Figurative art is a form of artwork that has existed for thousands of years in cultures all around the world. It retains strong references to the real world and particularly to the human figure in any of its various shapes and postures. There are no particular rules in how the figure may be illustrated. The degree of representation may range from highly detailed, anatomically correct renderings to loose and expressive sketches. In a few cases, creative figurative artworks look similar to abstraction. Picasso after about 1920 is the great exemplar of modern figurative painting.
