caption: The image shows a painting of a young woman in a white dress, identified as Mary, painted by Sir Thomas Rowlandson. She is standing in front of a backdrop of trees, with a gentle expression on her face. Her dress is a light, airy fabric with a high neckline and long sleeves, and her hair is pulled back in a neat bun. Her hands are clasped in her lap and her gaze is directed towards the viewer, giving the painting a sense of serenity and grace.
