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
