As a rectangular plane to be viewed from the front, Sky Cathedral has the pictorial quality of a painting—perhaps one of the preceding decade's Abstract Expressionist canvases, which share its mural scale. But this sculpture in relief commands a layered depth. Its intricacy lies in both the method of its construction—it is made of shallow open boxes fitted together in a jigsawlike stack—and those boxes' contents, the salvaged wood bits and pieces with which Nevelson filled many of her works. These include moldings, dowels, spindles, chair parts, architectural ornaments, and scroll-sawed fragments. Nevelson makes this material into a high wall variegated by a play of flatness and recession, straight lines and curves, overlaps and vacancies, that has been likened to the faceting of Cubism and has an absorbing visual complexity.
A Surrealist artist might have shared Nevelson's relish for curious bric-à-brac, but might also have arranged such a collection in jarring and disorienting juxtapositions. Nevelson, by contrast, paints every object and box the same dully glowing black, unifying them visually while also obscuring their original identities. The social archaeology suggested by the objects' individual histories and functions, then, is muted but not erased; it is as if we were looking at the wall of a library, in which all of the books had been translated into another language.
