Since the beginning of my interest in ancient history and culture I have been held by an inexplicable fascination with all things Celtic. At least, what I perceived as Celtic from my admittedly untrained eye. Nora Chadwick's volume "The Celts" has only served to further my interest in their long history, varied culture, and supernatural worldview as expressed through their art, literature, and religion.
At the start of reading this volume I had only previously read T.W. Rollerston's "Celtic Myths and Legends", and R.J. Stewart's dual volume "Celtic Myths, Celtic Legends" and "Celtic Gods, Celtic Goddesses", so I didn't have a firm footing for the archaeological history of the Celtic peoples. The first 4 chapters (100 pages) cover nothing but that, tracing the nomadic Celtic tribes of Iron Age Europe, up through the refined Medieval Welsh society. I was completely unprepared for the language of the Celts, which Chadwick maintains to a fair degrees. After a brief online crash course in pronouncing names properly (something I need in order to feel comfortable while reading) I hit the book hard.
After those first hundred pages things settled down for me some. The historical element had been covered. I had learned about the Hallstatt period, the La Tene period, the insular nature of Ireland, the constant struggle between the Picts, the Scots, the Romans and everyone else in Great Britain, and so on, and so forth. It was all very interesting, as many of my previously held notions were finally set straight, including the fact that Celtic peoples are as old, if not older, in Europe than those of Greece and the Etruscan nation, and that written language (Ogham that so many modern Druids use) was not an early invention, and may have been in relation to the Norse/Viking raiders who brought their Runic characters with them. All things considered, a very interesting overview, especially since it was only a third of the book.
The final five chapters (and 200 pages) were what I was really interested in. Chadwick beautifully outlines the various influences from Rome and the Viking raiders that influenced mainland and island Celts, and traces in very plain terms the development of Celtic religion from animistic natural worship of the land and it's features, to a centralized pantheon of recurring characters, to the influence of Saints and Christianity, concluding with Ireland's refusal to give up her pagan beliefs, instead creating a blended faith of Irish paganism and Roman Catholic monotheism that resisted refinement for several hundred years.
I was also impressed by Chadwick's study of Celtic architecture, art, and literature. All three of which were topics I was only vaguely familiar with. I felt that in all three instances she provides a very sturdy foundation, which those interested can use as a springboard should they desire to know more about each individual topic.
That, in fact, brings me to the only warning I have concerning the volume. I went in with a lot of preconceived notions about the Celts and their way of life. Chadwick's volume wonderfully educated me concerning them. I, however, was new to Celtic culture. If you're different from me, and already have a firm grasp on the Celts, their traditions, their history, and way of life, then this volume will probably not enlighten you any further. Chadwick, by the nature of her undertaking, had need to only touch on each topic briefly, so as not to create a tome of unimaginable weight that would be unreadable.
If you're new to Celtic themes and ideologies, begin with this book. If you're already firmly established with their history and culture, then seek a writer with a more centralized focus, it will be significantly more appealing to you and your particular interests.
