We see him, now fervidly urging a reluctant queen to do her duty by her God and unsheathe the sword of persecution, now harshly threatening his sovereigns with the wrath of Heaven when they are in danger of relenting in the wielding of that same sword. But in the main he must be studied, not in his actions, but in his enactments--the emanations of his relentless spirit. In these he is to be seen devoutly compassing evil in the perfervid quest of good. Untouched by worldly ambitions, he seems at once superhuman and less than human. Dauntless amid execrations, unmoved by plaudits, sublimely disdainful of temporal weal, in nothing is he so admirable as in the unfaltering self-abnegation with which he devotes himself to the service of his God, in nothing so terrible and tragically deplorable as in the actual service which he renders. “His history,” says Prescott, “may be thought to prove that of all human infirmities there is none productive of more extensive mischief to society than fanaticism.” To this day--four centuries after his passing--Spain still bears the imprint of his pitiless work, and none may deny the truth of Rosseuw St. Hilaire’s indictment that, after Philip II, Torquemada was the man who did most harm to the land that gave him birth. * * * * * The materials for this history have been gathered from the sources cited in the appended bibliography, to all of which the author acknowledges his profound indebtedness. In particular, however, are his thanks due--as must be the thanks of all men who engage in studies of the Spanish Inquisition--to the voluminous, succinct, and enormously comprehensive works of Juan Antonio Llorente, a historian of unimpugned honesty and authority, who wrote under circumstances peculiarly advantageous and with qualifications peculiarly full. * * * * * Juan Antonio Llorente was born at Logroño in 1756, and he was ordained priest in 1779, after a university course of Roman and Canon law which enabled him to obtain a place among the lawyers of the Supreme Council of Castile--_i.e._ the Council of the Inquisition. Having graduated as a Doctor of Canon Law, he discharged the duties of Vicar-General to the Bishop of Calahorra, and later on became the Commissary of the Holy Office in Logroño--for which it was necessary that he should prove that he was of “clean blood,” undefiled by the taint of Jew or Moor or heretic. In 1789 he was appointed Secretary-General to the Holy Office, an appointment which took him to Madrid, where he was well received by the King, who gave him a canonry of Calahorra.
