Abstract art uses the 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. From the Renaissance up to the middle of the 19th century, Western art had been grounded by the logic of perspective and an attempt to directly reproduce visible reality. By the end of the 19th century, many artists felt a need to create a new kind of art. Abstraction represents a departure from reality in depiction of imagery in art. It exists on a wide spectrum, allowing artists the freedom to carve out their own niche in this style. Here, it loosely mimics the ancient Roman and Greek marble figures the cultures are known for.
