Art Deco was the style-commentator of many architectural trends in the early decades of the twentieth century. Before it culminated in the architecture of the American skyscraper, Art Deco had become an international style in art, architecture, and design. The Art Deco skyscraper in New York is this style's most ambitious archi- tectural aspiration. The stylistic qualities of Art Deco – in particular, tight decorative surfaces with various forms of modernistic ornament – endowed the skyscraper with a cluster of architectural images which reached back to ancient forms of design as well as forward into the modernistic esthetic. In this book, the Art Deco skyscraper in New York is analyzed against the background of decoration, ornament, symbolism, eclecticism, and modernism in the art and architecture of the twentieth century.
