Prompt
Generate a realistic portrait of William Barton Rogers, a middle-aged American man from the 19th century, dressed in formal attire, with a gentle expression, set against a subtle background that hints at his connection to geology and education, such as a faint image of a rock or a book; he should be seated in a comfortable, ornate chair, with a thoughtful gaze, wearing a suit and tie typical of his era, and possibly holding a book or a geological specimen; the style should be reminiscent of a formal portrait from the 1800s, with attention to detail and a sense of dignity.
