But in the second place the Mabinogion all centre, in one way or another, about the court of King Arthur, and present us with views of the domestic life going on in King Arthur's palace, as well as of the wild adventures of his warriors, which were conceived at a very much earlier and ruder period than that of Sir Thomas Malory's book; so that this collection of the earliest Arthurian legends seemed to make a peculiarly happy companion-book to _The Boy's King Arthur_, which was last published in this series. Indeed, it is probable that in these Mabinogion here following we have the original germs of that great growth of Arthurian romances which overspread Europe after Geoffrey of Monmouth published his _History of the Britons_, and of which I gave some account in the Introduction to _The Boy's King Arthur_. Readers of that Introduction will remember the statement there given, in which Geoffrey of Monmouth himself declares that his main material consisted of a Welsh book given him by a certain person since supposed to be Walter Map (or Mapes). Although several of the following Mabinogion have probably received additions from foreign sources in the course of time--an original Welsh story, for example, would be carried by some traveller into other parts of Europe, would there be retold with additions and variations, would find its way back in the new form to Wales, and thus re-appear after a while in Welsh collections; yet others are in a nearly pure state. In order to bring these two classes into striking contrast, and to show how much a foreign admixture of this kind might smooth down the grotesque ruggedness of its Welsh original, I have changed the order of the Mabinogion as given in Lady Guest's arrangement, and have placed the story of _Kilhwch and Olwen_, which is almost hideous in many of its huge fancies and distortions and is pure Welsh, immediately next to the story of _The Lady of the Fountain_, whose daintiness, luxury, black savages, and the like, seem here and there to indicate foreign touches. The general tone and essential spirit, however, of the whole, are distinctly Welsh, and old Welsh. I think it curious indeed to note _how_ curious those old romances, or Mabinogion, seem to us in spite of the long intimacy and nearness between Welsh and English. They impress most readers with a greater sense of foreignness, of a wholly different cultus, than even Chinese or other antipodal tales; and over and above this there is a glamour and sleep-walking mystery which often incline a man to rub his eyes in the midst of a Mabinogi, and to think of previous states of existence.
