The landscape painter

Caspar David Friedrich (September 5, 1774 - May 7, 1840) was a landscape painter of the nineteenth-century German Romantic movement, of which he is now considered the most important painter. A painter and draughtsman, Friedrich is best known for his later allegorical landscapes, which feature contemplative figures silhouetted against night skies, morning mists, barren trees, and Gothic ruins. His primary interest as an artist was the contemplation of nature, and his often symbolic and anti-classical work seeks to convey the spiritual experiences of life.
Friedrich was born in Greifswald in northern Germany in 1774. He studied in Copenhagen until 1798 before settling in Dresden. He came of age during a period when, across Europe, a growing disillusionment with an over-materialistic society led to a new appreciation for spiritualism. This was often expressed through a reevaluation of the natural world, as artists such as Friedrich, J. M. W. Turner and John Constable sought to depict nature as a "divine creation, to be set against the artifice of human civilization".
