At last, a little before Luther's public appearance, a conflict occurred between the "poets," as the humanists were fond of calling themselves, and the "barbarians," as they called the theologians and monkish writers. An eminent Hebrew scholar, Reuchlin, had become involved in a bitter controversy with the Dominican professors of the University of Cologne. His cause was championed by the humanists, who prepared an extraordinary satire upon their opponents. They wrote a series of letters, which were addressed to one of the Cologne professors and purported to be from his former students and admirers. In these letters the writers take pains to exhibit the most shocking ignorance and stupidity. They narrate their scandalous doings with the ostensible purpose of obtaining advice as to the best way to get out of their scrapes. They vituperate the humanists in comically bad Latin, which is perhaps the best part of the joke.[269] In this way those who later opposed Luther and his reforms were held up to ridicule in these letters and their opposition to progress seemed clearly made out.

No other man of letters, unless it be Voltaire, has ever enjoyed such a European reputation during his lifetime. He was venerated by scholars far and wide, even in Spain and Italy. Although he was born in Rotterdam he was not a Dutchman, but a citizen of the world; he is, in fact, claimed by England, France, and Germany. He lived in each of these countries for a considerable period and in each he left his mark on the thought of the time. Erasmus, like most of the northern humanists, was deeply interested in religious reform, and he aspired to give the world a higher conception of religion and the Church than that which generally prevailed. He clearly perceived, as did all the other intelligent people of the time, the vices of the prelates, priests, and especially of the monks. Against the latter he had a personal grudge, for he had been forced into a monastery when he was a boy, and always looked back to the life there with disgust. Erasmus reached the height of his fame just before the public appearance of Luther; consequently his writings afford an admirable means of determining how he and his innumerable admirers felt about the Church and the clergy before the opening of the great revolt.
