Mannerism was an artistic movement that emerged in the late Renaissance, roughly from the 1520s to the 1600s, characterized by exaggerated proportions, unconventional poses, and a complex composition style. It deviated from the harmony and balance of High Renaissance art, embracing tension, emotion, and a sense of artificiality. This movement reflects the changing social and political landscape of the time, marked by religious conflicts and the rise of individualism in art.
