During the 1940s, there was a creative zeitgeist between two proponents of Expressionist painting, Irving Kriesberg and Jackson Pollock. Pollock's circular painting, aptly titled Circle (c. 1938-41), and Kriesberg's series of 'wheel' paintings (c. 1946-1948) share specific affinities that speak to each artist's interests connecting Expressionism with non-European modes of art.
