In the end he had to give in, and in the latter part of November, 1506, he went, much against his will, to Bologna, where Julius II had just entered the town as a conqueror. There took place that famous interview when the pope, angry and scolding, divided between the desire of punishing the rebel and the fear of losing the artist whom he valued, poured out his wrath on an unlucky bishop who was present, and forgave Michelangelo.

Unfortunately, Michelangelo in order to make his peace with the pope, had to submit to his caprices and to that all-powerful will which had now turned in a new direction. It was no longer a question of the tomb, but of a colossal bronze statue which Julius wished to have raised to himself in Bologna.

In vain Michelangelo protested that he understood nothing about the casting of bronze. He had two assistants, Lopo and Lodovico, come from Florence, and a foundryman, Bernadino d'Antonio dal Ponte. But he could never get along with any assistant.[{34}] He fell out with Lodovico and Lopo, who stole from him; then the foundryman turned out to be incapable and in June, 1507, the casting failed.

"The figure came out only as far down as the waist. Everything had to be done over again."

Fifteen months were spent in the midst of all kinds of troubles and mortifications. Michelangelo was busy with his work until February, 1508. He nearly ruined his health over it, and he wrote to his brother that he would never be in condition to make such an effort again during his life. For so great a struggle, the result was miserable. The statue of Julius II, raised on February 21, 1508, in front of the façade of S. Petronio remained there only four years.[26] In December, 1511, it was destroyed on the return of the Bentivogli, and Alphonso d'Este had his bombardier Quirino cast a cannon from its fragments.

Michelangelo returned to Rome and Julius II laid upon him another task not less unexpected and not less hazardous. He ordered the sculptor, who never painted except with reluctance and who knew nothing of the technique of fresco, to paint the ceiling of the Sistine Chapel. He had already talked with him about it before the rupture in 1506 and the disinclination[{35}] of Michelangelo for this work had something to do with his flight to Florence. This may be inferred from the letter of a friend of Michelangelo written in May, 1506, which shows that Bramante, satisfied by the withdrawal of his rival, justified him for refusing the burden of this heavy undertaking.

"Last Saturday evening," writes Pietro Rosselli, "when the pope was supping, he called Bramante and said, 'San Gallo is going tomorrow to Florence and he will bring back Michelangelo.' Bramante answered, 'Holy Father, Michelangelo will do nothing of the kind. I have talked a great deal with him and he has often said to me that he would not undertake the chapel which you wished to entrust to him. He asks to be allowed with your permission to devote himself entirely to sculpture, for he wants to have nothing to do with painting.' He added, 'Holy Father, I do not think he has the courage to undertake the work, for he has had little experience in the painting of figures, and these must be painted on the ceiling and foreshortened, which is very different from painting on the ground.' The pope answered, 'If he does not come he will be treating me badly, and for that reason I think he will return.' I threw myself into the conversation and there in the pope's presence replied properly to that fellow[{36}] and spoke for you as you would surely have spoken for me. Bramante remained silent, realising that he had made a mistake in saying what he had. I went on in these words: 'Holy Father, that man has never exchanged a word with Michelangelo, and if what he says is true you can cut my head off. He has never talked with him, and I am sure that Michelangelo will come back if Your Holiness wishes it.'" When Michelangelo returned Bramante changed his tactics. As Michelangelo's friends had imprudently asserted that he could accomplish this task for which, as Bramante knew better than any one else, he was entirely unprepared, Bramante pretended to believe this and forced his rival into a position where he had to accept the commission. A failure would have been particularly serious to Michelangelo just then since in that same year, 1508, Raphael began his incomparable painting of the Stanze and Michelangelo had either to surpass him or be entirely eclipsed. This at least is what Condivi asserts.

Bramante and his other rivals suggested to the pope to make Michelangelo paint the ceiling of the chapel of Pope Sixtus IV by persuading him that he would do marvels there. They did him this service maliciously to distract the pope from any plan for sculpture and because they thought that Michelangelo would either refuse the commission[{37}] and quarrel with the pope or that he would accept it and be less successful than Raphael, for they considered that Michelangelo's talent was for sculpture, which indeed was true. Michelangelo, who until then had not worked in colours and who knew how difficult it is to paint a ceiling, tried in every way to extricate himself. He proposed Raphael in his place and gave as an excuse that this was not his art and that he could not succeed in it, and went so far in his attempts at refusal that the pope began to grow angry and showed such obstinate determination that Michelangelo decided to undertake the work.

The tremendous task began on May 10, 1508. The first plan was simply to represent the figures of the twelve apostles in the lunettes and to fill the rest of the space with an ornamental decoration. Bramante raised a scaffolding in the chapel and several painters who had had practical experience in fresco painting were brought from Florence. We have already said that Michelangelo could only work alone. He began by declaring that Bramante's scaffolding was of no use and replaced it with one of his own invention. As for the Florentine painters who Francesco Granacci had recruited for him, Giuliano Bugiardini, Jacopo di Sandro, the elder Indaco, and Agnolo di Donnino, he took a dislike[{38}] like to them and sent them away. He remained alone, shut up in the chapel with a few workmen, like Giovanni Michi, and far from allowing the great difficulty of the undertaking to dampen his courage he enlarged his plan and decided to paint not only the ceiling, but the walls of the chapel down to the old frescoes.
