Martyrium des Heiligen Johannes 

This pen and ink drawing, titled "Martyrium des Heiligen Johannes" (Martyrdom of Saint John), is by Italian artist Gaspare Diziani, known for his works in the Rococo style. The drawing depicts a scene of intense drama, featuring Saint John’s martyrdom and the figures surrounding him, capturing the tumultuous energy of the scene. It’s likely this drawing was a preparatory sketch for a larger painting. The dynamic composition and expressive lines create a sense of urgency and emotion, characteristic of Diziani’s work. This drawing, now in the Städel Museum, is a powerful example of the artist's skill in conveying a narrative through line and form.
