in Dryden's satire of Absalom and Achitophel is designed for the Duchess of Monmouth. Her maiden name and title were Anne Scott, Countess of Buccleuch, the richest heiress in Europe. The duke was faithless to her, and after his death, the widow, still handsome, married again.
“To all his [Monmouth's] wishes, nothing he [David] denied; And made the charming Annabel his bride.”
Part i. lines 33, 34.
