When I did this little polychrome terracotta, around 1994, I was creating many artworks using the shape of books, and real books. Books were meaningfull symbols for me - and they still are. They have a double area of meaning: a very sweet and comforting one, related to stories and learnings which are important for each individual; and another one, regarding something we feel to have lost. This is not clear, I know. :)
Anyway, Thomas Milton has nothing to do with this object. His "Paradise Lost" too talks about something we lost, of course, but it is didactically religious.
I liked the title anyway.
