Study for Man Making an Explosion 

This pen drawing by Giulio Bonasone, an Italian Renaissance artist known for his engravings, depicts a man in the act of making an explosion. The artist's meticulous detail and dynamic composition are evident in the swirling smoke and the figure's forceful movements. This study, likely a preparatory sketch for a larger work, demonstrates Bonasone's mastery of light and shadow, contributing to the dramatic and evocative nature of the scene.
