"The Celtic Book of Days" By Caitlin Matthews is more of a book of daily factoids than a spirituality and wisdom book. Once this fact is realized you can enjoy reading on a daily basis and seeing if you know that fact or not. If not then you have the fun of finding out more. Once in a while the snippet reads more like a Chinese fortune cookie.
Besides being split up in to daily snippets there is an over all calendar to keep you informed of the seasons, a decent bibliography, and index. This makes a great coffee table conversation book.
Contrary to the first reviewers opinion (Nov. 18, 1999), this book is not a devotional text. I think this person has gotten this text confused with "The Celtic Spirit", a devotional text by the same author.
As for the "Celtic Book of Days" it is a well laid out calendar. Not quite what I expected, it seems to be lacking depth, and some days don't have very much information or artwork at all. I truly expected more.
If you wish to use it as a tabletop calendar, why not? That's what I use if for, but as a study tool there really isn't much there, which is fine as well. The passages mainly consist of brief poems or sayings, quick history reviews of ideas and significance of days. As I said earlier... not what I expected, but not a total disappointment either.
Not much more then a starter conversational piece IMHO.
