forskellig art; de danske giver os de æventyragtige elementer, hvoraf sagnet opstår. Den islandske Hrólfssaga og Bjarkarímur viser os dets videre udvikling til æventyrsaga. Selve den nordengelske Sivardssaga står i midten som et mærkeligt mellemled i udviklingen".[43] Here we have the first indication of contact between the Siward saga and the story of Bjarki, in the Hrólfssaga.

There is much in the main features of the lives of Siward and Bjarki that is similar. Both were men of extraordinary prowess and bravery; both gave up a great heritage at home (Siward, an earldom; Bjarki, a kingdom); both left their native land to enter the service of a foreign monarch (Siward entering the service of Edward the Confessor; Bjarki, that of Hrolf Kraki); both slew a ferocious monster; both paused in another land (Siward, on the Orkney Islands; Bjarki, in Sweden) before reaching what was to be their destination; both displayed their warlike qualities by slaying a man of great prominence who was closely connected with the king (Siward slaying Tosti, and Bjarki slaying Agnar); both were the king's chief support in his wars against his enemies; and both invaded a foreign land (Siward making an expedition to Scotland, and Bjarki accompanying Hrolf on his expedition to Sweden).

Certain features of the life of Bjarki mentioned above, such as his bravery, strength, his being in the service of Hrolf Kraki, his killing a fierce beast, and slaying Agnar, the saga-man found ready to his hand; but not the renunciation of his kingdom. Earldoms and kingdoms are not renounced "for light and transient causes." As regards Siward, who renounced his earldom, he seemed to be destined for a greater career, as subsequent events show and as is indicated by the fact that Odin (for the old man on the hill whom Siward met was none other than Odin) took a hand in directing his course. But when Bjarki renounced his kingdom, it was altogether unmotivated. The saga says: "Soon afterwards [i.e., after Bjarki's revenge on his evil stepmother] King Hring fell sick and died, whereupon Bothvar succeeded to the throne and was for a time satisfied. Later, he called his subjects together to a 'þing' [i.e., assembly] and said he wished to leave the country, married his mother to a man named Valsleit, who had been an earl, celebrated their wedding, and departed".[44] He became Hrolf's most noted warrior, but neither sought nor attained to any other distinction. The renunciation of a kingdom for the fate of a man who appears among strangers and gets what his own right arm can win for him is a rare occurrence; and when the saga-man lets Bjarki become a king and then, without reason, renounce this highest of all earthly dignities, it can only be in servile imitation of the corresponding feature of the Siward saga.

Besides those already mentioned, the two stories have other features in common. It is said of Siward, that when he learned that his son Osbeorn had fallen in battle, he became so angry that he sank his sword into a rock. It is said of Elgfrothi, Bjarki's brother, that he swung his sword against a rock with such force that it sank in to the hilt. But Elgfrothi's feat was performed under such widely different circumstances that the author may, or may not, have had Siward's feat in mind in recording the incident. However, suggestions received from one story are often employed in another quite as the author sees fit, so that, although one is not inclined to attach much importance to this incident, it is, nevertheless, worth noting.

Somewhat more noteworthy than the incident just mentioned is the introduction of Odin in both stories in the disguise of an old man. In the Siward story he appears on a hill as Siward reaches Northumberland on his journey from the Orkney Islands, and tells Siward what course to pursue, presents him the banner Ravenlandeye, which is accepted, and predicts for him a brilliant future. In the Hrólfssaga Odin appears as a one-eyed old man living in a hut in Sweden. Hrolf and his men seek a night's entertainment of him while on their way to the Swedish court, and the old man tests their endurance and instructs Hrolf in regard to the measures he must take to accomplish his purpose. Odin also appears to the men as they return on their way to Denmark, when he offers Hrolf a sword, shield, and armor. Hrolf declines the preferred gift, whereupon Odin tells Hrolf that he is not as wise as he thinks he is, and Hrolf soon, but too late, realizes that the rejection of the gift augurs ill fortune. There is nothing unusual in the appearance of Odin as a one-eyed old man, for it is a common characteristic of saga literature. But though Hrolf's expedition to Sweden is mentioned in Snorri's Edda,[45] where the passage concerned is based on the old Skjọldumgasaga, the oldest authority in regard to the matter, but unfortunately now lost, no mention of Odin is made in this connection.[46] Furthermore, Odin again appears in the saga (at the close), where Bjarki vows that if he could get his eye on the god he would use him roughly for permitting the enemy to gain the victory in the battle that is being fought and that is going against Hrolf and his men. In the latter instance, Odin belongs originally to the story (Gest. Dan., second book, where Odin is represented as riding his steed Sleipnir and being invisibly present at the battle to take the dead to Valhalla). The two conceptions of Odin—on the one hand as appearing in the disguise of an old man; on the other, as riding his horse, Sleipnir, and taking those fallen in battle to Valhalla—are quite different, the former being distinctly Norwegian, one of the circumstances that Olrik uses to show that the Siward saga originated under strong Norwegian influence, while the latter was the conception of Odin current in Denmark and Sweden.[47] As already stated the introduction of Odin as an old man is a motive that occurs frequently in saga literature. It cannot, therefore, be stated definitely that his appearance in the Siward saga suggested the use of him in the Bjarki story. But the two stories were current in the same locality; they were formed under similar conceptions of saga literature; in both stories Odin directs the hero in question as to the most advisable course to pursue and offers him a present; the Bjarki story already contained an instance, of another mintage, of the Odin motive; as stated above, the oldest authority in regard to the matter says nothing about Odin's appearing to Hrolf on the expedition to Sweden; and, as we know, the one has acquired important features (Bjarki's bear-ancestry and his renunciation of his kingdom) from the other. These circumstances render it highly probable that this is another of the Bjarki story's acquisitions from contact with the Siward saga. Incidents of this kind need not necessarily be used in one story as they are in another; saga literature abounds in evidence of this fact, as, for instance, Saxo's and the Hrólfssaga's story of Hroar and Helgi, considered later.

A feature of the Hrólfssaga that is much more noteworthy in this connection and that has certainly been acquired from the Siward saga is that concerning the kind of monster slain by Bjarki at the court of Hrolf Kraki. When Siward's bear-ancestry had been transferred to Bothvar Bjarki, it followed as a matter of course that Bjarki must no longer be represented as killing a bear. Siward had driven a dragon, which had killed men and cattle in great numbers, from one of the Orkney Islands; and it is in imitation of this exploit that Bjarki is represented as having slain a winged monster (dragon). This would be only another instance, in addition to those already mentioned, of the influence exerted by the story of Siward on the Hrólfssaga. Ordinarily, there was nothing about Bjarki's person that revealed or suggested that his father was a bear; but he was able to assume the shape of a bear, which, according to the Hrólfssaga, he
