Philip, far from taking umbrage at the swelling tone of this apostolical mandate, followed it up, in the same year, by a monstrous edict, borrowed from one in the Netherlands, which condemned all who bought, sold, or read prohibited works to be burned alive. In the following January, Paul, to give greater efficacy to this edict, published another bull, in which he commanded all confessors, under pain of excommunication, to enjoin on their penitents to inform against all persons, however nearly allied to them, who might be guilty of such practices. To quicken the zeal of the informer, Philip, on his part, revived a law fallen somewhat into disuse, by which the accuser was to receive one fourth of the confiscated property of the convicted party. And finally, a third bull from Paul allowed the inquisitors to withhold a pardon from the recanting heretic, if any doubt existed of his sincerity; thus placing the life as well as fortune of the unhappy prisoner entirely at the mercy of judges who had an obvious interest in finding him guilty. In this way the pope and the king continued to play into each other's hands, and while his holiness artfully spread the toils, the king devised the means for driving the quarry into them.[436] Fortunately for these plans, the Inquisition was at this time under the direction of a man peculiarly fitted to execute them. This was Fernando Valdés, cardinal-archbishop of Seville, a person of a hard, inexorable nature, and possessed of as large a measure of fanaticism as ever fell to a grand-inquisitor since the days of Torquemada. Valdés readily availed himself of the terrible machinery placed under his control. Careful not to alarm the suspected parties, his approaches were slow and stealthy. He was the chief of a tribunal which sat in darkness, and which dealt by invisible agents. He worked long and silently under ground before firing the mine which was to bury his enemies in a general ruin. [Sidenote: SUPPRESSION OF THE REFORM.] His spies were everywhere abroad, mingling with the suspected, and insinuating themselves into their confidence. At length, by the treachery of some, and by working on the nervous apprehensions or the religions scruples of others, he succeeded in detecting the lurking-places of the new heresy, and the extent of ground which it covered. This was much larger than had been imagined, although the Reformation in Spain seemed less formidable from the number of its proselytes than from their character and position. Many of them were ecclesiastics, especially intrusted with maintaining the purity of the faith. The quarters in which the heretical doctrines most prevailed were Aragon, which held an easy communication with the Huguenots of France, and the ancient cities of Seville and Valladolid, indebted less to any local advantages than to the influence of a few eminent men, who had early embraced the faith of the Reformers.
