This was evidently a very cumbrous and costly method of dealing with heretics, but it does not appear that the Holy Office consented to delegate its powers until 1519, when Charles V, by a cédula of May 20th, confirmed the appointment by Cardinal Adrian the inquisitor-general, of Alfonso Manso, Bishop of Puertorico and the Dominican Pedro de Córdova, as inquisitors of the Indies, and ordered all officials to render them obedience and assistance.[387] On the death of Pedro, the appointing power is said to have vested in the Audiencia of San Domingo which, in 1524, appointed Martin de Valencia as commissioner. He was a Franciscan of high repute for holiness who in that year reached Mexico at the head of a dozen of his brethren and was received by the Conquistadores on their knees. We are told that he burnt a heretic and reconciled two others, which if true would show that he was clothed with the full powers of an inquisitor. He soon afterwards returned to Spain and we hear of Fray Tomás Ortiz, Fray Domingo de Betanzos and Fray Vicente de Santa María as succeeding him in 1526 and 1528, but the references to these shadowy personalities are conflicting and there are no records of their activity.[388] With the appointment of bishops in New Spain, in 1527, and the gradual systematic organization of the hierarchy, it would seem that special inquisitoral powers were delegated to them, of the results of which we have traces in the _sanbenitos_ or _tablillas_ of those burnt or reconciled which were hung in the cathedrals. Early in the nineteenth century Padre José Pichardo made a list of those remaining in the cathedral of Mexico, which has recently been printed and from this we learn that an auto de fe was celebrated in 1536, at which Andreas Morvan was reconciled for Lutheranism, and another in 1539, when Francisco Millan was reconciled for Judaism and a cacique of Tezcoco was burnt for offering human sacrifices.[389] This latter stretch of authority by Archbishop Zumárraga was contrary to the policy of the government and, in 1543, Inquisitor-general Tavera superseded him by sending Francisco Tello de Sandoval, inquisitor of Toledo, to Mexico to perform the same office. His commission, dated July 18th of that year, empowers him to take up and prosecute to the end all cases commenced by previous inquisitors, and a letter of Prince Philip, July 24th, to the royal officials of New Spain, commands them to give him all requisite assistance.[390] It does not appear, however, that he was furnished with officials to organize a tribunal and, as his principal charge was that of a _visitador_ or inspector of the ecclesiastical establishment, it is not probable that he accomplished much as inquisitor. The list of sanbenitos shows no more autos de fe until 1555, by which time the work had fallen back into the hands of Archbishop Montúfar, for the home Government was evidently unwilling to assume the heavy cost of a fully
