Expressionists characteristically reject traditional ideas of beauty or harmony and use distortion, exaggeration, and other non-naturalistic devices in order to emphasize and express the inner world of emotion. The paintings of El Greco and Grünewald exemplify expressionism in this broad sense, but the term is also used of a late 19th and 20th century European and specifically German movement tracing its origins to Van Gogh, Edvard Munch, and James Ensor, which insisted on the primacy of the artist's feelings and mood, often incorporating violence and the grotesque.
