He had hardly left before Bramante so arranged matters that he could not come back. He ruined his work and his fortunes.
"That affair," writes Michelangelo, "caused me a loss of more than a thousand ducats. When I left Rome there arose a great riot because of the shame put upon the pope, and almost all the blocks of marble which I had on the square of St. Peter's were taken from me, especially the smaller pieces, which made it necessary for me later on to begin the whole work over again."
Nevertheless Julius II was furious at the revolt of his sculptor and sent letter after letter to the Signory of Florence where Michelangelo had betaken himself. The Signory, anxious not to compromise themselves, tried to persuade Michelangelo to take once more the road to Rome, but he would do nothing of the kind. He had tranquilly taken up his work on the cartoon of The Battle, the Twelve Apostles for the cathedral and the Madonna of Bruges, and he stubbornly persisted in his unwillingness to return. He proposed his own terms and pretended to be working on the tomb of Julius II at Florence. When, toward the end of August, 1506, Julius II went to war with Perugia and Bologna and grew more importunate in his demands Michelangelo had the idea of expatriating himself. He thought of going to Turkey, where the Sultan, through the Franciscans, invited him to come to Constantinople and build a bridge at Pera.[25]
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. 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.
