Prompt
Create a realistic portrait of Sir Archibald Geikie, a middle-aged British geologist and author from the late 19th and early 20th centuries, dressed in formal attire, with a backdrop that subtly reflects his work in geology, such as a landscape with Scottish scenery or geological formations, and include elements that signify his achievements, such as a medal or a book, in a style that blends traditional realism with a touch of historical detail.
