The image is an engraving showing a seated man identified as M. de Voltaire. He is angled towards the right side of the frame while engaged in writing or reading a document on a desk. His head is slightly bowed forward as he looks down at the papers, showcasing a profile with a prominent nose and distinct chin. The man wears a coat with fur trim and is adorned with a large, voluminous curly wig, topped by a hat with a folded brim. He appears focused on the task at hand, with his hands resting on the desk. The background is a simple wall with cross-hatched shading, and beside him, there are books and possibly a magnifying glass on the desk, with an elaborately carved chair partially visible behind him.
