Nevelson's Sky Cathedral, created in 1958, is her masterpiece. This piece of art best represents her because it combines the qualities she uses in most of her art. It is made from recycled wood, it consists of boxes filled with more scrap material, and it is painted black. This piece of art uses material such as "moldings, dowels, spindles, chair parts, architecture ornaments, and scroll-sawed fragments". ( Sky Cathedral is now located in the Albright-Knox Art Gallery, Buffalo. Created from wood, it is 115x135x20 inches. ( This piece of art, meant to be against a wall and seen from the front, is linear because of the boxes that make it up. Nevelson created shadow with her art by using boxes and other three-dimensional forms. The boxes also create space, as the objects inside recede. This piece of art can fit into the movements of Cubism, Surrealism, and Abstract Expressionism. It is similar to Abstract Expressionism because of the size. It is similar to Cubism because of the lines, curves, and overlapping pieces. It is similar to Surrealism because of the "curious bric-à-brac". ( Sky Cathedral is Louise Nevelson's masterpiece.
