Bern was doing its best by embassies to assist them; but it dared not attack the Pays de Vaud when Freiburg, angry at the process of the Reformation, threatened a counter attack. After the siege was raised, the strongholds in the surrounding country remained in the possession of the enemy, and the people belonging to Geneva were liable to be pillaged and maltreated. Within the city the number of Evangelicals increased week by week. Then came a sensational event which brought about the ruin of the Roman Catholic party. A woman, Antonia Vax, cook in the house of Claude Bernard, with whom the three pastors dwelt, attempted to poison Viret, Farel, and Froment.[84] The confession of the prisoner, combined with other circumstances, created the impression among the members of Council and the people of Geneva that the priests of the town had instigated the attempt, and a strong feeling in favour of the Protestant pastors swept over the city. The Council at once provided lodging for Viret and Farel in the Convent of the Cordeliers. When the guardian of that convent asked leave to hold public discussions on religious questions in the great church belonging to the convent, it was at once granted. The Council itself made arrangements for the public Disputation. Five _Thèses évangéliques_ were drafted by the Protestant pastors, and the Council invited discussion upon them from all and sundry.[85] Invitations were sent to the canons of the cathedral, and to all the priests and monks of Geneva; safe-conducts were promised to all foreign theologians who desired to take part;[86] a special attempt was made to induce a renowned Paris Roman Catholic champion, Pierre Cornu, a theologian trained at the Sorbonne, who happened to be at Grenoble, to defend the Romanist position by attacking the _Theses_. The _Theses_ themselves were posted up in Geneva as early as the 1st of May (1535), and copies were sent to all the priests and convents within the territories of the Genevans.[87]
