spirit of the age, art became more secular in subject matter, depicting ancient mythology in addition to Christian themes. This genre of art is often referred to as Renaissance Classicism. In the North, the most important Renaissance innovation was the widespread use of oil paints, which allowed for greater colour and intensity. From Gothic to the Renaissance During the late 13th century and early 14th century, much of the painting in Italy was Byzantine in character, notably that of Duccio of Siena and Cimabue of Florence, while Pietro Cavallini in Rome was more Gothic in style. During the 13th century, Italian sculptors began to draw inspiration not only from medieval prototypes, but also from ancient works. In 1290, Giotto began painting in a manner that was less traditional and more based upon observation of nature. His famous cycle at the Scrovegni Chapel, Padua, is seen as the beginnings of a Renaissance style. Other painters of the 14th century were carried the Gothic style to great elaboration and detail. Notable among these painters are Simone Martini and Gentile da Fabriano. In the Netherlands, the technique of painting in oils rather than tempera, led itself to a form of elaboration that was not dependent upon the application of gold leaf and embossing, but upon the minute depiction of the natural world. The art of painting textures with great realism evolved at this time. Dutch painters such as Jan van Eyck and Hugo van der Goes were to have great influence on Late Gothic and Early Renaissance painting. Early Renaissance The ideas of the Renaissance first emerged in the city-state of Florence, Italy. The sculptor Donatello returned to classical techniques such as contrapposto and classical subjects like the unsupported nude—his second sculpture of David was the first free-standing bronze nude created in Europe since the Roman Empire. The sculptor and architect Brunelleschi studied the architectural ideas of ancient Roman buildings for inspiration. Masaccio perfected elements like composition, individual expression, and human form to paint frescoes, especially those in the Brancacci Chapel, of surprising elegance, drama, and emotion. A remarkable number of these major artists worked on different portions of the Florence Cathedral. Brunelleschi's dome for the cathedral was one of the first truly revolutionary architectural innovations since the Gothic flying buttress. Donatello created many of its sculptures. Giotto and Lorenzo Ghiberti also contributed to the cathedral. High Renaissance High Renaissance artists include such
