About this source
What it is
The Pillow Book is a collection of essays, lists, poems and anecdotes written by Sei Shōnagon, a court lady who served Empress Teishi in the 990s and early 1000s. It was completed around 1002, during the Heian period in Japan.
Why it matters
Sei Shōnagon served a rival court to the one Murasaki Shikibu knew, and Murasaki criticised her sharply in her own diary. Comparing their writing helps students see how two of the greatest Heian women writers viewed each other and their world differently.
Look closer
- What kinds of things does Sei Shōnagon choose to write about?
- Why might a court lady write mainly for herself rather than for a wide audience?
- What does the rivalry between these two writers tell you about court life at the time?
