THOPAS is the hero of The Tale of Sir Thopas, Chaucer's parody of the romances current in his day. He is named for the semiprecious stone topaz, which, in medieval lapidaries, was linked to all the virtues, including chastity. It was prized among the nobility in Chaucer's day. Sir Thopas is to other splendid knights of renowned romances as the topaz is to other gems. [Beves: Gy: Horn: Lybeux: Oliphant: Percyvell: Pleyndamour: Termagaunt: Ypotis]
