Iwain and Gawain and The Wars of Alexander belong to quite the beginning of the fifteenth century, and they appear to be among the latest examples of the literary use of dialect in the North of England considered as a vehicle for romances; but we must not forget the “miracle plays,” and in particular The Towneley Mysteries or plays acted at or near Wakefield in Yorkshire, and The York Plays, lately edited by Miss Toulmin Smith. Examples of Southern English likewise come to an end about the same time; it is most remarkable how very soon, after the death of Chaucer, the Midland dialect not only assumed a leading position, but enjoyed that proud position almost alone. The rapid loss of numerous inflexions, soon after 1400, made that dialect, which was already in possession of such important centres as London, Oxford, and Cambridge, much easier to learn, and brought its grammar much nearer to that in use in the North. It even compromised, as it were, with that dialect by accepting from it the general use of such important words as they, their, them, the plural verb are, and the preposition till. There can be little doubt that one of the causes of the cessation of varying forms of words in literary use was the civil strife known as the Wars of the Roses, which must for a brief period have been hostile to all literary activity; and very shortly afterwards the printing-presses of London all combined to recognise, in general, one dialect only.
Hence it came about, by a natural but somewhat rapid process, that the only dialect which remained unaffected by the triumph of the Midland variety was that portion of the Northern dialect which still held its own in Scotland, where it was spoken by subjects of another king. As far as literature was concerned, only two dialects were available, the Northumbrian of Scotland and the East Midland in England. It is obvious that the readiest way of distinguishing between the two is to call the one “Scottish” and the other “English,” ignoring accuracy for the sake of practical convenience. This is precisely what happened in course of time, and the new nomenclature would have done no harm if the study of Middle English had been at all general. But such was not the case, and the history of our literature was so much neglected that even those who should have been well informed knew no better than others. The chief modern example is the well-known case of that most important and valuable book entitled An Etymological Dictionary of the Scottish Language, by John Jamieson, D.D., first published in Edinburgh in 1808. There is no great harm in the title, if for “Language” we read “Dialect”; but this great and monumental work was unluckily preceded by a “Dissertation on the Origin of the Scottish Language,” in which wholly mistaken and wrongheaded views are supported with great ingenuity and much show of learning. In the admirable new edition of “Jamieson” by Longmuir and Donaldson, published at Paisley in 1879, this matter is set right. They quite rightly reprint this “Dissertation,” which affords valuable testimony as to the study of English in 1808, but accompany it with most judicious remarks, which are well worthy of full repetition.
