Why did Clement Greenberg support Jackson Pollock’s paintings?

Clement Greenberg was an early and influential champion of Jackson Pollock, supporting his work primarily because it aligned with Greenberg’s formalist aesthetic theories.12

As a critic for The Nation in the 1940s, Greenberg advocated for Abstract Expressionism and viewed the evolution of 20th-century art as a progression toward pure abstraction. He praised art that focused on the intrinsic qualities of its medium—such as the flatness of the canvas and the application of paint—rather than on descriptive content or narrative.2

Greenberg saw Pollock’s gestural, non-representational canvases as a significant step in this development. His support was rooted in his belief that such work created a pure, immediate visual sensation. Over time, Greenberg’s critical perspective became increasingly focused on these formal elements, and he used his influence to promote Pollock as a groundbreaking figure who embodied the direction of modern art.21
