Often called the first great English novel, Troilus and Cressida, a tragic love story set during the siege of Troy, is Chaucer's masterpiece. Troilus, a valiant warrior, is scornful of love until he catches a glimpse of Cressida. With the help of his friend and her uncle Pandarus, Troilus wins Cressida over. But their happiness is destroyed when, summoned to a Greek camp, Cressida seeks the protection of one Diomede and ultimately betrays Troilus.
