Unferth accuses Beowulf of "wantonly tempting the waves" and risking his life for a "silly boast." Given what Beowulf and the narrator say about Unferth, how is Unferth's comment a reflection back on himself? How does it apply when we think about Grendel? Consider Hrothgar's comments on his men (lines 363-371). Why is it important for him to disparage on Beowulf's actions as being foolhardy?

Let us know your thoughts; then someone here will be able to help you.

I needed help tying the first question into the second one--like how does the fact that Unferth is jealous of Beowulf apply when thinking about Grendel?

Did you notice this brief description in the third link above?

"Unferth -- rude, unpopular drunkard with a rotten boil; believer in Grendel"

Does Unferth want Beowulf to succeed? Why or why not? How do people often behave when the DON'T want certain other people to succeed in whatever they've set out to do?

No because he doesnt want anyone else to be more famous/glorious than him. Rude and they try to put you down/make you feel like you will not be able to do it

Apply all those ideas to answering your original questions! Good for you!!

I still don't understand how that applies when thinking about Grendel...

What does "believer in Grendel" mean to you in that description of Unferth?

That he believes in Grendel

... and he doesn't want Beowulf to go after Grendel. He doesn't want Beowulf to win!

ohh. i also didn't catch what Hrothgar's comments on his men were. and does "him" in the last sentence refer to Hrothgar or Unferth?
