To preface, my credentials as a reviewer of historical or literary scholarship are nought. I am a layman with an interest in medieval and religious history. This book was, however, fascinating and I ripped through it.
I disagree that it is stuffy in parts, I believe the style, depth and indeed pace is apt for the subject and nature of the material, but written in way that is perfectly accessible for a non-scholarly audience, unlike many books published by routledge.
The themes are, as a previous reviewer described, revelatory, and where the author saw reason to question the accuracy of her interpretations, has pointed this out. This seems appropriate given the very original and provocative nature of the scholarship, and as such lent an added air of credibility.
Overall I was thrilled with this book and throughout was imbued with confidence that the authors reading of history was both unbiased and well considered. I would recommend highly to anyone with an interest in history of the occult or renaissance era Christianity, but certainly not for those who wish to explore the occult itself in any depth, for this book neither is nor pertains to be about that.
