What is in this image? Describe it as if you were explaining it to someone from the 15th century.

The image depicts a simple, flat drawing of a man''s head and upper shoulders. He appears earnest or contemplative. His head is mostly bald, with some hair at the sides and back, and he wears rounded spectacles, which are like small circles of glass held before the eyes with a frame, a fairly modern invention useful for improving sight. He has a prominent mustache — that is, hair grown and maintained above the upper lip, a common style amongst some men. His attire suggests a garment draped over one shoulder, much like a toga or simplistic robe, which might remind you of classical depictions of scholars or philosophers. The drawing is clear and lacks color, consisting only of dark lines used to outline his features against a plain background. It''s rendered in a style that would be unfamiliar in your time, prioritizing simplicity and abstraction over detailed realism.
