The image depicts a portrait of a man with only his head and shoulders shown. He is positioned slightly angled to his right, facing the viewer. The man appears aged with furrowed brows, deep-set eyes, a bulbous nose, and a long beard with a slight curl at the end. He has a closely trimmed mustache and some visible hair along his forehead and sides, leading into his beard. The man wears a square cap hat and a robe with a visible collar secured by a few buttons. The image is framed within an oval design with intricate patterns and text around the perimeter identifying him as Marcus Antonius de Dominis. The background is cross-hatched, providing a textured contrast to the detailed figure.
