The Canterbury Tales is a collection of stories written by Geoffrey Chaucer in the 14th century (two of them in prose, the rest in verse). The tales, some of which are originals and others not, are contained inside a frame tale and told by a collection of pilgrims on a pilgrimage from Southwark to Canterbury to visit the shrine of Saint Thomas Becket at Canterbury Cathedral. The Canterbury Tales are written in Middle English. Although the tales are considered to be his magnum opus, some believe the structure of the tales is indebted to the works of The Decameron, which Chaucer is said to have read on an earlier visit to Italy.
