So, not even worth opening up at all then? Not quite. Some of the detail is interesting for its own sake. The biographical detail and character study of the artist is enough to reawaken my interest in the man behind the legend. The description of the heresy - which did exist, although it is unlikely that Leonardo was part of it - and the impact it could have had on the Church of Rome is well described. The treatises on art and religious symbolism are also edifying for those of us with limited knowledge of such things. I did learn a thing or two... I just found it a little heavy going to get there.
Clearly the book invites comparisons with [[Dan Brown]]'s work, but your reviewer confesses to not having read [[''The Da Vinci Code]] '' so is unable to comment.
On the other hand - the little known work [[Montaillou]], by Emmanuel LeRoy Ladurie, is worth reading if you're intrigued by any of the ideas raised by the story.
