Jackson Pollock was an innovative artist who brought about a revolution in 20th-century art. He developed unique techniques such as "dripping," "splashing," and "pouring" paint directly onto large canvases, which allowed for expressions entirely different from traditional painting. Pollock is known for pioneering action painting, where the process and act of creation are emphasized over the final product, introducing a new concept of "action" in art. His works are characterized by an "all-over" structure, lacking a central focus or direction, making the entire canvas uniformly significant. Pollock's influence established a new American art movement, challenging the European dominance in the art world. His lines did not define shapes but created a new concept of drawing with lines. Although initially critiqued, Pollock's innovative approach was highly regarded by art critics like Clement Greenberg and significantly influenced modern art, fundamentally changing its direction in the 20th century.
