Who is works reflected the high point of mannerism?

The works of Michelangelo Buonarroti are often considered to reflect the high point of Mannerism. His later sculptures, such as "The Last Judgment" in the Sistine Chapel, and his intricate architectural designs demonstrate the elongated forms, complex poses, and emotional intensity characteristic of the style. Additionally, artists like Parmigianino and El Greco also exemplify Mannerist qualities through their unique approaches to figures and composition.
