A few days later the community at Cervera was attacked in a similar manner, eighteen of its members killed, and the rest compelled to flee. The Jewish philosopher, Vidal Narboni, happened to be in the town, and in the assault he lost his possessions and his books. All the congregations of northern Spain knew themselves in danger of being attacked; they instituted public fasts, implored mercy from heaven, and barricaded those of their quarters which were surrounded by walls. In Aragon, however, the higher classes came to the help of the Jews. Pope Clement VI, who had taken so much interest in the astronomical works of Gersonides, and who, terrified at the approach of death, had shut himself up in his room, still felt for the sufferings of an innocent, persecuted people. He issued a bull in which, under pain of excommunication, he prohibited anyone from killing the Jews without proper judicial sentence, or from dragging them by force to be baptized, or from despoiling them of their goods (the beginning of July). This bull was probably of some use in southern France, but in the other parts of the Christian world it produced no effect. One country followed the example of another. The ideally beautiful region surrounding Lake Geneva next became the scene of a most frightful persecution. At the command of Amadeus, duke of Savoy at that time, several Jews suspected of poisoning were arrested and imprisoned in two small towns, Chillon and Chatel, on Lake Geneva. A commission of judges was appointed to inquire into the charges brought against the prisoners, and, if convicted, they were to be severely punished. In this country, then, a prince and his tribunal believed the preposterous fable of the poisoning by Jews. On the Day of Atonement (15th September, 1348), three Jews and a Jewess in Chillon were made to undergo torture: the surgeon Valavigny, from Thonon, Bandito and Mamson, from Ville-Neuve, and, three weeks later, Bellieta and her son Aquet. In their pain and despair, they told the names of the persons from whom they had received the poison, and admitted that they had scattered it in different spots near wells and brooks. They denounced themselves, their co-religionists, their parents and their children as guilty. Ten days later the merciless judges again applied the torture to the enfeebled woman and her son, and they vied with each other in their revelations. In Chastelard five Jews were put to the torture, and they made equally incredible confessions of guilt. Aquet made the wild statement that he had placed poison in Venice, in Apulia and Calabria, and in Toulouse, in France. The secretaries took down all these confessions in writing, and they were verified by the signatures of their authors. To remove all doubts concerning their trustworthiness, the crafty judges added that the victims were only very lightly tortured. In consequence of these disclosures, not only the accused who
