itself, when the Bishop of Cambray, a powerful ecclesiastic, was inquiring for a Latin secretary. Erasmus, who had already become very facile with his pen, obtained the post and for a year or more discharged its duties.
