Surrealism is a style in which visual imagery, and literature is used, it was dedicated to the imagination as revealed in dreams, it was free of the conscious control of reason and free of convention, its emphasis was on positive expression. It flourished in Europe between World Wars I and II. Surrealism grew out of the earlier Dada movement. It was founded in 1924 in Paris by Andre Breton with his Manifeste du surrealism, according to him surrealism was a means of reuniting conscious and unconscious realms of experience, so completely that the world of dream and fantasy would be joined to the everyday rational world, in an absolute reality ,a surreality. Surrealism became dominant in the 1920s and 30s and was internationally practiced with many and varied forms of expression. Salvador Dali and Yves Tanguy used dreamlike perception of space and dream-inspired symbols such as melting watches and huge metronomes. "Absolute" surrealism depends upon images derived from psychic automatism, the subconscious or spontaneous thought. Surrealism as we know it is closely related to some forms of abstract art. The movement survived but was greatly diminished after World War II. An example of Surrealism would be Francis Picabia she did a painting called Sunlight On The Banks Of The Loing, it's a picture of a boat in the river and you can see the trees above the boat on the river, it is a very clear painting with use of lots of green colours and plenty of light.
