So, now instead of comparing Beowulf to a terrible movie that was only very loosely based off the epic poem Beowulf, I am getting to do something more fun and instead be comparing it to another Epic Poem of great stature from the Greeks, The Lliad. But we're not going to be comparing the stories to each other. Instead we are comparing the heroes of each to one another in terms of epic hero levels, Beowulf versus Achilles. Who will win, I have no idea at this point, so you'll need to read to find out.
The first thing we will focus on is there mental fortitude, now in my opinion, they both fail in this department in different ways. Achilles shows himself to place his feeling above his rational actions, which as he states, almost led him to killing the king. Now Beowulf also has a problem with rationality in that he always believes that fate decides the battle and not himself which I believe turns into a self fulfilling prophecy at the end when he does die as he believes fate is against him in battle and almost gave up morale wise admitting that. So in other words, both of what one could call their biggest flaws could be seen in their emotionality and not physicality.
Since the first was a draw, it looks as if we will have to bring it to the next area of debate. Who is physically better. Now this one is also a very easy one as Beowulf still shows the ability to basically breathe underwater and pick up usually unusable objects as weapons as he picked up the sword to slay Grendel's mother, not to mention he beat a demon to death with his bare hands. Whereas Achilles only has the killing of a prince as a major accomplishment. So the choice of winner is obvious in this case.
So as I feel the word limit closing in on me, I will end with that brief overview in which Beowulf has come out as the better epic hero, however, The Lliad will always be known as much more useful in the development of western literature into its modern form.
