Italian sculptor, part of a family of artists, the son of the sculptor Simone Mosca. He also worked in Orvieto, and he may have completed his father's unfinished commissions. For the cathedralGLOSSARYThe principal church of a province or diocese, where the throne of the bishop is placed. For reasons lost to time and tradition, a cathedral always faces west - toward the setting sun. The altar is placed at the east end. The main body, or nave, of the cathedral is usually divided into one main and two side aisles. These lead up to the north and south transepts, or arms of the cross, the shape in which a cathedral is usually formed. there he executed a nude statue of St Sebastian and figures of St Peter and St Paul. He also executed statues for Pisa Cathedral (a Virgin and Child and Angel in the chapelGLOSSARYa small separate place for worship, either part of a large church or a separate building. of the AnnunciationGLOSSARYthe term for the event described in the Gospel according to St. Luke, when the Angel Gabriel brings the Virgin Mary the news that she is to bear her son, Jesus Christ. The Annunciation was among the most widespread pictorial subjects of European art during the Middle Ages and the Renaissance.) and in 1577 travelled to Parma, where he was employed briefly by the Farnese as court sculptor. A marbleGLOSSARYloosely applied to any hard limestone that can be sawn into thin slabs and will take a good polish so that it is suitable for decorative work; more strictly, it refers to metamorphosed limestones whose structure has been recrystallized by heat or pressure. Marbles are widely disseminated and occur in a great variety of colours and patterns, but certain types have been particularly prized by sculptors. The most famous of Greek white marbles in the ancient world was the close-grained Pentelic, which was quarried at Mount Pentelicon in Attica. The Elgin Marbles are carved in Pentelic. Widely used also were the somewhat coarser-grained translucent white marbles from the Aegean islands of Paros and Naxos. Parian marble was used for the celebrated Mausoleum at Halicarnassus. The pure white Carrara marble, quarried at Massa, Carrara, and Pietra Santa in Tuscany from the 3rd century BC, is the most famous of all sculptors' stones. It was used for the Apollo Belvedere, and was much favoured in the Renaissance, particularly by Michelangelo, who often visited the quarries to select material for his work. Neoclassical sculptors also favoured Carrara marble because of its ability to take a smooth, sleek surface, but it can look rather 'dead' compared with some of the finest Greek marbles. reliefGLOSSARYA sculptural work in which all or part projects from the flat surface. There are three basic forms: low relief (bas-relief, basso rilievo), in which figures project less than half their depth from the background; medium relief (mezzo-rilievo), in which figures are seen half round; and high relief (alto rilievo), in which figures are almost detached from their background. of Diana and Acteon (Florence, Bargello) and a free-standing group of Atalanta and Meleager (Kansas City, Nelson-Atkins Museum of Art) reflect Francesco's indebtedness to mid-16th-century MannerismGLOSSARYA movement in Italian art from about 1520 to 1600. Developing out of the Renaissance, Mannerism rejected Renaissance balance and harmony in favor of emotional intensity and ambiguity. In Mannerist painting, this was expressed mainly through severe distortions of perspective and scale; complex and crowded compositions; strong, sometimes harsh or discordant colors; and elongated figures in exaggerated poses. In architecture, there was a playful exaggeration of Renaissance forms (largely in scale and proportion) and the greater use of bizarre decoration. Mannerism gave way to the Baroque. Leading Mannerists include Pontormo, Bronzino, Parmigianino, El Greco and Tintoretto..
