Max Deutschbein sees a connection between the Bjarki story and the _Gesta Herwardi_ that would tend to establish the story in the _Bjarkarímur_ as earlier than the corresponding story in the _Hrólfssaga_.[25] H. Munro Chadwick, basing his opinion on the similarity between the career of Bjarki and that of Beowulf, thinks there is good reason for believing that Beowulf was the same person as Bothvar Bjarki.[26] Alois Brandl does not think that Beowulf and Bjarki were the same person. He calls attention to the difficulty involved in the fact, which, he says, Olrik has emphasized, that "Bjarki" is etymologically unrelated to "Biár"; and of troll fights, he says, there are many in Scandinavian literature.[27] William Witherle Lawrence thinks that "we may have to do with late influence of _Beowulf_ upon the _Hrólfssaga_".[28] He identifies "gylden hilt" with Gullinhjalti.[29] He regards the stories in the _Bjarkarímur_ of Bjarki's slaying the wolf and Hjalti's slaying the bear as earlier compositions than the story in the _Hrólfssaga_ of Bjarki's slaying the winged monster,[30] which, in agreement with Olrik, he regards as "a special late elaboration peculiar to the _Hrólfssaga_." He regards Saxo's story as earlier than the stories in the _Bjarkarímur_.[31] He refers to Mogk as believing that the Bjarki story in the saga is a werewolf myth into which the Grendel motive is woven.[32] He quotes a passage from Heusler, in which Heusler states that he regards the story in the _Bjarkarímur_ of the fight with the bear as earlier than the story in the saga of the fight with the winged monster and that, furthermore, Beowulf's fight with Grendel has been transferred to Bjarki.[33] Lawrence also calls attention to the fact that Gering thinks there is unmistakable similarity between the Grendel story and the story of Bjarki's fight with the winged monster.[34] Friedrich Panzer identifies Bjarki with Beowulf and regards the story in question in the _Hrólfssaga_ as a later composition than the corresponding stories in the _Bjarkarímur_, which he identifies with the Grendel story.[35] "Gylden hilt" he identifies with Gullinhjalti;[36] and Hott-Hjalti, whom Sarrazin regards as a personification of swords in _Beowulf_, he identifies with Hondscio, Beowulf's companion who is devoured by Grendel.[37] _The Story in the_ HRÓLFSSAGA _of Bjarki's Slaying the Winged Monster_. It appears to the writer that the key to the explanation of much that has been the subject of dispute, or has remained unexplained, in the story about Bothvar Bjarki in the _Hrólfssaga_ is the influence of the fictitious (in part, also historical) life of Siward, Earl of Northumberland under Canute the Great and succeeding kings. The life of Siward, briefly summarized from the _Dictionary of National Biography_,[38] is as follows.
