Peter Carroll was the first author I read who made magic magical and one of the few whose writings have repaid close repeated reading. Carroll is to be congratulated for writing this book and Mandrake for publishing it. The Apophenion is a gold mine of Carrollisms, and I could cite a score or more, even if few of the insights are original and some have been phrased more elegantly. That said, their power is undiminished and their application to magical working as timely as ever. No one with the slightest interest in magical theory should miss this book.
Much of the work is a description of Carrollian physics. I know barely enough physics to keep my tires inflated and not a whit more, so any attempt by me to evaluate "the maths" would be idiocy in its most literal sense. Indeed, I can barely even picture the simplest of Peter's demonstrations and I suspect I have a great deal of company. If you figure yourself among the numerically disabled, be warned. It may well be that Peter Carroll is the Giordano Bruno of our era and that he has demonstrated the elusive physics of magic, and if so, I am exuberantly pleased if ultimately quite unenlightened in spite of it. I'm just saying...
The artwork: first rate cover and the Muses (pg 112) are suitable for framing.
Two quibbles: either the proof reading of the book or the software used to compose it is deplorable. There are there are annoying repetitions of repetitions of words and the punctuation occasionally appears derived from an alien-as-in-not-of-this-world grammar.
