I don't know if this surface explanation works or not, but I hope that it helps some. I had the opportunity to work with Bob Yeager for my 6 week fellowship. He is at the University of North Carolina at Asheville. He is considered one of the world's great authorities on Beowulf and one of only a handful of people who have been allowed to actually use and study the original text. He is an amazing source of information and to learn from him was an unbelievable treat. Beowulf is one of those works for which I have a tremendous appreciation and love and I enjoy teaching it. When I took a group of students to London each of the last two years, the one thing my students had to see was the original text. They were completely mesmerized by it (and also amazed at how small the text actually is). I guess my appreciation transferred to the students. I hope that it does here as well.
