High Quality Content by WIKIPEDIA articles! Mannerism is a period of European art that emerged from the later years of the Italian High Renaissance around 1520. It lasted until about 1580 in Italy, when a more Baroque style began to replace it, but Northern Mannerism continued into the early 17th century throughout much of Europe.Stylistically, Mannerism encompasses a variety of approaches influenced by, and reacting to, the harmonious ideals and restrained naturalism associated with artists such as Leonardo da Vinci, Raphael, and early Michelangelo. Mannerism is notable for its intellectual sophistication as well as its artificial (as opposed to naturalistic) qualities.
