They are extremely scholarly and evenhanded (if a bias is detectable, it is against the French) and written in the wonderful style of an Oxbridge don: "The brief reign of Duke Godfrey saw the beginnings of a Christian kingdom. But Godfrey, for all his estimable qualities, was a weak, foolish man. Out of jealousy he quarrelled with his colleagues; out of genuine piety he yielded far too much power into the hands of the Church."
I cannot recommend his work more highly.
Anyone that uses the word 'estimable' is fine by me. Thanks for the info.
Thanks for the recommendation. After all this discussion, I want to educate myself on this subject.
