post, advertisements for the film Gods Of Egypt proclaim that "The Battle for Eternity begins!" A Battle for Eternity! What can possibly follow that?
I have reread Poul Anderson's Hrolf Kraki's Saga to the point where it suddenly hits us that the Hroar whom I have been praising is that king whose splendid hall was terrorized by the monster Grendel who was then killed by the hero Beowulf. However, I find that I have posted on this "Unexpected Crossover" before.
Beowulf is Hroar's brother-in-law, the son of that father-in-law, Aegthjof, whom Hroar had helped. See here. Thus, when Aegthjof says:
"'I hope I or child of mine may someday do the like for you.'" (Hrolf Kraki's Saga, p. 59) -
- this hope prefigures the story of Beowulf. Helgi is away, therefore cannot deal with Grendel, but "...Bjovulf of Gotaland, the man that in England they call Beowulf..." (p. 65) comes instead. Beowulf is summarized on pp. 65-66.
