This accomplished little, however, and, after their enforced conversion, the Moriscos continued to enjoy the reputation of masters of the black arts.[391] [Sidenote: _INQUISITORIAL JURISDICTION_] In the kingdoms of Aragon the secular power seems to have been negligent, and the duty reverted to the episcopate, which was for the most part indifferent. It was not wholly so, however, for, in 1372, Pedro Clasquerin, Archbishop of Tarragona, ordered an investigation of his province by _testes synodales_, and among the matters to be inquired into was whether there were sorcerers. Even Inquisitor Eymerich appears to consider it as in no way the business of the Holy Office, when he seeks to impress upon all bishops the duty of searching for such enemies of Christ, and of punishing them with all severity.[392] In Castile, while all the arts of sorcery were reckoned heretical, jurisdiction over them remained secular, even after the establishment of the Inquisition although, among Isabella's good qualities, is enumerated her exceeding abhorrence of diviners and sorcerers and all practitioners of similar arts.[393] There was evidently no thought of diverting the Inquisition from its labors among the New Christians, when a royal decree of 1500 ordered all corregidors and justicias to investigate as to the existence in their districts of diviners and such persons, who were to be arrested and punished if laymen, while if clerics they were to be handed over to their prelates for due castigation.[394]
