An international artistic movement of the late 19th and early 20th centuries that emphasized the unity of the arts and sought to reflect the intensive psychic and sensory stimuli of the modern city. Although it influenced painting and sculpture, the movement’s chief manifestations were in design, performance art, and architecture. Variants of the movement in cities throughout Europe and the US accrued labels such as Arte Nova, Glasgow Style, Stile Liberty, and Arte Modernista. The version commonly referred to as Art Nouveau (“New Art” in French) flourished in France and Belgium and was characterized by curving, uneven lines based on organic forms.
