He has defined facial features, including a high forehead, arched eyebrows, deep-set eyes, a prominent nose, and a pointed beard with a well-groomed mustache. His hair is short and receding at the temples. He is dressed in a dark, elaborately patterned garment with a high, stiff lace collar. The background is plain, with an ornate coat of arms to the right of his head. The image is a historical engraving, with text identifying the man as Sir Robert Naunton and providing details on the engraver and the source of the painting.
