Surrealist automatism

Surrealist automatism is a method of art-making in which the artist suppresses conscious control over the making process, allowing the unconscious mind to have great sway. Early 20th-century Dadaists, such as Hans Arp, made some use of this method through chance operations. Surrealist artists, most notably André Masson, adapted to art the automatic writing method of André Breton and Philippe Soupault who composed with it Les Champs Magnétiques (The Magnetic Fields) in 1919.[1] The Automatic Message (1933) was one of Breton's significant theoretical works about automatism.
