Juxtaposition refers to the placement of two or more contrasting or unexpected elements together in a work of art. In Surrealism, juxtaposition was often used as a way to create dreamlike and often unsettling images that challenged traditional notions of representation. Surrealist artists often combined seemingly unrelated images and objects to create a sense of disorientation and mystery in their artwork. Juxtaposition was a key element of Surrealist collage and photomontage, and was used to create works of art that explored the depths of the unconscious mind and the irrational aspects of human experience.
