Under the impulsion of Gregory and of Raymond of Pennaforte, Dominican inquisitors had at last been resorted to, and in this year, 1237, we first become cognizant of them. In right of his wife Ermessende, Roger Bernard the Great of Foix was Vizconde of Castelbo, a fief held of the Bishop of Urgel, with whom he had had a bitter war. He gave Castelbo to his son Roger, who, by the advice of his father, in 1237, allowed the Inquisition free scope there, placing the castle in the hands of Ramon Fulco, Vizconde of Cardona, in the name of the Archbishop of Tarragona and the bishops assembled at the Council of Lerida. That council thereupon appointed a number of inquisitors, including Dominicans and Franciscans, who made a descent on Castelbo. It had long been noted as a nest of Catharans. In 1225, under the protection of Arnaldo, then lord of the place, perfected heretics publicly preached their doctrines there. In 1234 we hear of a heretic of Mirepoix going thither to receive the _consolamentum_ on his death-bed. The inquisitors, therefore, had no difficulty in finding victims. They ordered two houses to be destroyed, exhumed and burned the bones of eighteen persons, condemned as heretics, and carried off as prisoners some forty-five men and women, condemned fifteen who fled, and were undecided about sundry others. Still, the Bishop of Urgel was not satisfied, and he gratified his rancor by condemning and excommunicating Roger Bernard as a defender of heretics, and it was not until 1240 that the latter, through the intervention of the Archbishop of Tarragona, and by submitting, abjuring heresy, and swearing to perform any penance assigned to him, procured from the bishop absolution and a certificate that he recognized him “_per bon et per leyal e per Catholich_.”[187]
In 1238 the Inquisition of Aragon may be said to be founded. In April of that year Gregory IX. wrote to the Franciscan Minister and Dominican Prior of Aragon deploring the spread of heresy through the whole kingdom, so that heretics no longer seek secrecy, but openly combat the Church, to the destruction of its liberties; and though this may be an exaggeration, we know from a confession before the Inquisition of Toulouse that there were enough scattered through the land to afford shelter to the wandering Catharan missionaries. Gregory, therefore, placed in the hands of the Mendicants the sword of the Word of God, which was not to be restrained from blood. They were instructed to make diligent inquisition against heresy and its abettors, proceeding in accordance with the statutes which he had issued, and calling in when necessary the aid of the secular arm. At the same time he made a similar provision for Navarre, which was likewise said to be swarming with heretics, by commissioning as inquisitors the Franciscan Guardian of Pamplona and the Dominican Pedro de Leodegaria. As an independent institution the Inquisition of Navarre seems never to have advanced beyond an embryonic condition. In 1246 we find Innocent IV. writing to the Franciscan Minister there to publish that Grimaldo de la Mota, a citizen of Pamplona, is not to be aspersed as a heretic because while in Lombardy he had eaten and drunk with suspected persons, but this is the only evidence of vitality that I have met with, and Navarre was subsequently incorporated into the Inquisition of Aragon.[188]
