He protected Michelangelo against the importunities of those who came to beg for works of art, and he reprimanded him paternally for accepting these orders. "When anyone asks you for a painting," he said, "you should fasten a brush to your foot, make four strokes and say, 'The picture is done.'" He promised also to arrange Michelangelo's difficulties with the heirs of Julius II. On April 29, 1532, by his mediation a fourth contract was agreed upon between the representative of the heir to Julius II, the Duke of Urbino, Francesco Maria della Rovere and Michelangelo. Michelangelo promised to make a new model of the tomb, to deliver the six statues already begun and still unfinished, as well as everything else that was ready; to complete it in the course of three years at S. Pietro in Vinculi and to pay all the expenses as well as two thousand ducats in compensation for the sums which he had already received. The pope gave him permission to come for two months every year to Rome for this work. Michelangelo was agreeing to the ruin of the greatest undertaking of his life and he had besides to pay so much that he was forced to sell houses and goods. Like the plans for Julius II, the plans for the Medici collapsed. Clement VII died on September 28, 1538. Michelangelo was at that time away from Florence and he never went back there. Duke Alessandro de' Medici hated him, and only his fear of the pope prevented the tyrant from assassinating him. Michelangelo therefore left Florence (where his brother Buonarroto died in January, 1534) just after he had lost his father, Lodovico, in June of that same year. Nothing bound him any longer to his own country, and he was never to see it again. [Illustration: DECORATIVE FIGURE Ceiling of the Sistine Chapel (1508-1512).]
