A dual biography reconstructs the lives of a seventeenth-century noble couple through letters, memoirs, and contemporary sources. It follows his family background, education, court connections, marriage, and elevation in rank, and describes his service as a royalist commander and regional governor during the civil conflict, including campaigns, sieges, and dealings with parliamentary authorities. The study also presents her writings, biographical notices, and their shared role as patrons of art and learning, drawing on portraits, manuscripts, and printed works. Editorial commentary accompanies extensive documentary excerpts to illuminate personality, reputation, and the controversies that surrounded their careers.
