In "Guide to imagery series" books I found the books on art
that give an exceptionally clear presentation of the subject.
I bought 6 books ("Nature and Its Symbols" among them)
and I really found what I was searching for. You can study Old and
New Testament as well as ancient mythology reading these books,
understand the role of different details, symbols drawn on each picture. Inside each book there is a short description of the specific topic followed by full-colour reproductions of the pictures on this topic from different museums all over the world with detailed explanations to each picture. It was amazing to find and understand the meaning of different pictures I saw in art galleries in St.Petersburg, Berlin, Munich, Dresden, Venice, Naples and other places. Really a great selection of art works is presented in each of these books. I strongly recommend all these books to everybody who wants to understand the meaning of the pictures and get a nice art collection at home.
