A web page with many interpretations of Beowulf (the person) and Beowulf (the book): http://www.public.asu.edu/~atrja/beowulf.html
It's short, but full of material to think about.
While doing a little more web surfing, I found the content of this blog had been uploaded on a web site called Scribd. It's a compliment that someone wanted to put up a mirror, but annoying that he or she didn't ask me, or even leave me a comment. I've requested Scribd to take down my work.
