Although I had bumbled my own way to the conclusions reached in the previous article about the context for Æthelberht's Laws, Patrick Wormald had already reached them (or ones very similar) 20 years ago. See The Making of English Law round about p.100. This will go into a footnote, as will an acknowledgement to Dr Levi Roach for putting me onto it, though I really should have known to look there to start off with if I was any good... What I will make of this point, however, is likely to be rather different from what Wormald did.
