Prompt
Create a portrait of Meriwether Lewis, a rugged yet refined American explorer, soldier, and politician, sitting in a contemplative pose, dressed in attire befitting his roles, with a backdrop that subtly suggests the vast expanse of the American wilderness he helped to chart, incorporating elements that reflect his association with the Lewis and Clark Expedition and his tenure as Governor of Upper Louisiana, in a realistic style reminiscent of early 19th-century American portraiture.
