Representational art refers to art which represents something, whether that be a tree in a landscape, apple in a still life, or figure in a portrait. Or in other words, it is art which is clearly identifiable as something which already exists in life.
Representational artwork aims to represent actual objects or subjects from reality. Subcategories under representational art include Realism, Impressionism, Idealism, and Stylization. All of these forms of representationalism represent actual subjects from reality. Although some of these forms are taking steps toward abstraction, they still fall under the category of representation. Representational art is perhaps the oldest of the three types of art.
