In his exploration of formal issues, Stella habitually worked in series, developing increasingly complicated variations on selected themes. In contrast to the monochrome Black Paintings, the Protractor series, to which Harran II belongs, deploys a vivid palette and composition consisting of rectangular shapes superimposed on curving and circular forms. As in The Marriage of Reason and Squalor, Harran II's stripes emphasize the flatness of the composition, reminding the viewer that a painting is merely canvas covered with paint. This concept is reinforced by the use of the shaped canvas, which, challenging the conventional rectangular format, further denies the painting's status as illusionistic window and enhances its "object-like" quality. Harran II - whose title comes from the name of an ancient city in Asia Minor - invites parallels with sculpture as well as architecture. Measuring a massive 10 x 20 feet, the work is architectural in scale, while its composition was based on the semicircular drafting tool for measuring and constructing angles.
