Prompt
Generate a realistic portrait of John Couch Adams, a British mathematician and astronomer, in a 19th-century style. He should be depicted in a formal attire, possibly with a suit and tie, and holding a book or a scientific instrument, such as a celestial globe or a telescope. In the background, a subtle image of a astronomical chart or a map of the solar system should be visible, hinting at his work on the prediction of Neptune. The overall mood should be one of contemplation and intellectual curiosity.
