Matthews does a wonderful job of pulling together different treatises throughout history on how the world has and does view Druidism. This is a very dry read, but is filled with great information.
I read a review where an individual stated that "this work was outdated'. Well the ancient druids certainly 'are' and here is a good collection of their history! It seems the more and more I read reviews of Matthews work I come across the complaint that its "dry history'. While this may be true there are also gems within the desert if one cares to look. Also all the books that I've ever read about "druid magic, techniques, shamanism etc...I have found to be worthless and just a dressed up version of wicca. The Encyclopedia of Celtic Wisdom is another example of fine writing and research. Once again we must remember this was"an oral tradition".
