In dealing with a people whose liberties were so extensive and whose jealousy as to their maintenance was so sensitive, Ferdinand was far too shrewd to provoke opposition by the abrupt introduction of the Inquisition such as he had forced upon Castile. His first endeavor naturally was to utilize the institution as it had so long existed. This, although founded as early as 1238, had sunk into a condition almost dormant in the spiritual lethargy of the century preceding the Reformation, and in Aragon, as in the rest of Europe, it appeared to be on the point of extinction. It is true that, in 1474, Sixtus IV had ordered Fra Leonardo, the Dominican General, to fill all the tribunals of the Holy Office and he had complied by appointing Fray Juan as Inquisitor of Aragon, Fray Jaime for Valencia, Fray Juan for Barcelona and Fray Francisco Vital for Catalonia, but we have no record of their activity.[607] So little importance, indeed, was attached to the functions of the Inquisition that in Valencia, where in 1480 the Dominicans Cristóbal de Gualbes and Juan Orts were inquisitors, they held faculties enabling them to act without the concurrence of the episcopal representative--an unexampled privilege, only explicable on the assumption that the archbishop declined to be troubled with matters so trivial. The archbishop at the time was Cardinal Rodrigo Borgia, papal vice-chancellor, better known as Alexander VI, who speedily woke up to the speculative value of his episcopal jurisdiction over heresy, when the fierce persecution, which arose in Andalusia in January, 1481, with its attendant harvest of fines and compositions, showed that a similar prospect might be anticipated in his own province. Accordingly a brief of Sixtus IV, December 4, 1481, addressed to the inquisitors, withdrew their faculties of independent action and went to the other extreme by directing them in future to do nothing without the concurrence of the vicar-general, Mateo Mercader, senior archdeacon of Valencia.[608] [Sidenote: _REVIVAL OF OLD INQUISITION_]
