Zigzag, sometimes known as stepping, is a type of architecture intended to make height more prominent. It is a design primarily associated with skyscrapers. A zigzag building has a wide base, but narrows gradually in steps as it works its way upward. A clear example is the Chrysler Building in New York City. The style is partly influenced by the pyramids of Ancient Egypt.
Classic Moderne is an architectural design that is both symmetrical and graceful. These buildings were typically serene and dignified. They were normally structured horizontally, with some zigzag elements to provide a balance between traditional and avant garde styles. The buildings were often decorated with a mixture of artwork, such as painted murals and carved sculptures. These designs remained prominent after the Roaring Twenties; many of President Roosevelt's publicly funded buildings adopted the Classic Moderne style.
Metal was a regular fixture within Art Deco designs, representing the prowess and strength of the American industrial industry. The metals used were sleek and lightweight; stainless steel, bronze and aluminum were all common. The intention was to add aesthetic value; metal was used in a range of artwork and accessories such as sculptures, radiator covers, light stanchions, doors and cornices. Metal sculptures were often shaped like plants or fashioned using traditional Native American symbolism.
Art Deco designs would often display nationalistic and patriotic symbolism. This was intended to instill a sense of national pride. The 1925 Paris Art Deco Exposition featured artwork from all around the world, and many designs contained national imagery from the country of origin. In the United States, the imagery was used on both public and private buildings. A good example is the two eagles perched on top of the Eastern Airlines building, part of the Rockefeller Center.
