This is a mammoth book, at over 600 packed pages. What sets it apart from any other of it's type is that Will has formed a synthesis of the mythic material with it's sources with interpretations, added to this he has placed the whole mabinogi within the context of prehistory and medieval history and politics. This effectively means that the mabinogi is studied in the context of the people with which it arose, evolved and developed with prior to its eventual committal to parchment.
Last night I read through the second chapter concerning the first branch. This book is stunning. He has taken the individual branches and clothed them in a colourful series of leaves, twigs and buds. his means of treating the mabinogi is astounding, the work that must have gone into this book defies comprehension. It is going to take me a while to read the book in all, especially with work at the moment. however, I cannot wait to get more reading in. Once done I think I will start all over again but make notes also. This is a bittersweet time - I have in front of me a wonderful work which I want to devour and read from cover to cover, however I also want to absorb it fully. I cannot do both at once which is terribly frustrating. Patience.
HIGHLY recommended. I suggest buying it straight from the author via his website.
