Abstract art uses a visual language of shape, form, color and line to create a composition which may exist with a degree of independence from visual references in the world. By the end of the 19th century many artists felt a need to create a new kind of art which would encompass the fundamental changes taking place in technology, science and philosophy. Abstraction indicates a departure from reality in depiction of imagery in art. This departure from accurate representation can be slight, partial, or complete. See "Abstract art". Wikipedia.
