From this survey of the field of Celtic folk-tales it is clear that Ireland and Scotland provide the lion's share. The interesting thing to notice is the remarkable similarity of Scotch and Irish folk-tales. The continuity of language and culture between these two divisions of Gaeldom has clearly brought about this identity of their folk-tales. As will be seen from the following notes, the tales found in Scotland can almost invariably be paralleled by those found in Ireland, and _vice versâ_. The result is a striking confirmation of the general truth that the folk-lores of different countries resemble one another in proportion to their contiguity and to the continuity of language and culture between them.
Another point of interest in these Celtic folk-tales is the light they throw upon the relation of hero-tales and folk-tales (classes 2 and 3 above). Tales told of Finn or Cuchulainn, and therefore coming under the definition of hero-tales, are found elsewhere told of anonymous or unknown heroes. The question is, were the folk-tales the earliest, and were they localised and applied to the heroes, or were they heroic sagas generalised and applied to an unknown [Greek: _tis_]? All the evidence, in my opinion, inclines to the former view, which, as applied to Celtic folk-tales, is of very great literary importance; for it is becoming more and more recognised, thanks chiefly to the admirable work of Mr. Alfred Nutt, in his _Studies on the Holy Grail_, that the outburst of European Romance in the twelfth century was due, in large measure, to an infusion of Celtic hero-tales into the literature of the Romance-speaking nations. Now the remarkable thing is, how these hero-tales have lingered on in oral tradition even to the present day. (See a marked case in "Deirdre.") We may, therefore, hope to see considerable light thrown on the most characteristic spiritual product of the Middle Ages, the literature of Romance and the spirit of chivalry, from the Celtic folk-tales of the present day. Mr. Alfred Nutt has already shown this to be true of a special section of Romance literature, that connected with the Holy Grail, and it seems probable that further study will extend the field of application of this new method of research.
