Abstraction is a departure from accurate representation of visual reality. It is often non-figurative and non-objective. Abstract art utilizes interpretation of shape, form, line and color to create composition and meaning (or lack thereof). From the Renaissance until the middle 19th century, art had been underpinned by an attempt to emulate and reproduce that which was seen as reality. By the end of the 19th century, artists turned to abstract principles in order to develop a kind of outlet that would represent the changes taking place in society, technology, philosophy, and science. Abstraction also exists in early art, and in some cases helped artists represent religious and philosophical principles.
