Michael Angelo now executed a Madonna in bronze, and copied the wonderful frescos of Masaccio in the Brancacci Chapel of Santa Maria del Carmine (usually called the Carmine Chapel), the same which inspired Fra Angelico, Raphael, and Andrea del Sarto. "The importance of these frescos arises from the fact that they hold the same place in the history of art during the fifteenth century as the works of Giotto, in the Arena Chapel at Padua, hold during the fourteenth. Each series forms an epoch in painting, from which may be dated one of those great and sudden onward steps which have in various ages and countries marked the development of art. The history of Italian painting is divided into three distinct and well-defined periods, by the Arena and Brancacci Chapels, and the frescos of Michael Angelo and Raphael in the Vatican." While Michael Angelo was copying these paintings of Masaccio, he took no holidays, and gave the hours of night to his labors. Ambition made work a delight. He studied anatomy like a devotee. Dead bodies were conveyed from the hospital to a cell in the convent of Santo Spirito, the artist rewarding the prior by a crucifix almost as large as life, which he carved from wood. The youth could but know his superiority to others, and was not always wise enough to conceal his contempt for mediocrity, or for the young men who played at life. One of his fellow-students, Torrigiani, grew so angry at him, probably from some slighting remark, that he struck him with his fist, disfiguring his face for life. Michael Angelo is said to have merely replied to this brutal assault, "You will be remembered only as the man who broke my nose." Torrigiani was at once banished, and died miserably in the Spanish Inquisition. In April, 1492, Lorenzo the Magnificent died, in the very prime of his life. Michael Angelo was so overcome that for a long time he was unable to collect his thoughts for work. The self-reliant young man, cold outwardly, had a warm and generous heart. He went home to the Buonarotti mansion, opened a studio, purchased a piece of marble and made a Hercules four feet in height. It stood for many years in the Strozzi Palace in Florence, was sold to France, and is now lost. Piero de' Medici succeeded to his father Lorenzo, who is said to have remarked that "he had three sons: the first good, the second clever, the third a fool. The good one was Giuliano, thirteen years old at the death of his father; the clever one was Giovanni, seventeen years old, but a cardinal already by favor of the pope, whose son had married a daughter of Lorenzo's; and the fool was Piero."
