The image is an engraved portrait showing the upper torso of a man. He is positioned at an angle facing slightly to his left, looking directly at the viewer. The man has a well-groomed mustache and beard, with short, wavy hair styled back from his forehead. He wears a detailed, historical outfit that includes a richly patterned garment with a high, elaborate lace ruff around his neck. There is no visible jewelry or objects being held by him. The background features a circular frame enclosing the portrait with text inscribed around it, which names the individual as Ioannes Ernestus Com. A Nassau.
