This was reason enough why Caietan, to avoid increasing the excitement, should not attempt to lay hands on the Wittenberg opponent of indulgences. The Elector Frederick, from whose hands Caietan would have to demand Luther, was one of the most powerful and personally respected princes of the Empire, and his influence was especially important in view of the election of a new Emperor. This prince went now in person to Caietan on Luther's behalf, and Caietan promised him, at the very time that the brief was on its way to him from Rome, that he would hear Luther at Augsburg, treat him with fatherly kindness, and let him depart in safety. Luther accordingly was sent to Augsburg. It was an anxious time for himself and his friends when he had to leave for that distant place, where the Elector, with all his care, could not employ any physical means for his protection, and to stand accused as a heretic before that Papal legate who, from his own theological principles, was bound to condemn him, Caietan being a zealous Thomist like Prierias, and already notorious as a champion of indulgences and Papal absolutism. 'My thoughts on the way,' said Luther afterwards, 'were now I must die; and I often lamented the disgrace I should be to my dear parents.' He went thither in humble garb and manner. He made his way on foot till within a short distance of Augsburg, when illness and weakness overcame him, and he was forced to proceed by carriage. Another younger monk of Wittenberg accompanied him, his pupil Leonard Baier. At Nüremberg he was joined by his friend Link, who held an appointment there as preacher. From him he borrowed a monk's frock, his own being too bad for Augsburg. He arrived here on October 7. The surroundings he now entered, and the proceedings impending over him, were wholly novel and unaccustomed. But he met with men who received him with kindness and consideration; several of them were gentlemen of Augsburg favourable to him, especially the respected patrician, Dr. Conrad Peutinger, and two counsellors of the Elector. They advised him to behave with prudence, and to observe carefully all the necessary forms, to which as yet he was a stranger. Luther at once announced his arrival to Caietan, who was anxious to receive him without delay. His friends, however, kept him back until they had obtained a written safe-conduct from the Emperor, who was then hunting in the environs. In the meantime, a distinguished friend of Caietan, one Urbanus of Serralonga, tried to persuade him, in a flippant, and, as Luther thought, a downright Italian manner, to come forward and simply pronounce six letters,--_Revoco_--I retract. Urbanus asked him with a smile if he thought his sovereign would risk his country for his sake. 'God forbid!' answered Luther. 'Where then do you mean to take refuge?' he went on to ask him. 'Under Heaven,' was Luther's reply.
