took fantastic zoomorphic forms; surviving examples are mostly in brass. Many wax impressions from impressive seals survive on charters and documents, although Romanesque coins are generally not of great aesthetic interest. The Cloisters Cross is an unusually large ivory crucifix, with complex carving including many figures of prophets and others, which has been attributed to one of the relatively few artists whose name is known, Master Hugo, who also illuminated manuscripts. Like many pieces it was originally partly coloured. The Lewis chessmen are well-preserved examples of small ivories, of which many pieces or fragments remain from croziers, plaques, pectoral crosses and similar objects. Gothic The Gothic period is essentially defined by Gothic architecture, and does not entirely fit with the development of style in sculpture in either its start or finish. The facades of large churches, especially around doors, continued to have large typanums, but also rows of sculpted figures spreading around them. The statues on the Western (Royal) Portal at Chartres Cathedral (c. 1145) show an elegant but exaggerated columnar elongation, but those on the south transept portal, from 1215 to 1220, show a more naturalistic style and increasing detachment from the wall behind, and some awareness of the classical tradition. These trends were continued in the west portal at Reims Cathedral of a few years later, where the figures are almost in the round, as became usual as Gothic spread across Europe. In Italy Nicola Pisano (1258–1278) and his son Giovanni developed a style that is often called Proto-Renaissance, with unmistakable influence from Roman sarcophagi and sophisticated and crowded compositions, including a sympathetic handling of nudity, in relief panels on their pulpit of Siena Cathedral (1265–68), the Fontana Maggiore in Perugia, and Giovanni's pulpit in Pistoia of 1301. Another revival of classical style is seen in the International Gothic work of Claus Sluter and his followers in Burgundy and Flanders around 1400. Late Gothic sculpture continued in the North, with a fashion for very large wooden sculpted altarpieces with increasingly virtuoso carving and large numbers agitated expressive figures; most surviving examples are in Germany, after much iconoclasm elsewhere. Tilman Riemenschneider, Veit Stoss and others continued the style well into the 16th century, gradually absorbing Italian Renaissance influences. Life-size tomb effigies in stone or alabaster became popular for the wealthy, and grand multi-level tombs evolved, with the Scaliger Tombs of Verona so large they had to be moved outside
