This story, namely that the man whose cattle have been killed by a bear goes with his men and hunts it down and kills it, is the same that we have in connection with the early life both of Ulf and of Bjarki, where the bear is represented as being the great-grandfather of the former, but the father of the latter. The bear-ancestor feature was not applicable in the connection in which the story is used in the _rímur_; hence, it was omitted. Now, did this story spring up spontaneously and independently in all these three instances? No, Bjarki and Ulf got their reputed ancestry from the Siward story; and this bear hunt story they got from a common source through contact with each other, or Bjarki got it from Ulf. The author of the _rímur_, liking it better than the last part of the dragon story in the saga, as most modern readers also have done, took it from the version contained in the saga of the early life of Bjarki and used it for letting Hjalti display his courage. As a result, he modified the story where it applies to the early life of Bjarki. He has two sets of three sons each, while the saga has only one set; and, what is still more suspicious, there is a Bothvar in each set. This is the same kind of separation or repetition as the _rímur_ later make with regard to the dragon story, dividing it into a wolf story and a bear story. Again, as Finnur Jónsson, summarizing the account in the _rímur_ of the death of Bjarki's father, says, "Björn forfölges, flygter ud i et skær og dræbes der af jarlens mænd på et skib (en stærk afvigelse fra sagaen)."[119] This divergence was plainly introduced to make the story different from the story that, in substance, was replaced and that was transferred to where Hjalti displays his courage. In the saga, Bjarki's mother is called Bera (she-bear),[120] not Hildr, as in the _rímur_; and that the name Bera is the earlier of the two there can be no doubt.
