The beauty of nature and man's loneliness are dominant themes in the work of Caspar David Friedrich (1774-1840). The artist often places a small human figure in a broad landscape, as in his famous paintingsMonk by the Sea and The Wanderer above the Sea of Fog. For a long time the importance and influence of this great Romantic painter were underestimated. When he died, Friedrich had already been forgotten by his contemporaries and was only rediscovered in the early 20th century. Today he is considered to be themost important German painter of his generation and a precursor of Expressionism. Once Friedrich gave the following advice to an artist-colleague of his who was constricted by academic rules: "Shut your physical eye so that you first see your painting with your spiritual eye. Then bring to light what you saw in the dark so that it has an effect on others, shining inwards from outside." In other words, concentration and not imitation, essence and not frivolous brushwork.
