This little book packs a punch. Not even 100 pages and nicely illustrated, it still manages to be a nice, concise introduction to the belief system of the pre-Christian Celts. Of course, the brevity may owe something to how little we know with any certainty. Phrases like ‘there’s no direct archaeological evidence of…’ or ‘we can’t be certain that…’ appear with distressing regularity in any book about the Celts. It’s an inescapable problem. But if you’re looking for an entry point, there are worse places to start and not many better.
