caption: The image shows a painting of a man wearing a black robe and glasses, believed to be a portrait of Sir Thomas Rowlandson. He has a serious expression on his face, and his hands are clasped in front of him. His hair is dark and his eyes are focused intently on something in the distance. He is wearing a white collar and a black shawl draped over his shoulders. His hands are resting on his lap and his posture is upright and dignified.
