Nature and It's Symbols is about symbols, art, animals and its meanings. It talks about various plants and flowers; lilies and tulips being my favorite. It talk's about fruits, animals such as the bats and the spiders and wolves which I find the most interesting, Flying Animals, and my favorite section: Creatures Of Imagination and my favorite creature was the Griffin probably because I saw the movie Spiderwick Chronicles way too many times as a child.
The paintings are a bit Christian/religious orientated so if you are looking for anything else, you might not find any interest here, but I found it interesting. It is a well organized books, the third half kind of bored me a bit but it was overall pretty good. Would highly recommend, and you don't have to read this book in order.
It also referred back to Ovid, one of my favorite poets next to Dante, Milton, and Bukowski.
