If he thus controlled appointments he was equally concerned in dismissals. We find him writing, April 22, 1498, to an inquisitor of Saragossa, who had discharged an official at Calatayud, to reinstate him, as he had done good service with danger to his person, and on September 19, 1509, ordering Diego López de Cortegano, Inquisitor of Córdova, to cease his functions at once and return to his benefice--though this latter order was countersigned by the members of the Suprema.[732] It would be superfluous to adduce additional examples of the control thus exercised over the personnel of the Inquisition--a control which remained inherent in the crown although, as we shall see, often allowed to become dormant. In all save spiritual matters, Ferdinand considered the Inquisition to be merely an instrument to carry out his will, though it must be added that this arose from his anxiety that it should be perfected in every way for the work in hand, and there is absolutely no evidence, in his enormous and confidential correspondence, that he ever used it for political purposes, even in the stormiest times when struggling with unruly nobles. Every detail in its organization and working was subject to his supervision and, amid all the cares of his tortuous policy, extending throughout Western Europe, and the excitement of his frequent wars, he devoted the minutest care to its affairs. When, in December 1484, Torquemada issued his supplementary instructions, he was careful to state that he did so by command of the sovereigns, who ordered them to be observed. So in subsequent instructions, issued in 1485, Torquemada orders the inquisitors to write to him and to Ferdinand about everything that should be reported; the king provides their salaries promises them rewards; if there is anything that the king ought to remedy he is to be written to.[733] That, in fact, the was recognized as controlling the Inquisition is seen in all the efforts of the Córtes, appealing to him to obtain a modification of its rigors, although, as we have seen, the Concordia of 1512 was held to require the assent of Inquisitor-general Enguera to render it binding, with subsequent confirmation by the pope and though, in later times, the monarchs found it convenient to throw upon the inquisitor-general the responsibility of rejecting the demands of their subjects.
