Cave 17 at Dunhuang: The Library Cave
An evidence-based introduction to the Mogao Library Cave, its manuscript cache, and the complex history of dispersal and study.
What Cave 17 is
Cave 17 is a small side chamber connected to the corridor of Mogao Cave 16. Its modest size contrasts with the scale of what it held: tens of thousands of manuscripts and many paintings, prints, textiles and other objects accumulated before the chamber was sealed.
Why it is called the Library Cave
“Library Cave” is a modern descriptive name. The chamber was not a public reading room arranged like a modern library. Bundles and objects had been stored densely inside. Their subjects range from Buddhist sutras and commentaries to contracts, letters, calendars, administrative records and medical or divinatory material.
The archive also preserves multiple languages and scripts. Chinese and Tibetan are prominent, alongside Sanskrit, Khotanese, Sogdian, Old Uyghur and other evidence of translation and contact across the Silk Roads.
Who opened the chamber
In 1900, Wang Yuanlu, a Daoist priest and caretaker at Mogao, found the sealed opening. He became the chamber’s keyholder while seeking official interest and funds for work at the caves.
The reopening was not followed by a modern archaeological excavation. Objects were examined, moved, given away and sold under conditions that would be unacceptable today.
Why was Cave 17 sealed?
The written dates suggest sealing in the early eleventh century, but the reason is not known with certainty. One theory emphasizes protection during a period of possible military threat. Another sees the chamber as a repository for sacred, damaged or no-longer-used material that could not simply be discarded. The variety and arrangement of contents continue to shape debate.
Avoid any article claiming a single solved mystery unless it explains the evidence and uncertainty.
Stein, Pelliot and dispersal
Aurel Stein acquired a large group in 1907 with the assistance of Jiang Xiaowan. Paul Pelliot examined and selected another group in 1908. Other materials went to Chinese, Russian, Japanese and additional collections.
The collection’s dispersal across institutions is also part of the story, tied to unequal encounters and early twentieth-century collecting. The International Dunhuang Programme helps reunite many materials digitally for research and public access.
The most famous printed object
The 868 Chinese Diamond Sutra is often described as the world’s earliest complete dated printed book. Its fame should not obscure thousands of ordinary documents whose value lies precisely in their record of work, family, religion and administration.
How to explore the archive now
The physical materials are spread across many institutions. The International Dunhuang Programme provides a digital bridge among them. Approach Cave 17 as an archive with contested histories—not a chamber of invented secrets, supernatural codes or treasure-hunt claims.
