Ever since almost exactly a hundred years ago the Grimms produced their Fairy Tale Book, folk-lorists have been engaged in making similar collections for all the other countries of Europe, outside Germany, till there is scarcely a nook or a corner in the whole continent that has not been ransacked for these products of the popular fancy. The Grimms themselves and most of their followers have pointed out the similarity or, one might even say, the identity of plot and incident of many of these tales throughout the European Folk-Lore field. Von Hahn, when collecting the Greek and Albanian Fairy Tales in 1864, brought together these common formul of the European Folk-Tale. These were supplemented by Mr. S. Baring-Gould in 1868, and I myself in 1892 contributed an even fuller list to the Hand Book of Folk-Lore. Most, if not all of these formul, have been found in all the countries of Europe where folk-tales have been collected. In 1893 Miss M. Roalfe Cox brought together, in a volume of the Folk-Lore Society, no less than 345 variants of Cinderella and kindred stories showing how widespread this particular formula was throughout Europe and how substantially identical the various incidents as reproduced in each particular country. It has occurred to me that it would be of great interest and, for folk-lore purposes, of no little importance, to bring together these common Folk-Tales of Europe, retold in such a way as to bring out the original form from which all the variants were derived. I am, of course, aware of the difficulty and hazardous nature of such a proceeding; yet it is fundamentally the same as that by which scholars are accustomed to restore the Ur-text from the variants of different families of MSS. and still more similar to the process by which Higher Critics attempt to restore the original narratives of Holy Writ. Every one who has had to tell fairy tales to children will appreciate the conservative tendencies of the child mind; every time you vary an incident the children will cry out, That was not the way you told us before.? The Folk-Tale collections can therefore be assumed to retain the original readings with as much fidelity as most MSS. That there was such an original rendering eminating from a single folk artist no serious student of Miss Cox's volume can well doubt. When one finds practically the same ?tags? of verse in such different dialects as Danish and Romaic, German and Italian, one cannot imagine that these sprang up independently in Denmark, Greece, Germany, and Florence. The same phenomenon is shown in another field of Folk-Lore where, as the late Mr. Newell showed, the same rhymes are used to brighten up the same children?s games in Barcelona and in Boston; one cannot imagine them springing up independently in both places. So, too, when the same incidents of a fairy tale follow in the same artistic concatenation in Scotland, and in Sicily, in Brittany, and in Albania, one cannot but assume that the original form of the story was hit upon by one definite literary artist among the folk. What I have attempted to do in this book is to restore the original form, which by a sort of international selection has spread throughout all the European folks.
