But though it is right to be enthusiastic about what is really ancient in Cornwall,—and there is nothing so ancient as language,—it is equally right to be discriminating. The fresh breezes of antiquity have intoxicated many an antiquarian. Words, purely Latin or English, though somewhat changed after being admitted into the Cornish dictionary, have been quoted as the originals from which the Roman or English were in turn derived. The Latin _liber_, book, was supposed to be derived from the Welsh _llyvyr; litera_, letter, from Welsh _llythyr; persona_, person, from Welsh _person_, and many more of the same kind. Walls built within the memory of men have been admitted as relics of British architecture; nay, Latin inscriptions of the simplest character have but lately been interpreted by means of Cornish, as containing strains of a mysterious wisdom. Here, too, a study of the language gives some useful hints as to the proper method of disentangling the truly ancient from the more modern elements. Whatever in the Cornish dictionary cannot be traced back to any other source, whether Latin, Saxon, Norman, or German, may safely be considered as Cornish, and therefore as ancient Celtic. Whatever in the antiquities of Cornwall cannot be claimed by Romans, Saxons, Danes, or Normans, may fairly be considered as genuine remains of the earliest civilization of this island, as the work of the Celtic discoverers of Britain. The Cornish language is by no means a pure or unmixed language,—at least we do not know it in its pure state. It is, in fact, a mere accident that any literary remains have been preserved, and three or four small volumes would contain all that is left to us of Cornish literature. “There is a poem,” to quote Mr. Norris, “which we may by courtesy call epic, entitled ‘Mount Calvary.’ ” It contains 259 stanzas of eight lines each, in heptasyllabic metre, with alternate rhyme. It is ascribed to the fifteenth century, and was published for the first time by Mr. Davies Gilbert in 1826.(49) There is, besides, a series of dramas, or mystery-plays, first published by Mr. Norris for the University Press of Oxford, in 1858. The first is called “The Beginning of the World,” the second “The Passion of our Lord,” the third “The Resurrection.” The last is interrupted by another play, “The Death of Pilate.” The oldest MS. in the Bodleian Library belongs to the fifteenth century, and Mr. Norris is not inclined to refer the composition of these plays to a much earlier date. Another MS., likewise in the Bodleian Library, contains both the text and a translation by Keigwyn (1695). Lastly, there is another sacred drama, called “The Creation of the World, with Noah’s Flood.” It is in many places copied from the dramas, and, according to the MS., it was written by William Jordan in 1611. The oldest MS. belongs again to the Bodleian Library, which likewise possesses a MS. of the translation by Keigwyn in 1691.(50)
