The image shows an older man in a side profile, focusing on his upper body and head. He is seated with his head turned slightly downward, engaging with an open book held close to his face. The man has distinctive facial features, including a prominent bald head and a full, bushy beard. He is wearing a garment draped over his shoulders, though specific details of the clothing are obscured by the monochrome shading. There is no visible jewelry. The background is a simple, textured surface without any distinct patterns or objects, and the image is framed by a drawn border with a caption below that reads "Sanctus Matthaeus."
