Symbolism is a 19^th-century movement in which art became infused with a spooky mysticism. It was a continuation of the Romantic tradition, which included such artists as Caspar David Friedrich and John Henry Fuseli. Anticipating Freud and Jung, the Symbolists mined mythology and dream imagery for a visual language of the soul. More a philosophy than an actual style of art, they influenced the contemporary Art Nouveau movement and Les Nabis. The leading Symbolists included Gustave Moreau, Odilon Redon, and Pierre Puvis de Chavannes. The movement was also a major influence on some of the Expressionists, especially through the work of Edvard Munch and Franz von Stuck.
