Prompt
Create a realistic portrait of Thomas Henry Huxley, a middle-aged British biologist and anthropologist from the 19th century, with a strong and determined facial expression, wearing formal attire, including a suit and tie, sitting in a study with books and scientific instruments in the background, reflecting his work in evolutionary biology, comparative anatomy, and paleontology, and his advocacy for Charles Darwin's theory of evolution, with a hint of introspection and intellectualism, in the style of a Victorian-era photograph.
