Interesting and informative, though not quite what I expected. Based on the somewhat misleading subtitle "a universal language", I suppose I was expecting something a little more technical and abstract regarding the nature of symbols, how and why we use them, history and philosophy of symbolism across geography and culture, and so on in that vein. There wasn't really much of that at all in this book; there was a short pre-history section, but after that it became more of an encyclopedia of specific, selected symbols, consisting mostly of of anecdotes and trivia, presenting a selected symbol and giving its meaning and history in brief 2-3 page summaries. I might go so far as to recommend it as a "bathroom reader" book, due to the way the book is organized by symbol; yet the writing style was straightforward, easy word choice and sentence structure, very easy to skim, so I was able to read through the whole book in a couple of hours just as well.
Basically, I was a bit disappointed because the subject matter was much more simplistic and limited than I had expected; however, taken for what it is, it was not uninteresting, and I learned some new bits of trivia I had never heard of before. I wouldn't bend over backwards to go out and find it, but if it happens to cross your path, its not a bad read.
