The world’s oldest novel is now a little bit longer after a whole new chapter of the volume was discovered in Japan.

The writing, from the 11th Century book “The Tale of Genji,” had been tucked away in a chest owned by an aristocratic Japanese family in Tokyo, CNN reported. The book was written by Japanese noblewoman Murasaki Shikibu.

The novel tells the story of the courtship of Prince Genji to Murasaki-no-ue. While the original and its 54 chapters no longer survive, there is a version transcribed by poet Fujiwara no Teika who lived around the same time.

Scholars who examined the new chapter confirmed that it came from the Teika transcription.
