caption: The image shows a portrait of a woman in a white dress, painted by Sir Thomas Rowlandson, sitting in a chair with a dog by her side. She has a gentle expression on her face and her hands are resting on her lap. Her hair is pulled back in a neat bun and she is wearing a light-colored dress with a patterned shawl draped over her shoulders. The dog is a medium-sized breed with a white and brown coat. The background is a soft, muted color, giving the painting a peaceful and serene atmosphere.
