The poetry of the alliterative revival , the unexplained reemergence of the Anglo-Saxon verse form in the 14th cent., includes some of the best poetry in Middle English. The Christian allegory The Pearl is a poem of great intricacy and sensibility that is meaningful on several symbolic levels. Sir Gawain and the Green Knight, by the same anonymous author, is also of high literary sophistication, and its intelligence, vividness, and symbolic interest render it possibly the finest Arthurian poem in English. Other important alliterative poems are the moral allegory Piers Plowman, attributed to William Langland, and the alliterative Morte Arthur, which, like nearly all English poetry until the mid-14th cent., was anonymous.
The works of Geoffrey Chaucer mark the brilliant culmination of Middle English literature. Chaucer's The Canterbury Tales are stories told each other by pilgrims—who comprise a very colorful cross section of 14th-century English society—on their way to the shrine at Canterbury. The tales are cast into many different verse forms and genres and collectively explore virtually every significant medieval theme. Chaucer's wise and humane work also illuminates the full scope of medieval thought. Overshadowed by Chaucer but of some note are the works of John Gower.
