Although not immediately obvious to the untrained eye, both ancient and contemporary art depend on a great quantity of mathematical concepts. Artists vary scale, perspective, proportion and other ideas from mathematics in order to evoke a particular feeling, convey a particular idea, or represent a particular scene. Some artists, such as Jean Baptiste Camille Corot, use scale and proportion common to human experience in order to create "life-like" works, while other artists, such as Salvador Dali, use purposefully misleading elements of scale and perspective in order to craft surrealist images. Indeed entire schools of thought in art have centered on basic principles of mathematics--Corot is generally classified as part of the Realist movement and Dali generally classified as part of the Surrealist movement. Even colors, or hues, used by artists are related to mathematics--in order to create a desired color, for example, many mediums...
