Because every art form is a perspective and there is no art that shows reality. It just shows the perspective.
In the arts, realism refers to a realistic, detailed, and unembellished representation of nature or modern life. The idealization of the imagination is rejected by realism in favor of a rigorous examination of outer manifestations. As a result, many aesthetic currents in various civilizations have been categorized as realism in its broad sense. For instance, ancient Hellenistic Greek sculptures of boxers and aged women accurately capture realism in the visual arts. Realist techniques can be seen in the works of 17th-century painters like Caravaggio, Dutch genre painters, Spanish painters José de Ribera, Diego Velázquez, and Francisco de Zurbarán, as well as French painters the Le Nain brothers.
Realistic novels include those by English authors Daniel Defoe, Henry Fielding, and Tobias Smollett from the 18th century.
