Little was done to secure the scientific satisfaction of curiosity about traditional folk-tales, contes or marchen till the time when the brothers Grimm collected the stories of Hesse. The Grimms became aware that the stories were common to the peasant class in most European lands, and that they were also known in India and the East. As they went on collecting, they learned that African and North American tribes also had their marchen, not differing greatly in character from the stories familiar to German firesides. Already Sir Walter Scott had observed, in a note to the Lady of the Lake, that "a work of great interest might be compiled upon the origin of popular fiction, and the transmission of similar tales from age to age, and from country to country. The mythology of one period would then appear to pass into the romance of the next, and that into the nursery tales of subsequent ages." This opinion has long been almost universal. Thus, if the story of Jason is found in Greek myths, and also, with a difference, in popular modern marchen, the notion has been that the marchen is the last and youngest form, the _detritus_ of the myth. Now, as the myth is only known from literary sources (Homer, Mimnermus, Apollonius Rhodius, Euripides, and so on), it must follow, on this theory, that the people had borrowed from the literature of the more cultivated classes. As a matter of fact, literature has borrowed far more from the people than the people have borrowed from literature, though both processes have been at work in the course of history. But the question of the relations of marchen to myths, and of both to romance, may be left unanswered for the moment. More pressing questions are, what is the origin, and where the original home of the marchen or popular tales, and how have they been so widely diffused all over the world? The answers given to these questions have naturally been modified by the widening knowledge of the subject. One answer seemed plausible when only the common character of European _contes_ was known; another was needed when the Aryan peoples of the East were found to have the same stories; another, or a modification of the second, was called for when marchen like those of Europe were found among the Negroes, the Indians of Brazil, the ancient Huarochiri of Peru, the people of Madagascar, the Samoyeds, the Samoans, the Dene Hareskins of the extreme American North-west, the Zulus and Kaffirs, the Bushmen, the Finns, the Japanese, the Arabs, and the Swahilis.
