I bought this a very long time ago thinking it was a handbook of natural magic, but was surprised to find that it was actually a very interesting piece about various themes within witchcraft.
The title is a little bit of a misnomer seeing as it's actually describing magic itself as 'natural' rather than the book being about it specifically. However, 'Natural Magic' does go into a variety of what one would deem 'natural magic' topics, but Ms Valiente does so in a more mythological/historical context than a practical one. This is no bad thing; in fact I think this makes the book far more useful than any handbook could be! Importantly, Valiente expounds clearly and efficiently information of interest whilst leaving room for further study.
I particularly enjoyed the discussion of divination via playing cards a la the cunning folk -- she gives some instructions on how to read them from an older source. I also loved the bits on numerology where Valiente provides one with a reference on how to figure out ones lucky number. The engravings and illustrations also lend the piece a very arcane feel.
The topics covered within the book are many, and Valiente often goes off onto related topics under one uniform heading i.e. in the chapter titled `magic of birds and animals' she talks not only about animals but horned gods (Pan, for example) and his role in the wild woods etc.
The contents consists of: magic of the mind, magic of the four elements, magic of herbs and flowers, magic of numbers, magic of colours, magic of talismans and amulets, magic of sex, magic of dreams, magic of the weather, magic of the cards, magic of birds and animals and traditional spells.
Highly recommend for all Witches and Pagans.
