The Tree of Life wall hanging, also known as L'Arbre de Vie, Stoclet Frieze in French, was painted in 1909 by Art Nouveau artist Gustav Klimt. This pattern was originally a study for a series of mosaics commissioned for the Palais Stoclet in Brussels. Done in rich, warm colours, this piece presents the traditional Tree of Life bearing fruit and birds, but in a flowing, spiraling nouveau style. Art Nouveau Design.
