Fabulous poetry - both the original (quite a lot is understandable when read next to the translation) and the new verse translation. However the subject matter is not terribly interesting..... basically it is a propaganda exercise at a time when the English had been gradually losing control of the vast lands of Western France. King Arthur is repeatedly described as entitled to rule the Roman Empire as 'did all his ancestors except Uther'.
I really, really tried, got over half way through but despite the power of the verse the subject is just too dull. Lists of rich people killing or being killed in various different ways. I skipped over the rest of the book to see if there was any plot or any interest in his homecoming but it was just more of the same.
