Art Nouveau is an international style of art, architecture and applied arts, most notably decorative arts, that began in Europe in the 1890s and early twentieth century. Signature characteristics include an ornamental vocabulary based on natural growing forms with motifs influenced by Japan. The style is open, curvilinear, asymmetrical and organic. It's often identified by its whiplash curve—a line that is long and slightly curved ending abruptly in a whip-like sharp curve.
The name comes from Siegfried Bing’s gallery in Paris called Maison de l’Art Nouveau. Some key names include (but are not limited to): Hector Guimard, Victor Horta, Henri Van de Velde, Charles Rennie Mackintosh and Charles Rohlfs. Above: Art Nouveau vase and candélabre. Interior by Darren Henault
