Nineteenth-century theatrical scenery

Theatre in the nineteenth century was noted for its changing philosophy from the Romanticism and Neoclassicism that dominated Europe since the late 18th century to Realism and Naturalism in the latter half of the 19th century before it eventually gave way to the rise of Modernism in the 20th century. Scenery in theater at the time closely mirrored these changes, and with the onset of the Industrial Revolution and technological advancement throughout the century, dramatically changed the aesthetics of the theater.
