Piers Plowman (written ca. 1360–1387) or Visio Willelmi de Petro Plowman (William`s Vision of Piers Plowman) is the title of a Middle English allegorical narrative poem by William Langland. It is written in unrhymed alliterative verse divided into sections called "passus" (Latin for "step"). Piers is considered by many critics to be one of the early great works of English literature along with Chaucer`s Canterbury Tales and Sir Gawain and the Green Knight during the Middle Ages.
