Prompt
Generate a realistic portrait of Abraham Geiger, a German rabbi, scholar, and theologian, in a 19th-century style. Depict him sitting in a study, surrounded by books and papers, with a thoughtful expression. He should be dressed in formal attire, including a black suit, white shirt, and a rabbinic collar. In the background, include subtle hints of his notable works, such as "Urschrift und Übersetzungen der Bibel" and "Das Judenthum und seine Geschichte". The color palette should be muted, with earth tones and soft lighting, evoking a sense of intellectualism and contemplation.
