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 written in 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 The Canterbury Tales. This poem is often considered the source of the phrase: "all good things must come to an end" (3.615). Although Troilus is a character from Ancient Greek literature, the expanded story of him as a lover was of Medieval origin. The first known version is from Benoît de Sainte-Maure's poem Roman de Troie, but Chaucer's principal source appears to have been Boccaccio, who re-wrote the tale in his Il Filostrato. Chaucer attributes the story to a "Lollius" (whom he also mentions in The House of Fame), although no writer with this name is known. Chaucer's version can be said to reflect a less cynical and less misogynistic world-view than Boccaccio's, casting Criseyde as fearful and sincere rather than simply fickle and having been led astray by the eloquent and perfidious Pandarus. It also inflects the sorrow of the story with humour. The poem had an important legacy for later writers. Robert Henryson's Scots poem The Testament of Cresseid imagined a rambunctious fate for Criseyde not given by Chaucer. In historical editions of the English Troilus and Criseyde, Henryson's distinct and separate work was sometimes included without accreditation as an "epilogue" to Chaucer's tale. Other texts, for example, John Metham's Amoryus and Cleopes (c. 1449), adapt language and authorship strategies from the famous predecessor poem. Shakespeare's tragedy Troilus and Cressida, although much darker in tone, was also based in part on the material. Troilus and Criseyde is usually considered to be a courtly romance, although the generic classification is an area of significant debate in most Middle English literature. It is part of the Matter of Rome cycle, a fact which Chaucer emphasizes. (wikipedia.org) About the author: Geoffrey Chaucer (c. 1340s - 25 October 1400) was an English poet, author, and civil servant best known for The Canterbury Tales. He has been called the "father of English literature", or, alternatively, the "father of English poetry". He was the first writer to be buried in what has since come to be called Poets' Corner, in Westminster Abbey. Chaucer also gained fame as a philosopher and astronomer, composing the scientific A Treatise on the Astrolabe for his 10-year-old son Lewis. He maintained a career in the civil service as a bureaucrat, courtier, diplomat, and member of parliament. Among Chaucer's many other works are The Book of the Duchess, The House of Fame, The Legend of Good Women, and Troilus and Criseyde. He is seen as crucial in legitimising the literary use of Middle English when the dominant literary languages in England were still Anglo-Norman French and Latin. Chaucer's contemporary Thomas Hoccleve hailed him as "the firste fyndere of our fair langage" (i.e., the first one capable of finding poetic matter in English). Almost two thousand English words are first attested to in Chaucerian manuscripts. (wikipedia.org)
