Featuring a motif of three or four nested squares of graduated sizes, colors, and hues, this deceptively simple composition is part of Josef Alber's Homage to the Square series. A German émigré, Albers began working on the series in 1949 while teaching at Yale. At the time of his death, he had completed a thousand such works. This lifelong study was devoted to the interaction and interdependence between colors within fixed conditions of proportion and placement. Albers was a major proponent of abstraction, which he considered both the art of the future and the purest and most spiritual form of visual expression.
