In addition to these the Kamerau family made claims upon the Jews of Ratisbon, as well as the town council, and, of course, the bishop. These contradictory and mutually hostile demands made the position of the Jews anything but a bed of roses. First from one side and then from another came orders to the council to imprison the Jews, their chiefs, or their rabbi, at that time the sorely-tried Israel Bruna, until, worn out by confinement, they decided to pay what was claimed. The council did indeed seek to shield them, but only so long as no danger threatened the citizens, or the Jews did not compete with the Christian guildmembers. To escape these cruel and arbitrary extortions, prudence directed that they place themselves under the protection of one of the Hussite nobles or captains. They would thus enjoy more security than was possible under the so-called protection of the emperor, since the fiery Hussites were not a little feared by the more sluggish Germans. Although they had to some extent abandoned their heretical fanaticism, and had taken service under the Catholic sovereigns, their desperate valor was still a source of terror to the orthodox clergy. The event proved that the Jews had acted wisely in appealing to their protection. A bishop named Henry was elected in Ratisbon, a man of gloomy nature, to whom the sentiment of mercy was unknown, and he naturally insisted on the enforcement of the canonical restrictions against the Jews. As examples to others, for instance, he mercilessly punished a Christian girl who had entered the service of a Jew, and a Christian barber who had let blood for a Jewish customer. His animosity was contagious. On one occasion, when the Jewish midwife was sick, and a Christian was about to attend some Jewish women, the council actually dared not give her the required permission without the episcopal sanction. Bishop Henry and Duke Louis, one in their hatred of Jews, now pursued what seemed to be a preconcerted plan for the ruin or conversion of the Jews of Ratisbon. On the one hand, they obtained the acquiescence of the pope, and on the other, the assistance of influential persons on the city council. Their campaign began with attempts at conversions and false accusations, for which they availed themselves of the assistance of a couple of worthless converted Jews. One of these, Peter Schwarz by name, wrote slanderous and abusive pamphlets against his former co-religionists. The other, one Hans Vayol, heaped the vilest calumnies upon the aged rabbi, Israel Bruna, amongst other things charging him with purchasing from him a seven-year-old Christian child and slaughtering it, and the rabbi of Ratisbon, already bowed down by sorrow and suffering, was charged with the death of the child.
