The Pillow Book is right.Not Greenaway's best, i thought(i much prefer The Draughtsman's Contract) but the book it refers to (though the film is completely different)is The Pillow Book of Sei Shonagon, a diary of a court lady's life in 10th/11th century Japan(i can't remember the exact dates and i've lent the book out).It is wonderful, one of my favourites, if anyone's interested!
