Accompanied by Cesare and some cardinals and gentlemen of his following, he went to the Church of St.Dominic and was conducted to the sister's cell by the Prior--the same who in Cesare's student-days had refused to have the bells rung.
Upon seeing the magnificent figure of the Pontiff filling the doorway of her little chamber, Sister Colomba fell at his feet, and, taking hold of the hem of his gown, she remained prostrate and silent for some moments, when at last she timidly arose.

Alexander set her some questions concerning the Divine Mysteries.

These she answered readily at first, but, as his questions grew, she faltered, became embarrassed, and fell silent, standing before him white and trembling, no doubt a very piteous figure.

The Pope, not liking this, turned to the Prior to demand an explanation, and admonished him sternly: "Caveto, Pater, quia ego Papa sum!" This had the effect of throwing the Prior into confusion, and he set himself to explain that she was in reality very wonderful, that he himself had not at first believed in her, but that he had seen so much that he had been converted.

At this stage Cesare came to his aid, bearing witness, as he could, that he himself had seen the Prior discredit her when others were already hailing her as a saint, wherefore, if he now was convinced, he must have had very good evidence to convince him.
