Prompt
Generate a realistic portrait of Samuel Quincy, a 18th-century American lawyer and politician, in a formal attire, set against a subtle background that hints at his connection to Boston or the American colonies, reflecting his roles as Solicitor General of Massachusetts and his involvement in the Boston Massacre trials, with a hint of loyalty to the British Crown, considering his self-description as a loyalist, in the style of a classical oil painting from the 18th century.
