Mönch an einer Türe klopfend 

"Mönch an einer Türe klopfend" is a watercolor painting by German artist Johann Heinrich Hasselhorst, created in the 19th century. The artwork depicts a monk standing at a door, his hand raised in a gesture of knocking. Hasselhorst was known for his detailed and realistic depictions of religious figures, and this piece is a prime example of his skill. The subtle use of light and shadow creates a sense of depth and realism, while the monk's solemn expression evokes a sense of piety and contemplation. This piece is currently held in the Städel Museum.
