Gustav Klimt's 'Golden Phase' produced some of the most recognizable works of Art Nouveau, most notably 'The Kiss' (1907–1908). During this period, Klimt used actual gold leaf in his paintings, a technique inspired by the Byzantine mosaics he saw in Ravenna, Italy. The use of gold elevates his subjects to a divine, iconic status while flattening the perspective, creating a shimmering, ornamental effect. 'The Kiss' depicts a couple encased in elaborate robes, merging into a single golden mass. This period reflected the decadence and opulence of 'Fin de Siècle' Vienna. Klimt was a founding member of the Vienna Secession, a movement that sought to break away from traditional academic art and embrace a more experimental, decorative style that integrated art into daily life.
