I was fortunate enough to be in the audience for two of the lectures where Robert Bartlett presented some of the initial drafts of the work that would become Blood Royal. In particular, his discussion of the use of regnal numbering in medieval Europe, from its origins in the papacy to its later adoption by various monarchies, was one of the most interesting talks I’ve ever attended. I’d been looking forward to this book ever since it was implied at the final talk that one would be forthcoming, and while I had to wait quite a while the final product did not disappoint.
