Foreshadowing in Beowulf

Foreshadowing Examples in Beowulf:

III 1

"hence it after became           Certainly known to the children of men..."   (III)

For the purposes of the story, it is important that Grendel's reign of terror lasts as long as it does. By stating that the dire situation became well-known among the Danes, Swedes, and Geats, the poet foreshadows the coming of a hero to save Hrothgar's Hall.
