The Pillow Book of Sei Shonagon

996 A.D., with later revisions. The translation of the diaries of a court lady in tenth-century Japan, it is a collection of anecdotes, memories of court and religious ceremonies, character sketches, lists of things the author enjoyed or loathed, places that interested her, diary entries, descriptions of nature, pilgrimages, conversations, poetry exchanges--indeed, almost everything that made up daily life for the upper classes in Japan during the Heian period.
