"We have heard," he wrote to Henry IV, "that the baptized Jews have been permitted to leave the Church. This is unexampled and sinful; and we demand of all our brethren that they take care that the sacrament of the Church be not desecrated by the Jews." The emperor cared but little about the unholy zeal of the priesthood. Far from forbidding the Jews to return to their religion, he even permitted proceedings to be instituted against the kinsmen of Archbishop Ruthard, of Mayence, on account of the theft of the property of the Jewish congregation. The Jews of Mayence in a petition had informed the emperor that Emmerich of Leiningen and his kinsmen, together with the archbishop, had appropriated the treasures deposited by the Jews in the archbishop's palace. None of the accused appeared in answer to this citation to defend himself. Ruthard, whose conscience was not clear, feared the disgrace of exposure, and, as he was in disfavor with the emperor, he fled to Erfurt. Thereupon the emperor confiscated the revenues of the archbishopric (1098). Ruthard revenged himself by joining the enemies of the emperor, who plotted to humiliate him. The Jews of Bohemia were very unfortunate in this year. Hearing that the emperor had permitted return to Judaism, they abandoned their pretended faith, but feared to remain in a country where they could not obtain justice. They gathered together their property and possessions in order to send them on to a place of safety, and determined to emigrate to Poland or to Pannonia (Austria and Hungary). Wratislaw, the ruler of Bohemia, now returned from his campaign, and heard that the Jews intended sending their riches out of the country. Thereupon he placed them under military surveillance. The elders were called together, and the duke's treasurer announced to them in his lord's name that everything they possessed belonged to him, and that they were endeavoring to rob him: "Ye brought none of Jerusalem's treasures to Bohemia. Conquered by Vespasian, and sold for a mere nothing, ye have been scattered over the globe. Naked ye have entered the land, and naked ye can depart. For your secession from the Church, Bishop Cosmas may judge you." There was nothing to be said against this logic; it was the argument of brutality. The Bohemian Jews were plundered, only enough being left to them to stay for the moment the cravings of hunger. With malicious pleasure a contemporary chronicler relates that the Jews were despoiled of more gold than the Greeks had taken from Troy. Still more dreadful was the fate of the Jews of Jerusalem. When the crusading army, under Godfrey of Bouillon, after many attempts had taken the city by storm, and massacred the Mahometans, they drove the Jews, Rabbanites and Karaites, into a synagogue, set fire to it, and burnt all within its walls (July 15, 1099).
