Representational art describes artworks – particularly paintings and sculptures – that are clearly derived from real object sources, and therefore are by definition representing something with strong visual references to the real world. Most, but not all, abstract art is based on imagery from the real world. The most "extreme" form of abstract art is not connected to the visible world and is known as representational. Representational art or figurative art represents objects or events in the real world, usually looking easily recognizable. For example, a painting of a cat looks very much like a cat – it's quite obvious what the artist is depicting. Romanticism, Impressionism, and Expressionism contributed to the emergence of abstract art in the nineteenth century as artists became less interested in depicting things exactly like they really exist. Abstract art exists on a continuum, from somewhat representational work, to work that is so far removed from its actual real-world appearance that it is almost impossible to easily discern what is being represented. Abstract art is always connected to something visual from the real world. Work that does not depict anything from the real world (figures, landscapes, animals, etc.) is called nonrepresentational. Nonrepresentational art may simply depict shapes, colors, lines, etc., but may also express things that are not visible – emotions or feelings for example. This figurative or representational work from the seventeenth century depicts easily recognizable objects–ships, people, and buildings.

Three movements that contributed heavily to the development of these were Romanticism, Impressionism, and Expressionism. Abstract
