The history of the first division is the history of the breakdown just referred to. Except in the so-called _Chauceriana_--pieces such as "The Cuckoo and the Nightingale," "The Flower and the Leaf," "The Court of Love," etc., once attributed to Chaucer himself, but cast out on various kinds of evidence ranging from practically conclusive to very doubtful--and sometimes even in such poets as Lydgate and Occleve, who for no very small portion of their lives were Chaucer's own contemporaries, downwards, seem to be struck with metrical palsy or metrical blindness. Examples, given in the Scanned Conspectus above, will show the way in which they confuse different metres, vary the lengths of their lines not by intentional substitution but by sheer muddlement, violate rhythm and cadence--turn, in fact, the perfect harmony of their master into a cacophony which is not even prosaic. Sometimes, especially in Occleve, by rigid counting of syllables, they escape worse blunders, though they seldom make real music. Generally, even this resource fails them, and there is no worse chaos than in Hawes, one of the latest and not one of the least of them; while Skelton, perhaps the acutest intelligence of all, takes refuge in frank, _not_ clumsy, and intentional doggerel.
To this spectacle of disorganisation and decay the Scottish followers of Chaucer (who, generally with acknowledgment as eager and hearty as that of their English comrades, take him for their master) present what may at first sight seem an astonishing and almost unintelligible contrast. With final _e_'s allowed for (or in case of necessity touched in), the _Kingis Quair_, traditionally ascribed, and never with solid reason denied, to James the First, is a piece of rhyme-royal as soundly constructed, and as well fitted and polished, as if it were Chaucer's own. Henryson, in his following of Chaucer's _Troilus_, and in his other poems, never breaks down in metre, but handles every form that he touches with equal precision and charm. Even more may be said of Dunbar, whose lyrics possess the peculiar grace only given by metrical accomplishment, who can manage alliterative metre more smoothly than Langland and with not less vigour, and who, if he wrote the "Friars of Berwick," is, next to Chaucer himself, the greatest master of the early (Middle English) heroic couplet. Of the verse-chroniclers, Wyntoun, though not very poetical, uses octosyllabic couplet, with not infrequent equivalence, effectively enough, and Blind Harry writes very strict decasyllabic couplet with cæsura at the fourth syllable, after the French model. The earlier sixteenth-century writers, Douglas and Lyndsay, if not perhaps quite impeccable, appear so beside Hawes and his fellows; while the two latest strictly Scots poets, Scott and Montgomerie, manage most complicated measures--reminding us of early French and Provençal, or of those of the English fourteenth century in lyric and drama--with unerring accuracy and finished grace. Of this strange contrast the simple fact of writing in a different dialect, requiring more care in imitation, may supply some explanation; the other fact, that this dialect was rather a literary convention than a vernacular speech, some more; and the higher quality of individual genius, more still; but a margin of surprise remains.
