Here we end this long survey of the legendary literature of the Celt. The material is very abundant, and it is, of course, not practicable in a volume of this size to do more than trace the main current of the development of the legendary literature down to the time when the mythical and legendary element entirely faded out and free literary invention took its place. The reader of these pages will, however, it is hoped, have gained a general conception of the subject which will enable him to understand the significance of such tales as we have not been able to touch on here, and to fit them into their proper places in one or other of the great cycles of Celtic legend. It will be noticed that we have not entered upon the vast region of Celtic folk-lore. Folk-lore has not been regarded as falling within the scope of the present work. Folk-lore may sometimes represent degraded mythology, and sometimes mythology in the making. In either case, it is its special characteristic that it belongs to and issues from a class whose daily life lies close to the earth, toilers in the field and in the forest, who render with simple directness, in tales or charms, their impressions of natural or supernatural forces with which their own lives are environed. Mythology, in the proper sense of the word, appears only where the intellect and the imagination have reached a point of development above that which is ordinarily possible to the peasant mind—when men have begun to co-ordinate their scattered impressions and have felt the impulse to shape them into poetic creations embodying universal ideas. It is not, of course, pretended that a hard-and-fast line can always be drawn between mythology and folk-lore; still, the distinction seems to me a valid one, and I have tried to observe it in these pages.
