This book assembles a great deal of evidence for religious practices in Britain, but despite some genuine insights (for example in relating religious sites to natural features and phenomena, and a highly commendable use of ancient sources), in general it is superficial and lacks real empathy with ancient cult. The gruff, colloquial writing style proclaims that this is a plain man's guide' and presumably the avoidance of meaningful engagement with iconography, iconology, art or theology, goes along with this, though for me these are all vital for any understanding of ancient religion. Other books by the author show he can do far better and, indeed, Gods with Thunderbolts betrays signs of a very hasty composition, and reads more like a first draft than a finished product.
