Impenetrable secrecy was one of the most cherished principles of inquisitorial procedure, but Lucero probably desired to prepare the public for the impending blow and whispers concerning it began to circulate. Peter Martyr of Anghiera, who was attached to the royal court, wrote on January 3, 1506, to the Count of Tendilla, Governor of Granada, that Lucero, by means of witnesses under torture, had succeeded in imputing Judaism to the archbishop and his whole family and household; as there was no one more holy than Talavera, he found it difficult to believe that any one could be found to fabricate such a charge.[542] The attack commenced by arresting, in the most public and offensive manner, Talavera's nephew, the dean and the officials of his church, during divine service and in his presence, evidently with the purpose of discrediting him. The arrest followed of his sister, his nieces and his servants, and we can readily conceive the means by which even his kindred were compelled to give evidence incriminating him, as we gather from a letter of Ferdinand, June 9, 1506, to his ambassador at Rome, Francisco de Rojas, in which he says that the testimony against Talavera is that of his sisters and kindred and servants.[543] Before he could be arrested and prosecuted, however, special authorization from the Holy See was requisite, for, by a decree of Boniface VIII, inquisitors had no direct jurisdiction over bishops. For this, Ferdinand's intervention was necessary and, after some hesitation, he consented to make the application. The inculpatory evidence given by Talavera's family was sent to Rome; Francisco de Rojas procured the papal commission for his trial and forwarded it, June 3, 1506.[544]
