Four male figures; two bearing large books on their shoulders and the other two wrestling 

This is a drawing by the Flemish Baroque painter Peter Paul Rubens, who was known for his dynamic compositions and exaggerated figures. This particular work is a study of the human form, featuring four male figures in various poses. Two figures are shown carrying large books, while the other two are engaged in a wrestling match. This work is characteristic of Rubens' interest in anatomy and the depiction of movement, which informed his monumental paintings. This drawing provides a glimpse into Rubens’ artistic process, showing his careful study of the human figure and the muscular anatomy of the male form. It is likely that Rubens used these sketches as preliminary studies for larger paintings.
