Symbolism, a late 19th-century movement of Post-Impressionist painting, flourished throughout Europe between 1886 and 1900 in almost every area of the arts. Initially emerging in literature, including poetry, philosophy and theatre, it then spread to music and the visual arts. Symbolist art had strong connections with the Pre-Raphaelites and with Romanticism, as well as the Aestheticism movement. Like all these movements, Symbolism was in large part a reaction against naturalism and realism, and became closely associated with mythological painting of all kinds. Where realists and naturalists sought to capture optical reality in all its objective grittiness, and thus focused on the ordinary rather than the ideal, Symbolists sought a deeper reality from within their imagination, their dreams, and their unconscious. Famous symbolist painters included Gustave Moreau (1826-98), Arnold Bocklin (1827-1901), Ferdinand Hodler (1853-1918), Max Klinger (1857-1920), Paul Gauguin (1848-1903), James Ensor (1860-1949), Edvard Munch (1863-1944), Odilon Redon (1840-1916), and Puvis de Chavannes. Although shortlived, the movement had a strong influence on German art of the 19th century, and a big impact on 20th century European artists, particularly those involved in Les Nabis and Art Nouveau, and also the Expressionism and Surrealism movements. It also influenced artists like Whistler, Giorgio de Chirico, Joan Miro, Paul Klee, Frida Kahlo and Marc Chagall. During the 1990s, a number of Chinese painters – members of the Cynical Realism movement in Beijing – used symbolist motifs to express the political and social uncertainties arising after the crackdown at Tiananmen Square.
