Prompt
Create a realistic portrait of John Mercer Langston, a prominent African-American figure from the 19th century, dressed in formal attire, reflecting his roles as a lawyer, educator, diplomat, and politician, with a backdrop that subtly suggests his connection to the National Capitol, perhaps with a hint of a law book, a educational seal, or a diplomatic emblem in the scene, in a dignified and respectful style reminiscent of formal portraits from that era.
