The scale at length seemed to turn with the advent on the scene of the Mendicant Orders, full of the irrepressible enthusiasm, the disregard of toil and hardship, and the thirst for martyrdom of which we have already seen so many examples. Behind them now, moreover, was Gregory IX., the implacable and indefatigable persecutor of heresy, who urged them forward unceasingly. The Dominicans were first upon the ground. As early as 1221 the Order formed establishments in Hungary, developing its proselyting energy from that centre, and thus taking the heretics in flank. The Dominican legend relates that the Inquisition was founded in Hungary by Friar Jackzo (St. Hyacinth), an early member of the Order, who died in 1257, and that it could soon boast of two martyred inquisitors, Friar Nicholas, who was flayed alive, and Friar John, who was lapidated by the heretics. In 1233 we hear of the massacre of ninety Dominican missionaries among the Cumans, and it was perhaps somewhat earlier than this that thirty-two were drowned by the Bosnian heretics, whom they were seeking to convert; but Dominican ardor was only inflamed by such incidents. Preparations were made for systematic work. In 1232 Gregory ordered his legate in Hungary, Giacopo, Bishop of Palestrina, to convert the Bosnians. King Andreas gave the Banate to his son Coloman, Duke of Croatia and Dalmatia, and ordered him to assist. Results soon followed. The Catholic Bishop of Bosnia was himself infected with heresy, and excused himself on the ground that he had ignorantly supposed the Cathari to be orthodox. The Archbishop of Ragusa was cognizant of this, and had paid no attention to it, so Giacopo transferred Bosnia to Kalocsa--a transfer, however, which was for the present inoperative. More important was the conversion of Ninoslav, who abandoned the religion of his fathers in order to avert the attacks of Coloman, which were rapidly dismembering his territories. He was effusively welcomed by Gregory; he gave money to the Dominicans for the building of a cathedral; many of his magnates followed his example, and his kinsman, Uban Prijesda, handed his son to the Dominicans as a hostage for the sincerity of his conversion. Gregory was overjoyed at this apparent success. In 1233 he ordered the boy restored to his father; he took Bosnia under the special protection of the Holy See, and ordered Coloman to defend Ninoslav from the attacks of disaffected heretics; he deposed the heretic bishop, and instructed his legate to divide the territory into two or three sees, appointing proper incumbents. The latter measure was not carried out, however, and a German Dominican, John of Wildeshausen, was consecrated Bishop of all Bosnia.[328]
