Beowulf

This is a great story and Seamus Heaney does a masterful translation. What is especially nice is the translation on one page and the original Old English on the other, complete with copious footnotes and definitions of arcane terms.

Even if you don't like Beowulf this is a fantastic book to have for learning Old English. Then again, I don't think I've met anyone learning OE that didn't like Beowulf...

And if you've never read Beowulf, but are interested, this is the edition to get. I can assure you it is much, much better than the movie.
