In the middle of the 19th century—a time of change, as Emperor Napoleon III rebuilt Paris and waged war—the Académie des Beaux-Arts dominated French art. The Académie was the preserver of traditional French painting standards of content and style. Historical subjects, religious themes, and portraits were valued; landscape and still life were not. The Académie preferred carefully finished images that looked realistic when examined closely. Paintings in this style were made up of precise brush strokes carefully blended to hide the artist's hand in the work. Colour was restrained and often toned down further by the application of a golden varnish.
