                                            Create a realistic portrait of Horace Mann, an influential American educator, in a 19th-century style. Depict him as a middle-aged man with a serious expression, wearing formal attire typical of the era, such as a suit and tie. He should be seated in a study or library setting, surrounded by books and possibly a few educational or governmental symbols, reflecting his contributions to the American public school system and his roles as an educator, politician, and lawyer. Incorporate subtle elements that hint at his legacy, such as a small model of a school or a book titled "Annual Reports of the Secretary of the Board of Education of Massachusetts" in the background. The color palette should be muted, with warm tones to evoke a sense of nostalgia and respect. The overall mood should be contemplative, capturing Mann's dedication to education and his vision for a more enlightened society.
