The epic songs, or bylínas, have been discovered in out-of-the-way places in the swampy region of the Government of Olónetsk. It has puzzled all the investigators to explain why the memory of Vladímir and his heroes should have lived so long in these distant regions when every recollection of them has entirely disappeared in Kíev, the scene of all their deeds. Throughout these epic songs there is evidence of their southern origin, yet nothing whatsoever is known of them in the south of Russia. Various explanations have been attempted, but the most wide-spread is that the Great-Russians of the south had been exterminated by the Tartars, and that the few who survived had taken refuge in the north, while the present inhabitants of the south have come from the south-east and represent a different tribe. There seems, however, to be a more plausible explanation. Considering that the _Word of Ígor’s Armament_ has not survived except in writing, and that there are no old epics living in the mouths of the people, except in inaccessible regions, it is natural to assume that no longer poem, nor a cycle of poems, which demanded a great amount of mental exertion and a special class of singers, could outlive the persecution of the Church, and that only where the people were separated from the rest of the world by impassable swamps and forests, and where, therefore, the influence of the Church was of necessity weakest, was it possible for the class of traditional bards to maintain itself. There is ample evidence that these epics were based on historical events, and that they belong to the same category as the historical songs, of which a number have been recorded from the seventeenth century and later. The oldest are those that Richard James had written down in 1619; they were composed by some popular bard immediately after the incidents which they relate. Later historical songs deal with Peter the Great, while the song collections contain many others that range in time from Iván the Terrible to the nineteenth century. The manner of all these is identical, and strongly reminds us of the epic songs. From this it may be inferred that the bylínas were separate songs, composed by contemporary bards, and that their present condition is merely due to that series of corruptions to which all orally transmitted literature is subject.
