In November, 1506, when the pope had taken Bologna, he sent for Michael Angelo to come to him there. Michael Angelo had not yet seen the pope since he left Rome in anger. When he reached Bologna he went first to San Petronio to hear mass. A servant of the pope recognized him and led him to his Holiness. Julius was at table, but ordered that Michael Angelo should come in, and said to him, "You have waited thus long, it seems, till we should ourselves come to seek you." Michael Angelo kneeled down and begged his pardon, but added that he had remained away because he had been offended. The pope looked at him doubtfully, when one of the priests, fearing what would happen, advised the pope not to judge an ignorant artist as he would another man. Then the pope turned upon him in great anger, and declaring that he himself was ignorant and miserable, ordered him out of his sight. The poor ecclesiastic was so terrified that the attendants were obliged to carry him out, and then the pope spoke graciously to the sculptor, and commanded him not to leave Bologna without his permission. The pope soon gave him an order for a colossal statue in bronze to be erected in Bologna. The first cast of this statue failed, and the work was not ready to be put in its place until February, 1508. This being done, Michael Angelo returned to Florence, where he had much to do; but Julius soon sent for him to go to Rome, and insisted that he should paint the roof of the Sistine Chapel, which occupied him a long time. In 1513 Julius II. died, and Michael Angelo resumed his work upon his mausoleum. The pope had mentioned it in his will, and his heirs wished it to be completed. At this time he probably worked upon the statue of Moses and upon the two chained youths. He devoted himself to the mausoleum during three years. Leo X., who was now pope, demanded the services of Michael Angelo to erect a facade to the Church of San Lorenzo in Florence. The artist objected to this great work, and declared that he was bound to complete the tomb for which he had already received money. But Leo insisted upon his going to Florence. He had much trouble to get his marble from the quarries--the men were ill there. He was ill himself, and he passed a year of great anxiety and trouble, when there came word from Rome that the work must be given up; the building was postponed, and no payment was made to Michael Angelo! He was much disheartened, but returned to his work on the mausoleum.
