5. In discussing the genealogy of the Danish kings in _Beowulf_ and comparing it with that of other documents,[186] it is to be remembered that the _Skjọldungasaga_ has no independent value as an authority in this connection; its value lies in its recognition of a conflict between the Ingjald lay and the story in the _Hrólfssaga_, and its attempt to harmonize the two. 6. On the whole, as Olrik says, "Hvor værdifuld den islandske _Skjọldungasaga_ end er, den er selvfölgelig ikke på alle punkter at foretrække for enhver anden kilde."[187] When it disagrees with other documents, its statements should be scanned with care. A little ought to be said about Saxo's treatment of the problem, the solution of which in the _Skjọldungasaga_ has just been considered. The solution in the saga is based on the recognition of the fact that Frothi as a king who was slain (i.e., by Swerting) and later avenged by his son is irreconcilable with the idea that he slew his brother, whose sons later put Frothi to death and thus avenged their father's murder. Saxo solved the problem by employing two Frothi's,--namely Frothi IV, Ingjald's father, who was slain by Swerting and was avenged by his son, and Frothi V, Ingjald's successor, who slew his brother, Harald (i.e., Halfdan in the _Hrólfssaga_), and later was put to death by Harald's sons. On the whole, Saxo's story presents something of an attempt to harmonize Danish and Old Norse tradition. The Danish tradition about the Hroar-Helgi group of kings Saxo preserves in his second book. The Old Norse tradition about them he utilizes in his seventh book, at a point where, in the line of Danish kings, it occurs according to the Old Norse conception of the matter.[188] In the latter connection he repeats certain features of the story as it appears in his second book. Ingjald who appears in the sixth book is really the same Ingjald (second book) whose son Agnar is slain by Bjarki; and Helgi (here called Halfdan) takes to sea, just as he does in the second book. All that concerns Hrolf Kraki, Yrsa, Bjarki, etc., Saxo omits from the seventh book; but he gives Halfdan (Helgi) a career in Sweden, something like Helgi's (second book). Halfdan dies, however, without leaving an heir to the Danish throne; and this solves another problem, for thus the necessity of introducing Hrolf Kraki, Helgi's son, again, or some substitute for him, is obviated, and the story of this royal family is brought to an end. _Conclusion._
