Troilus and Criseyde by Geoffrey Chaucer. Troilus and Criseyde is an epic poem by Geoffrey Chaucer which re-tells in Middle English the tragic story of the lovers Troilus and Criseyde set against a backdrop of war during the Siege of Troy. It was composed using rime royale and probably completed during the mid 1380s. Many Chaucer scholars regard it as the poet's finest work. As a finished long poem it is more self-contained than the better known but ultimately unfinished Canterbury Tales. This poem is often considered the source of the phrase: "all good things must come to an end." Calchas, a soothsayer, foresees the fall of Troy and abandons the city in favour of the Greeks; his daughter, Criseyde, receives some ill will on account of her father's betrayal. Troilus, a warrior of Troy, publicly mocks love and is punished by the God of Love by being struck with irreconcilable desire for Criseyde, whom he sees passing through the temple. With the help of sly Pandarus, Criseyde's uncle, Troilus and Criseyde begin to exchange letters. Eventually, Pandarus develops a plan to urge the two into bed together; Troilus swoons when he thinks the plan is going amiss, but Pandarus and Criseyde revive him. Pandarus leaves, and Troilus and Criseyde spend a night of bliss together.
