This book is more of an overview of several books than focused on one in particular, but still nice for the plates and a good sampler if you're not sure what to get. The title of this book is not misleading if you know anything about the history of Celtic art and it's later years in illumination, from my experience as a reviewer for the British Museum's publications and having worked in Ireland on archaeology digs as their sketch artist. ;-) During the Christian era of Celtic art they did have many influences of Coptic, Greek, Norse, *and* Persian design, especially in the Book of Kells. The Irish monks did quite a lot of travel during the dark ages to promote learning, and the monastaries in Ireland had students from countries all over the world, hence a good influx of other ideas which they of course fused into their own (masters of adaptation!). "The Old Philosopher"'s desire for Ogham to be used in the manuscripts is very far off... the latin uncial used in the manuscripts is standard for the period, as the ancients Celts (pre-Christianity) didn't have books per sae, only a sort of "runic" writing system of slashes used on staves and stone. They *had* no manuscripts so expecting to see Ogham in a manuscipt would be ridiculous! I think "The Old Philosopher" misunderstands the period of Celtic history these books were created in, as the title is certainly reflective for the period listed. If you enjoy Celtic manuscripts such as the Book of Kells or Lindisfarne Gospels this will be a nice overview of some of the different evolutionary flavors the artwork went through. If you want more information on Celtic art then any book by Ruth and Vincent Megaw (such as "Celtic Art", available from Amazon as well) will cover the early periods (typically only up to the Christian era, or briefly entering the Christian era), and then any book published on the old manuscritps such as the Book of Durrow, Lindisfarne Gospels, and the Book of Kells are great. This book is more an overview of a bunch of books, so good for starting out your manuscript collection.
