Translation, you say. Um. I've never looked at a translation, myself. There's what seems to be a half-decent translation of the long form of the Sermo, based on Bethurum's edition (Bethurum printed three separate versions of the SL, as opposed to Whitelock, who put 'em all together in a mash). It's in the back of Roy Luizza's translation of Beowulf, which is published by Broadview Literary Texts.
