 Several of Hammer's works were published by Heinrich Rittner, a Dresden art dealer, in the volume "Dresden mit seinen Pachtgebäuden und schönsten Umgebungen" ("Dresden with her splendid buildings and beautiful surroundings").An 1810 volume printed by Carl Christian Meinhold had prompted a great deal of interest in Dresden at that time.Hammer was one of the first painters to discover the pristine water world of the Spreewald; he created several high-romantic pictures of this unique European landscape.
