Mannerism – Instead of using nature as their teacher, Mannerist artists took art itself as their inspiration. In this regard they were able to call upon the earlier works of such greats as Michelangelo and Leonardo. (Michelngelo himself in his later years was also a Mannerist)
Unlike Renaissance artists who studied nature to find their style, the Mannerists looked first for a style and then found a manner in which to paint it – hence the term mannerism.
Mannerism matured after 1520 (the year Raphael died), when Early Renaissance and the High Renaissance artists developed their characteristic styles from the observation of nature and the formulation of a pictorial science.
Other notable artists of this period include: Correggio and Andrea Del Sarto.
Mannerism was displaced with the arrival of Baroque.
