Neoclassical art flourished in Europe and North America from the mid to late 18th century as artists sought to replace the frivolity of Rococo with a more logical and solemn style. In architecture, the model was Ancient Rome and Greece, as seen in the works of architects like Ledoux, Percier and Fontaine. In sculpture, artists like Canova and Thorvaldsen emulated Classical Greek ideals using white marble. Painting centered in Rome, with artists like Jacques-Louis David creating grand historical works with simplified compositions inspired by mythology.
