Gorgeous book in so many ways. Exquisite illustrations accompany detailed and learned descriptions together with the history and technical details of the book itself and its place in history. The selection is somewhat eclectic but there's no harm in that. The Berri Tres Riches Heures may be missing but there are plenty of other books on that.
Ordinarily I would find the author' personal odyssey irritating but he is sufficiently unassuming to make it acceptable and he is also an authority. They do become meetings between him and the manuscript.
Totally recommended.
