Felsige Landschaft mit Burgruine 

Franz Kobell's "Felsige Landschaft mit Burgruine" is a detailed pen and ink drawing depicting a rocky landscape with a ruined tower, likely inspired by his travels through the German countryside. The artist's masterful use of hatching and cross-hatching creates a sense of depth and texture, capturing the rugged beauty of the natural world. The ruined tower, perched atop a rocky outcrop, adds a touch of melancholy and history to the scene. This drawing is a fine example of Kobell's skill in depicting landscapes with both precision and poetic sensibility.
