Donald Judd, Untitled 1989 represents the apex of Donald Judd’s career-long involvement with establishing space and color as the foremost elements in art. The creation of rectilinear objects that confronted the viewer with their obdurate material presence was part of the visual vocabulary of so-called Minimalist artists, among them Robert Morris and Dan Flavin. But, only with Flavin does Judd share the extraordinarily compelling visual opulence that catalyzed these artists’ concern with the visual activation of space. Writing “there is no neutral space, since space is made,” with Untitled, Judd insisted that his objects existed as self-evident participants with no relation to anything beyond their factual presence: material and color are the work’s only constituent elements.
