The Canterbury Tales consists of the stories related by the 29 pilgrims on their way to Saint Thomas Becket's shrine in Canterbury. Harry Bailey, the Host, had proposed a scheme in the General Prologue whereby each pilgrim was to narrate two tales on the way to Canterbury and two more while returning. In the course of the journey the Canon and his Yeoman join the pilgrims. However The Canterbury Tales are incomplete. There should have been a hundred and twenty tales in all according to the original plan but Chaucer only completed twenty-three tales. Out of these, the Cook's and the Squire's tales are unfinished. Two tales are imperfectly attributed to the teller: the Sea captain's tale begins as though a woman were telling it and was actually earlier meant for the Wife of Bath, while the Second Nun refers to herself as an "unworthy son of Eve". The Knight tells the first tale.
