Cubism The most influential style of the twentieth century, developed in Paris by Picasso and Braque, beginning in 1907. The early mature phase of the style, called Analytical Cubism, lasted from 1909 through 1911. Cubism is based on the simultaneous presentation of multiple views, disintegration, and the geometric reconstruction of objects in flattened, ambiguous pictorial so space; figure and ground merge into one interwoven surface of shifting planes.

Usually refers to linear perspective, which is based on the fact that parallel lines or edges appear to converge and objects appear smaller as the distance between them and the viewer increases. Atmospheric perspective (aerial perspective) creates the illusion of distance by reducing color saturation, value contrast, and detail in order to imply the hazy effect of atmosphere between the viewer and distant objects. Isometric perspective is not a visual or optical interpretation, but a mechanical means to show space and volume in rectangular forms. Parallel lines remain parallel; there is no convergence.

Post-Impressionist painters were concerned with the significance of form, symbols, expressiveness, and psychological intensity. They can be broadly separated into two groups, expressionists, such as Gauguin and Van Gogh, and formalists, such as C¾ zanne and Seurat.
Post-Modern An attitude or trend of the 1970s, 1980s, and 1990s, in which artists and architects accept all that modernism rejects. In architecture, the movement away from or beyond what had become boring adaptations of the International Style, in favor of an imaginative, eclectic approach. In the other visual arts, Post-Modern is characterized by an acceptance of all periods and styles, including modernism, and a willingness to combine elements of all styles and periods. Although modernism makes distinctions between high art and popular taste, Post-Modernism makes no such value judgments.

Surrealism A movement in literature and the visual arts that developed in the mid 1920s and remained strong until the mid1940s, growing out of Dada and automatism. Based upon revealing the unconscious mind in dream images, the irrational, and the fantastic, Surrealism took two directions: representational and abstract. Dali's and Magritte's paintings, with their uses of impossible combinations of objects depicted in realistic detail, typify representational Surrealism. MirÙ 's paintings, with their use of abstract and fantastic shapes and vaguely defined creatures, are typical of abstract Surrealism.
