Biography

Sei Shōnagon was a Japanese noblewoman and ladyinwaiting whose wit and literary genius defined Heian court culture. Her masterwork, The Pillow Book, revolutionized prose by blending personal essays, lists, and sharp social commentary into an entirely new literary form. Her unflinching observations of beauty, absurdity, and human nature remain startlingly modern.
