A central idea of Classical Realism is the belief that the Modern Art movements of the 20th century opposed the tenets and production of traditional art and caused a general loss of the skills and methods needed to produce it. Modernism was antagonistic to art as it was conceived by the Greeks, resurrected in the Renaissance, and carried on by the academies of the nineteenth and early twentieth centuries. Classical Realist artists attempt to revive the idea of art production as it was traditionally understood: mastery of a craft in order to make objects that gratify and ennoble those who see them. This craftsmanship is then applied to drawing, painting or sculpting contemporary subjects which the artist observes in the modern world.
