Examine what Beowulf says to Hrothgar about himself and his past deeds. Why does he appear to boast about his accomplishments?

Beowulf is passing down the stories of the legacy he will leave behind. Storytelling was a way to protect and pass down history, particularly before written word. The story of Beowulf's courage and achievements would have been told over and over again.... until finally, someone wrote the first manuscript.... the epic of Beowulf.
