Marmion: A Tale of Flodden Field, a historical romance written in verse about 16th-century Scotland by Sir Walter Scott, was published in 1808. Austen mentions this book of poetry in Persuasion through the character of Captain Benwick, who is "evidently a young man of considerable taste in reading, though particularly in poetry" (Austen 129). Anne and Benwick then discuss which books they favor over others as they get to know one another, which is when Marmion: A Tale of Flodden Field is mentioned (Austen 129).
