This result is unavoidable if we remember also the past history of these countries. They have been swept over by nations, one more barbarous than another, one more ruthless than another, and none remaining there long enough to become a decisive factor in the formation of the existing nationalities. Dacians and Pelasgians, Romans and Goths, Petchenegs and Cumans, Alans and Huns, Tartars and Hungarians, Bulgars, Slavs and Turks have succeeded one another with great rapidity, not to mention the numerous colonies of Armenians, Syrians and Gipsies planted in the heart of the Byzantine Empire by the foreign rulers on the throne of Byzantium. It would be a sheer miracle if anything of ancient times could have survived. Assuming even the theoretical possibility of such a miracle--and those who hold strongly to such a theory of unqualified survivals evidently do believe in such miracles--even then it will remain to be shown, with whom these ancient beliefs and tales originated and survived. The romantic legend may have, and practically has, been forgotten in its entirety. Out of one of the episodes have grown the popular Rumanian poems of the Wanderer.
If folk-lore is to become an exact science I venture to think that the problem of survivals will have to undergo a serious re-examination. We shall have to revise our views and try to define more precisely the method according to which we ought to label certain practices, customs and tales as survivals, and also to determine the period to which such survivals may be ascribed. A primary condition consists in establishing historical continuity and ethnical unity.
If nations of diverse origin and of different ages possess the same tales and practices, it follows that this common property cannot be a survival, but each must have received all these at a certain fixed date simultaneously, quite independent of their own ethnical or historical and local past. All of them must have been standing under one and the same levelling influence. This new influence may have brought with it some older elements belonging to different traditions and to a different past, and introduced them among these nations, as in the case of the Barlaam legend or that of the legend of St. George and the Dragon; but though locally accepted and assimilated they are not original constituent elements of the local folk-lore of these nations. These were only adopted and assimilated materials brought from elsewhere. They are not local survivals.
