The end of the fourteenth century, when Geoffrey Chaucer wrote, was one of the periods of great accomplishment in English literature. Chaucer did not stand alone. Wiclif's prose, the admirable poetry that Gower composed in three languages, and the powerful satiric verse of Piers Plowman give ample evidence of this. Among the poets of the time no one except Chaucer was greater than the author of Sir Gawain and the Green Knight and The Pearl, whose name and personality are still unknown. Though a learned man of the world like Chaucer, he wrote in the dialect of northwestern England rather than of London, which must have seemed difficult to most readers even in his own time. Why he chose such an obscure dialect has never been understood. The writer of this paper calls attention to the eloquent defence of his native speech that Dante made in his Convivio, and suggests that the Gawain poet may have been inspired by it to do for his own dialect what the great Italian had done for Tuscan.
