In 1292 we hear of persecutions in the Val Perosa, and again in 1312 there were burnings of obstinate heretics in the valleys, but these efforts effected little, for in 1332 a brief of John XXII. describes the Waldensian church of the diocese of Turin as being in a most flourishing condition. The heretics were so numerous that they disdained concealment, holding assemblies in public in which as many as five hundred would be gathered together. When Frà Giovanni Alberto, the Inquisitor of Turin, had recently made an effort to repress them, they boldly rose in arms. On the public square of Angrogna they slew the parish priest Guillelmo, whom they suspected of furnishing information, and Alberto himself they besieged in a castle where he had taken refuge, so that he was glad to escape with his life, leaving the land abandoned to heresy. For twenty years and more one of their principal chiefs had been a man named Pier Martino, known also as Giuliano or Martino Pastrae, who chanced in his wandering missions to fall into the hands of Jean de Bades, the Inquisitor of Provence. The pope thereupon orders the latter to deliver his prisoner to Frà Alberto, who will be able to extract from him information of the utmost value in tracking and seizing his fellow-religionists--information, as the pope suggests, which will justify the use of torture. Doubtless this lucky capture enabled Frà Alberto to lay hands on a number of outlying heretics, though he probably did not again venture his person in the populous communities which had shown so sturdy a readiness in self-protection.[293] Persecution continued, and in 1354 we chance to hear of an order issued by Giacomo, Prince of Piedmont, to the Counts of Luserna, to imprison a number of Waldenses recently discovered in Luserna and the neighboring valleys. The order was issued at the instance of Pietro di Ruffia, Inquisitor of Piedmont, who paid for his zeal with his life, being shortly afterwards slain at Susa. In 1363 and 1364 Urban V. made another attempt to reduce the heretics to obedience. The infected district was exposed to attack on both sides, for the jurisdiction of the Inquisitor of Provence extended over the Tarantaise. Frère Jean Richard of Marseilles was directed to assail them from the west, while the inquisitor and the Bishop of Turin were busy on the east. Amadeo of Savoy was requested to co-operate with the Seneschal of Provence, and this combined assault resulted in a number of captures and trials. It was doubtless the mingled despair and thirst for revenge excited by this that led to many Waldenses joining in the rising of the Jacquerie in Savoy in 1365--a rising which was suppressed with the customary merciless cruelty by the King of Navarre and Wenzel of Brabant. In spite of these efforts at repression a letter written by them in 1368, to their German brethren, would seem to show that they were still regarded as the leaders of the sect.[294]
