CHASTELARD, PIERRE DE BOCOSEL DE

born 1540, Dauphin, Fr. died 1563, St. Andrews, Fife, Scot. French courtier whose passion for Mary Stuart, Queen of Scots, eventually led to his execution. Grandson of Pierre Terrail, chevalier de Bayard, Chastelard became page to the constable Montmorency and frequented the court of Francis II of France, where he fell in love with the queen consort, Mary, who is said to have encouraged his passion. He wrote poems to her and, after the death of Francis, was in the party escorting Mary back to Scotland in 1561. After returning to France, he revisited Edinburgh the next year and spent the winter at court at Holyroodhouse. There he hid himself under her bed, where he was discovered by her maids of honour. Mary pardoned the offense, but Chastelard was so rash as to repeat the same violation of her privacy. He was discovered again, seized, sentenced, and hanged the next morning. His story is the subject of Algernon Charles Swinburne's verse drama Chastelard (1865).
