Prompt
Generate a realistic portrait of a 18th-century Scottish gentleman, specifically Lord Dreghorn, John Maclaurin, a middle-aged man with a dignified expression, wearing formal attire, including a wig and a robe, set against a backdrop that subtly suggests his connection to mathematics and justice, possibly incorporating a faint image of a mathematical diagram or a law book, in the style of a formal oil painting from the 18th century.
