The engraving shows a portrait from the chest up of a man named Nicolaus Reusnerus. He is positioned facing forward and slightly to the left, with a large, elaborate hat featuring a wide band adorned with a circular emblem. His facial features include a rounded face, prominent cheekbones, bushy eyebrows, and a long, full beard that extends down past his collared shirt. He is wearing a ruff or pleated collar around his neck and a cloak draped over his shoulders. His right hand is partially visible, holding what appears to be sheets of paper or a small book. The background includes an architectural arch border and decorative elements such as flowers and butterflies. The top of the engraving displays the name "NICOLAUS REUSNERUS IC."
