Six months. And do you know how fast parchment burns? Excuse me, I am going to go cry now.
If you get the chance read the book "Treasure" by Clive Cussler. It's a book about the library director smuggeling most of the books and artworks out and hiding them before the library was destroyed. The story is about it's discovery 2000 years later in an unlikely place.It's an action adventure book with other subplots to it.It's a great read!
