Besides Geoffrey Chaucer and William Langland, which author is also recognized for contributing to the flourishing of Middle English literature?

Explanation

While Geoffrey Chaucer and William Langland are central figures in Middle English literature, the Gawain poet is another important contributor to this literary period. Geoffrey of Monmouth and Chrétien de Troyes were influential in medieval literature but not specifically within Middle English. Similarly, the Beowulf poet wrote in Old English, preceding the Middle English era.
