Book excerpt: Influenced by a revival of interest in Greco-Roman ideals and sponsored by a newly prosperous merchant class, fifteenth-century artists produced works of astonishingly innovative content and technique. The International Gothic style of painting, still popular at the beginning of the century, was giving way to the influence of Early Netherlandish Flemish masters such as Jan van Eyck, who emphasized narrative and the complex use of light for symbolic meaning. Patrons favored paintings in oil and on wooden panels for works ranging from large, hinged altarpieces to small, increasingly lifelike portraits. In the Italian city-states of Florence, Venice, and Mantua, artists and architects alike perfected existing techniques and developed new ones. The painter Masaccio mastered linear perspective; the sculptor Donatello produced anatomically correct but idealized figures such as his bronze nude of David; and the brilliant architect and engineer Brunelleschi integrated Gothic and Renaissance elements to build the self-supporting dome of the Florence Cathedral. This beautifully illustrated guide analyzes the most important people, places, and concepts of this early Renaissance period, whose explosion of creativity was to spread throughout Europe in the sixteenth century.
