Some of these verbal resemblances may be granted as proved: but they surely do not prove the common origin of the two dragon fights. They only tend to prove the common origin of the school of poetry in which these two dragon fights were told. That dragons dwelt in mounds was a common Germanic belief, to which the Cottonian Gnomic verses testify. Naturally, therefore, Frotho's dragon is montis possessor: Beowulf's is beorges hyrde. The two phrases undoubtedly point back to a similar gradus, to a similar traditional stock phraseology, and to similar beliefs: that is all. As well argue that two kings must be identical, because each is called folces hyrde.
These commonplace phrases and commonplace features are surely quite insufficient to prove that the stories are identical—at most they only prove that they bear the impress of one and the same poetical school. If a parallel is to carry weight there must be something individual about it, as there is, for example, about the arguments by which the identity of Beowulf and Bjarki have been supported. That a hero comes from
Geatland (Gautland) to the court where Hrothulf (Rolf) is abiding; that the same hero subsequently is instrumental in helping Eadgils (Athils) against Onela (Ali)—here we have something tangible. But when two heroes, engaged upon slaying a dragon, are each told to be brave, the parallel is too general to be a parallel at all. "There is a river in Macedon: and there is also moreover a river at Monmouth, and there is salmons in both."
And there is a fundamental difference, which would serve to neutralize the parallels, even did they appear much less accidental than they do.
Dragon fights may be classified into several types: two stand out prominently. There is the story in which the young hero begins his career by slaying a dragon or monster and winning, it may be a hoard of gold, it may be a bride. This is the type of story found, for instance, in the tales of Sigurd, or Perseus, or St George. On the other hand there is the hero who, at the end of his career, seeks to ward off evil from himself and his people. He slays the monster, but is himself slain by it. The great example of this type is the god Thor, who in the last fight of the gods slays the Dragon, but dies when he has reeled back nine paces from the "baleful serpent[[222]]."
Now the story of the victorious young Frotho is of the one type: that of the aged Beowulf is of the other. And this difference is essential, fundamental, dominating the whole situation in each case: giving its cheerful and aggressive tone to the story of Frotho, giving the elegiac and pathetic note which runs through the whole of the last portion of Beowulf[[223]]. It is no mere detail which could be added or subtracted by a narrator without altering the essence of the story.
In face of this we must pronounce the two stories essentially and originally distinct. If, nevertheless, there were a large number of striking and specific similarities, we should have to allow that, though originally distinct, the one dragon story had influenced the other in detail. For, whilst each poet who retold the tale would make alterations in detail, and might
import such detail from one dragon story into another, what we know of the method of the ancient story tellers does not allow us to assume that a poet would have altered the whole drift of a story, either by changing the last death-struggle of an aged, childless prince into the victorious feat of a young hero, or by the reverse process.
Those, therefore, who hold the parallels quoted above to be convincing, may believe that one dragon story has influenced another, originally distinct[[224]]. To me, it does not appear that even this necessarily follows from the evidence.
It seems very doubtful whether any of the parallels drawn by Sievers between the stories of Lotherus and Heremod[[225]], Skioldus and Scyld, Frotho and Beowulf, are more than the resemblances inevitable in poetry which, like the Old Danish and the Old English, still retains so many traces of the common Germanic frame in which it was moulded.
