caption: The image shows a portrait of a man in a black and white robe, sitting in a chair with a dark background. The man is believed to be Sir Thomas Rowlandson, as indicated by the text at the bottom of the painting. He has a serious expression on his face, and his hands are resting on the armrests of the chair. His hair is dark and his eyes are focused intently on something in the distance. He is wearing a white robe with a black collar and cuffs, and a black belt around his waist.
