The book is an absolute kitchen sink of onomastic conjectures, numerological hypotheses, and strained mythological derivations, all precariously balanced upon the author's idiosyncratic emanationist ontology. While this material makes for interesting speculation, and in some instances may even hint at valid interpretations, the lack of an index makes locating any of it for research purposes onerous to the point of uselessness. Perhaps one redeeming element (especially, and indeed only, for practitioners) is the author's discussion of the astrological aspects and conditions that may be particularly conducive to working with each spirit—if one has the patience to look page-by-page for the daemon in question—based upon consonances with the offices and functions they have been traditionally ascribed. That being said, anything of use here is already available in a more accessible form in any number of more focused publications. Cannot recommend.
