To trace Welsh and Irish kings and saints and hermits back to “the elemental powers of earth and fire, and the spirits that haunted the woods and streams” of Celtic imagination, and to disclose primitive pagan deities under the mediæval and Christian trappings of “King Arthur’s Knights” will necessarily fall within the scope of this volume. But meanwhile the reader will probably be asking what evidence there is that apocryphal British kings like Lear and Lud, and questionable Irish saints like Bridget are really disguised Celtic divinities, or that the Morte D’Arthur, with its love of Launcelot and the queen, and its quest of the Holy Grail, was ever anything more than an invention of the Norman romance-writers. He will demand to know what facts we really possess about this supposed Celtic mythology alleged to have furnished their prototypes, and of what real antiquity and value are our authorities upon it. The answer to his question will be found in the next chapter. ----- Footnote 1: “There is good ground to believe”, writes Mr. E. W. B. Nicholson, M.A., the librarian of the Bodleian Library, in the preface to his recently-published _Keltic Researches_, “that Lancashire, West Yorkshire, Staffordshire, Worcestershire, Warwickshire, Leicestershire, Rutland, Cambridgeshire, Wiltshire, Somerset, and part of Sussex, are as Keltic as Perthshire and North Munster; that Cheshire, Shropshire, Herefordshire, Monmouthshire, Gloucestershire, Devon, Dorset, Northamptonshire, Huntingdonshire, and Bedfordshire are more so—and equal to North Wales and Leinster; while Buckinghamshire and Hertfordshire exceed even this degree and are on a level with South Wales and Ulster. Cornwall, of course, is more Keltic than any other English county, and as much so as Argyll, Inverness-shire, or Connaught.” Footnote 2: _The Study of Celtic Literature._ Footnote 3: In a sonnet written in 1801.
