But the Dominicans defied public opinion, the commission appointed by the pope, and the pope. They spoke of the pope as of a schoolboy under their authority. If he did not give a decision in their favor, they threatened to withdraw their allegiance, and desert him, even risking a rupture with the church. They went so far as to threaten that in case Reuchlin proved victorious, they would ally themselves with the Hussites in Bohemia against the pope. So blinded was this faction by revengeful feelings, that from sheer obstinacy they would undermine Catholicism. Nor did they spare the majesty of the emperor; when they learned that Maximilian had interceded for Reuchlin with the pope, they heaped abuse on him.

The Dominicans built their hopes on the verdict of Paris, the head of all European universities. If this important school of divinity condemned Reuchlin's writings and the Talmud, then even the pope would have to submit. Every influence was, therefore, brought to bear to obtain a favorable opinion from Paris. In particular, the king of France, Louis XII, was worked on by his confessor, Guillaume Haquinet Petit, to influence the school of divinity in favor of the Dominicans. The political events which had set the German emperor and the French king at variance were also brought into play. Because the emperor of Germany was for Reuchlin, the king of France decided for the Dominicans and against the Talmud. But this decision was not easily obtained, for Reuchlin numbered many warm friends in Paris. The consultation was prolonged from May to the beginning of August, 1514.

Many of the voters spoke in favor of Reuchlin and at the same time expressed their indignation at the unlawful proceedings; but they were cried down by the fanatics. Many French divines were guided by the example of Saint Louis, who, at the instigation of the baptized Jew, Nicholas Donin, and by command of Pope Gregory IX, had ordered the Talmud to be burnt three centuries before. The Parisian doctors, therefore, gave sentence that Reuchlin's "Augenspiegel," containing heresy, and defending with great zeal the Talmudic writings, deserved to be condemned to the flames, and the author to be forced to recant.

Great was the joy of the Dominicans, particularly those of Cologne, over this judgment. They believed their game to be won, and that the pope himself would be forced to submit. They did not delay in making known to the public this concession, so hardly won, by means of another libelous pamphlet.

The lawsuit, allowed to lag in Rome, was wilfully delayed still more by the Dominicans. The commission appointed had a close translation of the "Augenspiegel" prepared by a German in Rome, Martin von Grönigen; but the opposition found fault with it. Numerous hindrances blocked the progress of the suit, and at this stage cost Reuchlin 400 gold florins. The Dominicans had hoped so to impoverish their adversary, the friend of the Jews, that he would be incapacitated from obtaining justice. The prospect of seeing Reuchlin's cause triumphant at Rome diminished. Reuchlin's friends were, therefore, anxious to create another tribunal, and appeal from the badly advised or intimidated pope to public opinion.

During this tension of minds in small and great circles, whilst high and low ecclesiastics, princes and citizens, anxiously awaited news as to how the Reuchlin lawsuit had ended, or would end in Rome, a young Humanist (most likely Crotus Rubianus, in Leipsic), wrote a series of letters, which, for wit, humor and biting satire, had not been equaled in all literature. The "Letters of Obscurantists" (Epistolæ Obscurorum Virorum), published in 1515, in a great measure directed against the rascally Ortuinus Gratius, laid bare, in the language of the unpolished monks, their own baseness and insolence, their astonishing ignorance, their lust, their animosity and vileness, their despicable Latin, and still more contemptible morality, the absurdity of their logic, their foolish chatter—in short, all their intolerable vices were made so evident, and described so clearly, that even the half-educated could comprehend. All Reuchlin's enemies, Hoogstraten, Arnold von Tongern, Ortuinus Gratius, Pfefferkorn, their accomplices, and the Paris University, were lashed with whips and scorpions, so that no spot on them remained sound. This clever satire, containing more than Aristophanian scorn, made the stronger an impression as the Dominicans, the Thomists, the Doctors of Divinity, revealed themselves in their own persons, in their miserable meanness, placing themselves, metaphorically speaking, in the pillory. But it was inevitable that, in deriding the bigots and the papacy, the whole tyranny of the hierarchy and the church should be laid bare. For, were not the Dominicans, with their insolent ignorance and shameless vices, the product and natural effect of the Catholic order and institution? So the satire worked like a corroding acid, entirely destroying the already rotting body of the Catholic Church.

The Jews and the Talmud were the first cause of the Reuchlinist quarrel; naturally, they could not be left out of account in the letters of the Obscurantists. So it happened that the much despised Jews became one of the topics of the day.

A roar of laughter resounded through western Europe at the reading of these satirical letters. Everyone in Germany, Italy, France and England who understood Latin, was struck with the form and tenor of these confessions of Dominicans and scholastics. Their awkward vulgarity, dense stupidity, egregious folly, impurity of word and deed, stood so glaringly in contrast with their presumed learning and propriety, that the most serious men were moved to mirth. It is related that Erasmus, who, at the time of reading the letters, suffered from an abscess in the throat, laughed so heartily that it broke, and he was cured. The merry Comedy of the Fools put Reuchlin entirely in the right, and the Dominicans were judged by public opinion, no matter how the pope might deal with them. All were curious to know who could be the author. Some thought it was Reuchlin himself, others Erasmus, Hutten, or one of the Humanist party. Hutten gave the right answer to the question as to the author: "God himself." It appeared more and more clearly that so slight a cause as the burning of the Talmud had taken a world-wide significance, the will of the individual serving only to further the interests of all. In Rome and Cologne, far-seeing Reuchlinists discerned in it the work of Providence.

Only the German Jews could not indulge in merriment. The Dominicans had meantime worked in another way to obtain their object, or at least to have revenge on the Jews. Of what avail was it to the Jews that some enlightened Christians, having had their attention drawn to Judaism, were seized with so great a predilection for it that they gave expression to their new convictions in writing? Christendom as a whole was irrevocably prejudiced against Jewish teachings and their adherents. Erasmus rightly said, "If it is Christian to hate the Jews, then we are true Christians." Therefore, it was easy for their enemies to injure them. Pfefferkorn had often pointed out that there were in Germany only three great Jewish communities, at Ratisbon, Frankfort and Worms, and that with their extermination, Judaism in the German kingdom would come to an end.

To bring about the expulsion of the Jews from Frankfort and Worms, their enemies had discovered effective means. The young Margrave, Albert von Brandenburg, hitherto bishop of Magdeburg, who later attained melancholy renown in the history of the Reformation, had been elected to the archbishopric of Mayence. The enemies of the Jews, acting probably on a suggestion from Cologne, induced Archbishop Albert to issue an invitation to religious and secular authorities and to towns, principally Frankfort and Worms, to attend a diet in Frankfort, to discuss how the Jews might be banished and never be permitted to return. Obeying the invitation (January 7th, 1516), many deputies appeared. The program was to this purport: All the estates were to unite and take an oath to relinquish the privileges and advantages derived from the Jews, to banish all Jewish subjects and never, under any pretext, or for any term, permit them to return. This resolution was to be laid before the emperor for his confirmation.
