With classical restraint, Robert Mangold translates the most basic of formal elements—shape, line, and color—into paintings, prints, and drawings whose simplicity of form expresses complex ideas. He renders the surface of each canvas with subtle color modulations and sinewy, hand-drawn graphite lines. While his focus on formal considerations may seem paramount, he also delights in thwarting those considerations—setting up problems for the viewer. Over the course of years and in multiple series of shaped canvases that explore variations on rings, columns, trapezoids, arches, and crosses, he has also provoked viewers to consider the idea of paintings without centers.
