Meandering, looping, flamboyant lines characterize our understanding of the style known as Art Nouveau. In "Imperishable Beauty: Art Nouveau Jewelry" that understanding is explored through the jewels of an American private collection. Art Nouveau emerged in France and Belgium to become an international style with local variations. Yvonne Markowitz presents an intelligent and thorough overview of the movement, locating its common themes in the art of the Pre-Raphaelites, the theory of John Ruskin, the Symbolist movement and the arts in Japan. She discusses the similarities and differences in style and concludes with a section on materials and techniques.Part 2 looks at the iconography of Art Nouveau jewelry and how a series of motifs was repeated in the work of many jewelers. These symbols were designed to be read and understood by those with artistic taste and sensibility. Elyse Karlin interprets such works as the sexually charged and fantastically curved carnation by Rene Lalique. The catalogue consists of nearly ninety ornaments by jewelers as renowned as Rene Lalique, Philippe Wolfers and Henri Vever. Including a biography of all the artists represented in the collection and using comparative material in the form of posters, textiles and paintings, "Imperishable Beauty" offers a unique angle on the Art Nouveau movement.
