I belong to a Celt cult since 1972.
When I read the book I found a very well documented work on our beliefs and practices.
It even helped me understand some things that I didnt comprehend.
The text is dreadful, but what can you expect from a book that was written some 200 years ago! There have been a lot of advances in Celtic archaeology since then. But the illustrations which are old steel engravings of the megalithic sites are absolutely worth the price.
