CHAPTER XII.
GEOGRAPHICAL DISTRIBUTION OF MYTHS.
The student of the early History of Mankind finds in Comparative Mythology the same use and the same difficulty which lie before him in so many other branches of his subject. He can sometimes show, in the mythical tales current among several peoples, coincidences so quaint, so minute, or so complex, that they could hardly have arisen independently in two places, and these coincidences he claims as proofs of historical connexion between the tribes or nations among whom they are found. But his great difficulty is how to be sure that he is not interpreting as historical evidence analogies which may be nothing more than the results of the like working of the human mind under like conditions. His ever-recurring problem is to classify the crowd of resemblances which are continually thrusting themselves upon him, so as to keep those things which are merely similar apart from those which, having at some spot of the earth's surface their common source and centre of diffusion, are really and historically united.
No attempt is made in the present chapter to lay down definite rules for the solution of this important problem, but a few illustrations are given of the more general analogies running through the Folk-lore of the world, which Ethnology, for the present at least, has to set aside; and then a few facts are stated, bearing on the diffusion of Myths by recognised channels of intercourse, with the view of introducing a group of similar episodes, which it is for the reader to reject as caused by independent growth or modern transmission, or to accept as a contribution to the early History of the New World.
Firstly, then, there are found among savage tribes myths like
