Sketch of a leg 

This is a sketch on paper by the Italian painter Gaspare Diziani (1689-1767). It is currently part of the collection of the Städel Museum in Frankfurt am Main. The artwork is likely a preparatory sketch for a larger painting, and the subject appears to be a leg. This sketch demonstrates Diziani's skill in capturing anatomy and form, which would have been essential for his larger works, known for their graceful figures and elaborate compositions.
