This image shows a bust-length engraving of a man centered within an oval frame. The man is positioned facing slightly towards the right, with direct eye contact with the viewer. His facial features include a prominent nose, full cheeks, and a short, well-kept beard and mustache, while his hair is styled in loose curls around his head. He is depicted wearing an ornate outfit typical of nobility, including a high, broad lace collar, a richly embroidered garment embellished with pearls, and a draped sash over one shoulder. Around his neck hangs a delicate chain. The border contains detailed engravings of armor, helmets, and weapons. The background consists of the decorative oval border itself, which contains text identifying the subject as Carolus Gonzaga and marking his titles. Below the portrait, there are further inscriptions and text likely attributing authorship or describing the subject.
