Today, Caspar David Friedrich is considered the most important artist of German Romanticism. Johann Wolfgang von Goethe, in turn, was one of the best connoisseurs of Friedrich's works at the time. This volume is dedicated to the hitherto little-noticed mutual attraction between the two personalities and demonstrates the central role of Weimar in art around 1800. For the first time, it presents the outstanding holdings of Friedrich's works from the collection of the Klassik Stiftung Weimar. The latest restoration studies also raise awareness of the cultural value of this pictorial treasure.
