Prompt
Create an image of Ernst Haeckel, a German biologist, naturalist, philosopher, and artist, sitting at a desk surrounded by papers, books, and artistic sketches, with a thoughtful expression, wearing attire typical of the late 19th century, incorporating elements that reflect his contributions to science and art, such as a phylogenetic tree in the background, sketches of marine organisms, and a copy of his book "Kunstformen der Natur" nearby, in a realistic and detailed style.
