Mr. Cornwell, First I would like to say I am a great fan of your work, especially the Warlord Chronicles. Currently, I am working on a graduate degree in Literature and this semester I am in a study of Arthurian literature. One topic that fascinates me is the “trial by combat” idea that you present in the duel between Owain and Arthur. I was wondering if you had a particular source (or sources) that link Owain to this type of battle, other than Chretien, a source which positively links Yvain/Owain to similar duels. Thanks! – Ben
