Feudal England, the Middle Ages, the medieval period—these are names historians assign to a period of English history that lasted approximately from 500 to 1500 A.D. and that was gradually coming to an end during the life of one of England’s most celebrated writers, Geoffrey Chaucer, who was born in the early 1340s and lived till 1400. In The Canterbury Tales, Chaucer presents what today’s readers might consider snapshots of life in the late medieval period. Medieval people harbored similar hopes and nursed similar worries to those that occupy people today; yet the settings and activities of their daily life are now vanished into the remote past.
