Late period It was with the fourteenth century that major works of English literature began once again to appear; these include the so-called Pearl Poet's Pearl, Patience, Cleanness, and Sir Gawain and the Green Knight; Langland's political and religious allegory Piers Plowman; John Gower's Confessio Amantis; and the works of Geoffrey Chaucer, the most highly regarded English poet of the Middle Ages, who was seen by his contemporaries as an English successor to the great tradition of Virgil and Dante.
The Kildare Poems are a rare example of Middle English literature produced in Ireland, and give an insight into the development of Irish English.
The latter portion of the 14th century also saw not only the consolidation of English as a written language, taking over from French or Latin in certain areas, but a large shift from primarily theological or religious subject matter to also include that of a more secular nature. Vernacular book production saw a growth in the number of books being copied, both secular and religious. Thus, the latter portion of the 14th century can be seen as one of the most significant periods in the history of the English language.
The reputation of Chaucer's successors in the 15th century has suffered in comparison with him, though Lydgate, Thomas Hoccleve, and Skelton are widely studied. At this time the origins of Scottish poetry began with the writing of The Kingis Quair by James I of Scotland. The main poets of this Scottish group were Robert Henryson, William Dunbar, and Gavin Douglas. Henryson and Douglas introduced a note of almost savage satire, which may have owed something to the Gaelic bardic poetry, while Douglas's version of Virgil's Aeneid is one of the early monuments of Renaissance literary humanism in English.
It was a vibrant time for religious drama as well: many morality plays and miracle plays were produced, and some scripts survive today. Sidrak and Bokkus is another example of late Middle English literature.
