The document discusses Cubism and Surrealism. Cubism originated in the early 20th century and was one of the first abstract art styles. It used simple shapes and ignored color initially, giving depth and richness to paintings through overlapping fragments. Surrealism emerged in the 1920s and aimed to include unconscious thoughts and dreams in art by setting the imagination free, resulting in works that were odd, illogical, and irrational. Key Cubist artists included Pablo Picasso and George Braque, while Surrealist works often used techniques like automatic drawing and frottage to access the subconscious.
