Which artist is known for a style that changed more than any other?

Pablo Picasso is recognized for a style that underwent substantial transformations throughout his career, reflecting his innovative approach to art. He co-founded the Cubist movement, which revolutionized the representation of form and perspective, breaking away from traditional artistic conventions. His work can be characterized by distinct phases, including the Blue Period, the Rose Period, and his later exploration of collage and mixed media.

This constant evolution is one of the reasons Picasso is often considered to have the most varied artistic styles compared to other artists. While Vincent Van Gogh, Claude Monet, and Frida Kahlo all produced significant and stylistically unique works, their artistic changes do not match the breadth and depth of transformation seen throughout Picasso's lengthy career. Each of these artists has a distinct style that, while influential, remained more consistent in their overall thematic and formal approaches.
