First impressions of mediaeval life are usually coloured by the courtly romances of Malory and his later refiners. Chaucer brings us down to reality, but his people belong to a prosperous middle-class world, on holiday and in holiday mood. Piers Plowman stands alone as a revelation of the ignorance and misery of the lower classes, whose multiplied grievances came to a head in the Peasants' Revolt of 1381.
