Modernism – Art-Deco. This style found its way, in the 1920s and 1930s, into almost all areas of modern life: architecture, household objects, sculpture, graphics, furniture and jewelry. The geometric Art-Deco patterns are based on straight, curved, circular, triangular, diagonal and zigzag lines. The Art Deco style in Jerusalem was prevalent mainly in decorative ironwork, such as on gates, doors, window grilles, railings and lamps. Some of the Art-Deco design motifs in Arab houses are different from those of the same period, in Jewish houses. Many fine examples of Art-Deco were in gates and window grilles in affluent Arab neighborhoods, such as Talbieh, Katamon and Baq’a. Unfortunately, some of the ironwork illustrated in this chapter, was removed, since the end of the 20th century. Many of the Art-Deco motifs which appear in this chapter, are also included in the fourth volume of this Guide “Modern 20th Century Design Identities”.
