One of the most admired artists of the twentieth century, Max Ernst was a proponent of Dada and founder of surrealism, known for his strange, evocative paintings and drawings. In Prehistoric Future, Ralph Ubl approaches Ernst like no one else has, using theories of the unconscious—surrealist automatism, Freudian psychoanalysis, the concept of history as trauma—to examine how Ernst’s construction of collage departs from other modern artists.
