One of the preeminent artists of his generation, Mark Rothko is closely identified with the New York school, a circle of painters that emerged during the 1940s as a new collective voice in American art. During a career that spanned five decades, he created a new and impassioned form of abstract painting.

Rothko's work is characterized by rigorous attention to formal elements such as color, shape, balance, depth, composition, and scale; yet, he refused to consider his paintings solely in these terms. He explained: "It is a widely accepted notion among painters that it does not matter what one paints as long as it is well painted. This is the essence of academicism. There is no such thing as good painting about nothing."

By 1949 Rothko had introduced a compositional format that he would continue to develop throughout his career. Composed of several vertically aligned rectangular forms set within a colored field, Rothko's "image" lent itself to a remarkable diversity of appearances.

In these works, large scale, open structure, and thin layers of color combine to convey the impression of a shallow pictorial space. Color, for which Rothko's work is perhaps most celebrated, here attains an unprecedented luminosity.
