Landschaft mit Wasserfall, rechts auf dem Berg eine Ruine 

Franz Kobell's "Landschaft mit Wasserfall, rechts auf dem Berg eine Ruine" is a detailed pen and ink drawing depicting a picturesque landscape. The scene features a rushing waterfall cascading down rocky cliffs towards a tranquil pool of water. A solitary tree stands on the left bank, providing a sense of scale and inviting the viewer into the peaceful scenery. In the background, a ruined tower perches atop a hill, suggesting a past era and inviting contemplation of history. The drawing, housed in the Städel Museum, demonstrates Kobell's mastery of depicting nature with precision and poetic nuance, making it a captivating example of 18th-century landscape art.
