I have established the truth of that which concerns the Emperor Charles V.; Jeanne of Albret, queen of Navarre; Henry IV., king of France, her son, and of Margaret of Bourbon, the sovereign duchess of Bar, her daughter; of Don James of Navarre, son of Don Carlos, prince of Biana, surnamed the Infant of Tudela; of John Pic de Mirandola; of Don John of Austria, son of Philip IV.; of Alexander Farnèse, duke of Parma, and grandson of Charles V.; Don Philip of Arragon, son of the Emperor of Morocco; of Cæsar Borgia, son of Pope Alexander VI., and relation of the king of Navarre; of Jean Albret, duke of Valentinois, peer of France; of Don Peter Louis Borgia, last grand-master of the military order of Montessa, and of many other princes against whom the Inquisition exercised its power. The lover of history will find the details of the trials of seven archbishops, twenty bishops, and a great number of learned men, among whom are many of the members of the Council of Trent, who were unfortunately suspected of entertaining or favouring the Lutheran doctrines. To this list I have added the suits instituted by the _holy office_ against many _saints_, and other personages, held in reverence by the Church of Spain, and also of many literati persecuted by this tribunal. These, for the sake of perspicuity, I have divided into two classes; the first class comprises those learned theologians who were accused of Lutheranism, for having, in their zeal, corrected the text of Bibles already published, or Latin translations from the Greek and Hebrew editions. The second class consists of those learned men, designated by the holy office under the title of False Philosophers, and who were persecuted for having manifested a wish to destroy, in Spain, superstition and fanaticism.
