I bought this book when it was first published, in spite of its high cost, because Robert Hand was enthusiastic about it at the time. It is rather a hodgepodge of mainly neoplatonic philosophy attached to Damiani's interesting, but idiosyncratic, theories about astrology and emanation. I was not favorably impressed by the astrological content of the book, and in any case new translations of source texts have supplanted it (in terms of Hellenistic astrological theory and practice, at any rate). I wonder what Hand would say about the book now.
It's quite a beautiful volume, filled with photographs, illustrations and notes by Damiani. It is not, in my estimation, a reliable guide to Hellenistic astrology per se, especially now that Robert Schmidt, Chris Brennan and Ben Dykes have opened wide those doors. But it does offer philosophical discussion and speculation keyed to astrology as a science of the spheres.
