Known as the Renaissance, the period immediately following the Middle Ages in Europe saw a great revival of interest in the classical learning and values of ancient Greece and Rome.
The two principal components of Renaissance style are the following: a revival of the classical forms originally developed by the ancient Greeks and Romans, and an intensified concern with secular lifeâinterest in humanism and assertion of the importance of the individual. The Renaissance period in art history corresponds to the beginning of the great Western age of discovery and exploration, when a general desire developed to examine all aspects of nature and the world.
