Discuss the modes of representation. Give one example for each mode

What will be an ideal response?

Essay responses should include these points:
Naturalism or realism is the lifelike descriptions of the visual appearance of the natural world. An example would be Adriaen van der Spelt and Frans van Mieris's Flower Piece with Curtain because the subject is recognizable and mimics the natural world.
Abstract works transform recognizable natural subjects into patterns or make them conform to ideals. O'Keeffe's Jack in the Pulpit, No. IV is an example of art that has recognizable forms, a flower, but it is transformed into geometric shapes and patterns.
Nonrepresentational works do not depict a recognizable natural subject. David Smith's Cubi XVII does not represent anything found in nature but is a combination of shapes and lines.
