The materials crowded into the earlier chapters mark out the stories connected with the fairies, whether of the lakes or of the dry land, as the richest lode to be exploited in the mine of Celtic folklore. That work is attempted in the later chapters; and the analysis of what may briefly be described as the fairy lore given in the earlier ones carries with it the means of forcing the conviction, that the complex group of ideas identified with the little people is of more origins than one; in other words, that it is drawn partly from history and fact, and partly from the world of imagination and myth. The latter element proves on examination to be inseparably connected with certain ancient beliefs in divinities and demons associated, for instance, with lakes, rivers, and floods. Accordingly, this aspect of fairy lore has been dealt with in chapters vi and vii: the former is devoted largely to the materials themselves, while the latter brings the argument to a conclusion as to the intimate connexion of the fairies with the water-world. Then comes the turn of the other kind of origin to be discussed, namely, that which postulates the historical existence of the fairies as a real race on which have been lavishly superinduced various impossible attributes. This opens up a considerable vista into the early ethnology of these islands, and it involves a variety of questions bearing on the fortunes here of other races. In the series which suggests itself the fairies come first as the oldest and lowest people: then comes that which I venture to call Pictish, possessed of a higher civilization and of warlike instincts. Next come the earlier Celts of the Goidelic branch, the traces, linguistic and other, of whose presence in Wales have demanded repeated notice; and last of all come the other Celts, the linguistic [xii]ancestors of the Welsh and all the other speakers of Brythonic. The development of these theses, as far as folklore supplies materials, occupies practically the remaining five chapters. Among the subsidiary questions raised may be instanced those of magic and the origin of druidism; not to mention a neglected aspect of the Arthurian legend, the intimate association of the Arthur of Welsh folklore and tradition with Snowdon, and Arthur’s attitude towards the Goidelic population in his time.
