that they should be masters in theology.[621] During the interval, prior to this extension of Torquemada's jurisdiction, there was an incident showing that Sixtus had yielded the appointment of inquisitors, while endeavoring to retain the power of dismissing them. Cristóbal Gualbes, who was acting in Valencia to the entire satisfaction of Ferdinand, became involved in a bitter quarrel with the Archdeacon Mercader for whom, as we have seen, Cardinal Borgia had obtained a papal brief, virtually constituting him an indispensable member of the tribunal--a power which he doubtless used speculatively to the profit of Borgia and himself. It is to the interference of Gualbes with these worthies that we may reasonably attribute the action of Sixtus, who wrote, May 25, 1483, to Ferdinand and Isabella that the misdeeds of Gualbes merited heavy punishment, but he contented himself with removing him and asked them to fill his place with some fitting person on whom he in advance conferred the necessary powers. He evidently felt doubtful as to their acquiescence, for he wrote on the same day to Iñigo Archbishop of Seville, asking him to use his influence to induce the sovereigns to concur in this.[622] Ferdinand was not inclined to abandon Gualbes for, in a letter of August 8th, he orders the Maestre Racional of Valencia to pay to "lo devot religios maestre Gualbes" forty libras to defray his expenses in coming to the king at Córdova and in order that he might without delay return to work.[623] In the final settlement however Gualbes was sacrificed, for when Torquemada was made Inquisitor-general of Aragon, Sixtus expressly forbade him from appointing that son of iniquity Cristóbal Gualbes who, for his demerits, had been interdicted from serving as inquisitor.[624] * * * * * If Ferdinand imagined that he had overcome the resistance of his subjects by placing them under the Castilian Inquisition with Torquemada at its head, he showed less than his usual sagacity. They had been restive under the revived institution conducted by their own people and the intense particularism of the Aragonese could not fail to arouse still stronger opposition to the prospect of subjection to the domination of a foreigner such as Torquemada, whose sinister reputation for pitiless zeal gave assurance that the work would be conducted with greater energy than ever.
