Stein's greatest discovery was made at the Mogao Caves also known as "Caves of the Thousand Buddhas", near Dunhuang in 1907. It was there that he discovered a printed copy of the "Diamond Sutra", the world's oldest printed text, dating to AD 868, along with 40,000 other scrolls (all removed by gradually winning the confidence and bribing the Taoist caretaker). He took 24 cases of manuscripts and 4 cases of paintings and relics. He was knighted for his efforts, but Chinese nationalists dubbed him a burglar and staged protests against him. His discovery inspired other French, Russian, Japanese, and Chinese treasure hunters and explorers who also took their toll on the collection.
