Michelangelo
Michelangelo returned to Florence in 1499. The republic was changing after the fall of its leader, anti-Renaissance priest Girolamo Savonarola, who was executed in 1498, and the rise of the "gonfaloniere" Piero Soderini. Michelangelo was asked by the consuls of the Guild of Wool to complete an unfinished project begun 40 years earlier by Agostino di Duccio: a colossal statue of Carrara marble portraying David as a symbol of Florentine freedom to be placed on the gable of Florence Cathedral. Michelangelo responded by completing his most famous work, the statue of David, in 1504. The masterwork definitively established his prominence as a sculptor of extraordinary technical skill and strength of symbolic imagination. A team of consultants, including Botticelli and Leonardo da Vinci, was called together to decide upon its placement, ultimately the Piazza della Signoria, in front of the Palazzo Vecchio. It now stands in the Academia while a replica occupies its place in the square.
Michelangelo
In November 1497, the French ambassador to the Holy See, Cardinal Jean de Bilhères-Lagraulas, commissioned him to carve a "Pietà", a sculpture showing the Virgin Mary grieving over the body of Jesus. The subject, which is not part of the Biblical narrative of the Crucifixion, was common in religious sculpture of Medieval Northern Europe and would have been very familiar to the Cardinal. The contract was agreed upon in August of the following year. Michelangelo was 24 at the time of its completion. It was soon to be regarded as one of the world's great masterpieces of sculpture, "a revelation of all the potentialities and force of the art of sculpture". Contemporary opinion was summarised by Vasari: "It is certainly a miracle that a formless block of stone could ever have been reduced to a perfection that nature is scarcely able to create in the flesh." It is now located in St Peter's Basilica.
