The fable that the Inquisition was invoked to accomplish the death of Don Carlos, in 1568, has been sufficiently disproved to call for no attention here. There is probably, however, more truth in the statement that, about the same time, Philip II, in promotion of his designs on the remnants of Navarre, caused Inquisitor-general Espinosa to collect testimony as to the notorious heresy of Jeanne d'Albret and her children, and formed with the Guises a plot to abduct and deliver her to the tribunal of Saragossa, but the secret was not kept and the attempt was abandoned.[549] Perhaps, also, we may class with political service the utilization by Philip of the Inquisition to supply him with galley-slaves. The most prominent instance of the employment of the Inquisition in a matter of State was in the case of Antonio Pérez. Its dramatic character attracted the attention of all Europe; the mystery underlying it has never been completely dispelled, and its resultant effect upon the institutions of Aragon invests it with an importance justifying examination in some detail. Antonio Pérez was the brilliant and able favorite of Philip II, who in 1571 succeeded his patron, Ruy Gómez, Prince of Eboli, in acquiring his master's fullest confidence and becoming the most powerful subject in Spain. In 1573, the Venitian envoy Badoero describes him as a most accomplished man, whose courtesy and attractive manners soothed the sensibilities of those provoked by the delays and penuriousness of the king, while his dexterity and ability promised soon to make him the principal minister. At the same time, he was a man of pleasure and the magnificence of his daily life was the admiration of his countrymen.[550] He found his fate in the widow of his patron, the Princess of Eboli. Sprung from the noble house of Mendoza, she was proud, vindictive and passionate, unflinching in the gratification of her desires and reckless as to the means. Whether Philip II had been her lover, and if so whether he was favored or rejected, is a disputed question, which we need not discuss; it suffices that Pérez, who had a devoted wife in Juana Coello, became enamoured of her mature charms and a slave to her imperious will.
