Prompt

Create a realistic portrait of Parthenope Nightingale, a British writer and biographer, sitting in a elegant Victorian-era interior, possibly at Claydon House, her residence. She should be depicted as a woman of the 19th century, dressed in formal attire, with a thoughtful expression, surrounded by books and writing materials, reflecting her occupation as a writer and biographer, notable for her work on the biography of Mary Somerville. The style should be that of a formal Victorian-era portrait, with attention to historical detail.
