Cappelle Medicee Florence The Medici Chapels form part of the monumental complex of San Lorenzo. The church of San Lorenzo was the official church of the Medici, becoming their mausoleum. The project for a family tomb was conceived in 1520 when Michelangelo began work on the New Sacristy. It was above all Cardinal Giulio de' Medici, future Pope Clement VII who wished to erect a mausoleum for certain members of his family, Lorenzo the Magnificent and his brother Giuliano, and Lorenzo, Duke of Urbino and Giuliano, Duke of Nemours. Michelangelo worked on the sculptures of the sarcophagi until 1533, but the only ones actually completed were the statues of the Dukes Lorenzo and Giuliano, the allegories of Dawn and Dusk, Night and Day and the group of Madonna and Child placed above the sarcophagus of the two "magnifici" and flanked by Saints Cosmas and Damian. As a' result of the complex history of the chapel and its elaborate symbolism, many interpretations have been made of its sculptures.turkeyarena.com The poses of the two principal figures represent the Active and Contemplative lives while the famous statues on the sarcophagi probably refer to the conditions and phases of human life. The tombs also refer to the liberation of the soul after death, a philosophical concept closely linked with Michelangelo's own spirituality.
