Caspar David Friedrich - Abendlicher Wolkenhimmel, Abend (1824)

Caspar David Friedrich (1774–1840) 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.
