Prompt
Generate an image of a 19th-century British man with a thoughtful expression, sitting in a study surrounded by books and papers, with a pen in hand. He has a gentle face with a well-groomed beard and mustache, wearing a suit and tie. In the background, a large bookshelf and a window with a view of the city can be seen. The style should be realistic and reminiscent of Victorian-era portraiture. The man is George Henry Lewes, a philosopher, literary critic, biologist, and writer, circa 1850s.
