The wide field of interest opened up in tales of this class is a fascinating one to the students of fairy mythology. The whole world seems to be the scene of such tales, and collectors of folk-lore in many lands have laid claim to the discovery of 'the original' on which the story of Rip van Winkle is based. It is an honour to American genius, to which I cannot forbear a passing allusion, that of all these legends, none has achieved so wide a fame as that which Washington Irving has given to our literature, and Joseph Jefferson to our stage. It is more than probable that Irving drew his inspiration from Grimm, and that the Catskills are indebted to the Hartz Mountains of Germany for their romantic fame. But the legends are endless in which occur this unsuspected lapse of time among supernatural beings, and the wandering back to the old home to find all changed. In Greece, it is Epimenides, the poet, who, while searching for a lost sheep, wanders into a cave where he slumbers forty-seven years. The Gaelic and Teutonic legends are well known. But our wonder at the vitality of this myth is greatest when we find it in both China and Japan. In the Japanese account a young man fishing in his boat on the ocean is invited by the goddess of the sea to her home beneath the waves. After three days he desires to see his old mother and father. On parting she gives him a golden casket and a key, but begs him never to open it. At the village where he lived he finds that all is changed, and he can get no trace of his parents until an aged woman recollects having heard of their names. He finds their graves a hundred years old. Thinking that three days could not have made such a change, and that he was under a spell, he opens the casket. A white vapour rises, and under its influence the young man falls to the ground. His hair turns grey, his form loses its youth, and in a few moments he dies of old age. The Chinese legend relates how two friends wandering amongst the ravines of their native mountains in search of herbs for medicinal purposes, come to a fairy bridge where two maidens of more than earthly beauty are on guard. They invite them to the fairy land which lies on the other side of the bridge, and the invitation being accepted, they become enamoured of the maidens, and pass what to them seems a short though blissful period of existence with the fairy folk. At length they desire to revisit their earthly homes and are allowed to return, when they find that seven generations have lived and died during their apparently short absence, they themselves having become centenarians.[46] In China, as elsewhere, the legend takes divers forms.
