In March, 1505, Michelangelo was called to Rome by Pope Julius II. Then began the heroic period of his life and the "tragedy" of the monument of Julius II which was not to end until forty years later. The pope and the artist, both of them proud and violent, were well fitted to work together--so long as their ideas did not conflict. Their brains seethed with tremendous ideas. The first years of their friendship were a feverish delirium of plans. Julius II was on fire with enthusiasm for the plan for his tomb which Michelangelo submitted to him. It was to be a mountain of architecture with more than forty statues, some of them of colossal size, and with many bronze reliefs. "Michelangelo's design pleased the pope so much," says Condivi, "that he sent him at once to Carrara (April, 1505) with an order to cut as much marble as he needed.... Michelangelo stayed more than eight months in the mountains with two servants and a horse." He was the victim of superhuman exaltation and in his enthusiasm dreamt of carving a whole mountain. In December, 1505, he returned to Rome, where the blocks of marble which he had chosen had already begun to arrive from Carrara. They were unloaded at La Ripa and then transported to the Piazza di San Pietro behind S. Caterina, where Michelangelo lived. "The mass of the stones was so great that they aroused the wonder and joy of the pope." Michelangelo set to work. "The pope in his impatience came constantly to see him and conferred with him over the monument and other works, with as much familiarity as if he had been his brother. In order that he might visit him the more easily he had a drawbridge thrown across from the gallery of the Vatican to Michelangelo's house which gave him a secret passage." But this favour did not last. The character of Julius II was as passionate and as changeable as that of Michelangelo. His mind, always in a ferment, took up in rapid succession and ever with the same eagerness the most varied projects. Another idea drove the plan for the tomb from his mind. In order that he might gain immortal glory by one gigantic work he decided to reconstruct St. Peter's. He was encouraged in this by enemies of Michelangelo, who himself writes in 1542:[23] "All the difficulties which arose between the pope and myself were the work of Bramante and of Raphael. It was their jealousy that kept him from having his tomb made while he was still alive. They tried to ruin me. Raphael had good reason for doing this, since all that he knew of art he learnt from me." It is not easy to say how far Raphael was carried along by the party of Bramante, who was his friend and fellow-countryman, but there is no doubt that Bramante was chiefly responsible for the check to Michelangelo's great undertaking and that he profited by his absence in Carrara to destroy his influence over the pope.
