I hope I have made clear in the last chapter the connection between the various types of the Swan-maiden group of folk-tales. The one idea running through them all is that of a man wedding a supernatural maiden and unable to retain her. She must return to her own country and her own kin; and if he desire to recover her he must pursue her thither and conquer his right to her by undergoing superhuman penance or performing superhuman tasks,--neither of which it is given to ordinary men to do. It follows that only when the story is told of men who can be conceived as released from the limitations we have been gradually learning during the progress of civilization to regard as essential to humanity--only when the reins are laid upon the neck of invention,--is it possible to relate the narrative of the recovery of the bride. These conditions are twice fulfilled in the history of a folk-tale. They are fulfilled, first, when men are in that early stage of thought in which the limitations of man's nature are unknown, when speculations of the kind touched upon in our second chapter, and illustrated repeatedly in the course of this work, are received as undisputed opinions. They are fulfilled again when the relics of these opinions, and the memories of the mythical events believed in accordance with such opinions, are still operative in the mind, though no longer with the vividness of primitive times; when some of them still hold together, but for the most part they are decaying and falling to pieces, and are only like the faded rags of a once splendid robe which a child may gather round its puny form and make believe for the moment that it is a king. To the genuine credulity of the South-Sea Islander, and to the conscious make-believe of the Arab story-teller and the peasant who repeats the modern _märchen_, all things are possible. But to the same peasant when relating the traditional histories of his neighbours, and to the grave mediæval chronicler, only some things are possible, though many more things than are possible to us. The slow and partial advance of knowledge destroys some superstitions sooner, others later. Some branches of the tree of marvel flourish with apparently unimpaired life long after others have withered, and others again have only begun to fade. Hence, where the adventures of Tawhaki, the mythical New Zealander, are incredible, the legend of the origin of the Physicians of Myddfai from the Lady of the Lake may still be gravely accepted. Gervase of Tilbury would probably have treated the wild story of Hasan's adventures in the islands of Wák as what it is; but he tells us he has seen and conversed with women who had been captives to the Dracs beneath the waters of the Rhone, while a relative of his own had married a genuine descendant of the serpent-lady of that castle in the valley of Trets.
