ALTHOUGH Catharism never obtained in the North sufficient foothold to render it threatening to the Church, yet the crusades and the efforts which followed the pacification of 1229 must have driven many heretics to seek refuge in places where they might escape suspicion. In organizing persecution in the South, therefore, it was necessary to provide some supervision more watchful than episcopal negligence was likely to supply, over the regions whither heretics might fly when pursued at home, or the efforts made in Languedoc would only be scattering the infection. Vigilant guardians of the faith were consequently requisite in lands where heretics were few and hidden, as well as in those where they were numerous and enjoyed protection from noble and city. Under the pious king, St. Louis, who declared that the only argument a layman could use with a heretic was to thrust a sword into him up to the hilt, they were sure of ample support from the secular power.[125]
Accordingly when, in 1233, the experiment was tried of appointing Pierre Cella and Guillem Arnaud as inquisitors in Toulouse, a similar tentative effort was made in the northern part of the kingdom. Here also it was the Dominican Order which was called upon to furnish the necessary zealots. I have already alluded to the failure of the attempt to induce the Friars of Franche-Comté to undertake the work. In western Burgundy, however, the Church was more fortunate in finding a proper instrument. Like Rainerio Saccone, Frère Robert, known asle Bugre, had been a Patarin. The peculiar fitness thence derived for detecting the hidden heretic was rendered still more effective by the special gift which he is said to have claimed, of being able to recognize them by their speech and carriage. In addition, he was fitted for the work by the ardent fanaticism of the convert, by his learning, his fiery eloquence, and his mercilessness. When, early in 1233, instructions to persecute heresy were sent to the Prior of Besançon, Robert was nominated to represent him and act as his substitute; and, eager to manifest his zeal, he lost no time in making a descent upon La Charité. It will be remembered that this place was notorious as a centre of heresy in the twelfth century, and that repeated efforts had been made to purify it. These had proved fruitless against the stubbornness of the misbelievers, and Frère Robert found Stephen, the Cluniac prior, vainly endeavoring to win or force them over. The new inquisitor seems to have been armed with no special powers, but his energy speedily made a profound impression, and heretics came forward and confessed their errors in crowds, husbands and wives, parents and children, accusing themselves and each other without reserve. He reported to Gregory IX. that the reality was far worse than had been rumored; that t
