While Ellsworth Kelly is perhaps best known for his abstract paintings—canvases with sharply delineated areas of bold, flat color laid out in pure geometric shapes—the sculptures he has made throughout his career explore many of the same issues regarding form and space. The two eighteen-foot, gently curving bronze arcs of Double Curve are insistently two-dimensional (viewed from the side, they almost disappear). Like the flat shapes in his paintings, they depend on their precisely controlled relationship to each other and to the surrounding area for their impact and surprising complexity. Viewing the surfaces themselves—rich brown in the morning light, stark black silhouettes in the midday sun—the arcs seem to be bending toward one another; viewing the shapes between or around the arcs, a new vibrancy of space, in rhythm with the surrounding landscape, emerges.
