WIill Pryce: "This library was ground-breaking. It established the template of using books to decorate the walls of the library which we've been using ever since. The great hall is a harmonious combination of bookshelves, books and a wonderful painted ceiling. It was complete by 1585 and influenced everything that followed it."
