From Alcala, Gasca was afterwards removed to Salamanca; where he distinguished himself by his skill in scholastic disputation, and obtained the highest academic honors in that ancient university, the fruitful nursery of scholarship and genius. He was subsequently intrusted with the management of some important affairs of an ecclesiastical nature, and made a member of the Council of the Inquisition.
In this latter capacity he was sent to Valencia, about 1540, to examine into certain alleged cases of heresy in that quarter of the country. These were involved in great obscurity; and, although Gasca had the assistance of several eminent jurists in the investigation, it occupied him nearly two years. In the conduct of this difficult matter, he showed so much penetration, and such perfect impartiality, that he was appointed by the Cortes of Valencia to the office of visitador of that kingdom; a highly responsible post, requiring great discretion in the person who filled it, since it was his province to inspect the condition of the courts of justice and of finance, throughout the land, with authority to reform abuses. It was proof of extraordinary consideration, that it should have been bestowed on Gasca; since it was a departure from the established usage - -and that in a nation most wedded to usage—to confer the office on any but a subject of the Aragonese crown.6
Gasca executed the task assigned to him with independence and ability. While he was thus occupied, the people of Valencia were thrown into consternation by a meditated invasion of the French and the Turks, who, under the redoubtable Barbarossa, menaced the coast and the neighboring Balearic isles. Fears were generally entertained of a rising of the Morisco population; and the Spanish officers who had command in that quarter, being left without the protection of a navy, despaired of making head against the enemy. In this season of general panic, Gasca alone appeared calm and self-possessed. He remonstrated with the Spanish commanders on their unsoldierlike despondency; encouraged them to confide in the loyalty of the Moriscos; and advised the immediate erection of fortifications along the shores for their protection. He was, in consequence, named one of a commission to superintend these works, and to raise levies for defending the sea-coast; and so faithfully was the task performed, that Barbarossa, after some ineffectual attempts to make good his landing, was baffled at all points, and compelled to abandon the enterprise as hopeless. The chief credit of this resistance must be assigned to Gasca, who superintended the construction of the defences, and who was enabled to contribute a large part of the requisite funds by the economical reforms he had introduced into the administration of Valencia.7
It was at this time, the latter part of the year 1545, that the council of Philip selected Gasca as the person most competent to undertake the perilous mission to Peru.8 His character, indeed, seemed especially suited to it. His loyalty had been shown through his whole life. With great suavity of manners he combined the most intrepid resolution. Though his demeanor was humble, as beseemed his calling, it was far from abject; for he was sustained by a conscious rectitude of purpose, that impressed respect on all with whom he had intercourse. He was acute in his perceptions, had a shrewd knowledge of character, and, though bred to the cloister, possessed an acquaintance with affairs, and even with military science, such as was to have been expected only from one reared in courts and camps.
Without hesitation, therefore, the council unanimously recommended him to the emperor, and requested his approbation of their proceedings. Charles had not been an inattentive observer of Gasca's course. His attention had been particularly called to the able manner in which he had conducted the judicial process against the heretics of Valencia.9 The monarch saw, at once, that he was the man for the present emergency; and he immediately wrote to him, with his own hand, expressing his entire satisfaction at the appointment, and intimating his purpose to testify his sense of his worth by preferring him to one of the principal sees then vacant.
Gasca accepted the important mission now tendered to him without hesitation; and, repairing to Madrid, received the instructions of the government as to the course to be pursued. They were expressed in the most benign and conciliatory tone, perfectly in accordance with the suggestions of his own benevolent temper.10 But, while he commended the tone of the instructions, he considered the powers with which he was to be intrusted as wholly incompetent to their object. They were conceived in the jealous spirit with which the Spanish government usually limited the authority of its great colonial officers, whose distance from home gave peculiar cause for distrust. On every strange and unexpected emergency, Gasca saw that he should be obliged to send back for instructions. This must cause delay, where promptitude was essential to success. The Court, moreover, as he represented to the council, was, from its remoteness from the scene of action, utterly incompetent to pronounce as to the expediency of the measures to be pursued. Some one should be sent out in whom the king could implicitly confide, and who should be invested with powers competent to every emergency; powers not merely to decide on what was best, but to carry that decision into execution; and he boldly demanded that he should go not only as the representative of the sovereign, but clothed with all the authority of the sovereign himself. Less than this would defeat the very object for which he was to be sent. "For myself," he concluded, "I ask neither salary nor compensation of any kind. I covet no display of state or military array. With my stole and breviary I trust to do the work that is committed to me.11 Infirm as I am in body, the repose of my own home would have been more grateful to me than this dangerous mission; but I will not shrink from it at the bidding of my sovereign, and if, as is very probable, I may not be permitted again to see my native land, I shall, at least, be cheered by the consciousness of having done my best to serve its interests." 12
The members of the council, while they listened with admiration to the disinterested avowal of Gasca, were astounded by the boldness of his demands. Not that they distrusted the purity of his motives, for these were above suspicion. But the powers for which he stipulated were so far beyond those hitherto delegated to a colonial viceroy, that they felt they had no warrant to grant them. They even shrank from soliciting them from the emperor, and required that Gasca himself should address the monarch, and state precisely the grounds on which demands so extraordinary were founded.
Gasca readily adopted the suggestion, and wrote in the most full and explicit manner to his sovereign, who had then transferred his residence to Flanders. But Charles was not so tenacious, or, at least, so jealous, of authority, as his ministers. He had been too long in possession of it to feel that jealousy; and, indeed, many years were not to elapse, before, oppressed by its weight, he was to resign it altogether into the hands of his son. His sagacious mind, moreover, readily comprehended the difficulties of Gasca's position. He felt that the present extraordinary crisis was to be met only by extraordinary measures. He assented to the force of his vassal's arguments, and, on the sixteenth of February, 1546, wrote him another letter expressive of his approbation, and intimated his willingness to grant him powers as absolute as those he had requested.
Gasca was to be styled President of the Royal Audience. But, under this simple title, he was placed at the head of every department in the colony, civil, military, and judicial. He was empowered to make new repartimientos, and to confirm those already made. He might declare war, levy troops, appoint to all offices, or remove from them, at pleasure. He might exercise the royal prerogative of pardoning offences, and was especially authorized to grant an amnesty to all, without exception, implicated in the present rebellion. He was, moreover, to proclaim at once the revocation of the odious ordinances. These two last provisions might be said to form the basis of all his operations.
Since ecclesiastics were not to be reached by the secular arm, and yet were often found fomenting troubles in the colonies, Gasca was permitted to banish from Peru such as he thought fit. He might even send home the viceroy, if the good of the country required it. Agreeably to his own suggestion, he was to receive no specified stipend; but he had unlimited orders on the treasuries both of Panama and Peru. He was furnished with letters from the emperor to the principal authorities, not only in Peru, but in Mexico and the neighboring colonies, requiring their countenance and support; and, lastly, blank letters, bearing the royal signature, were delivered to him, which he was to fill up at his pleasure.13
