The fact that in the Tsin Dynasty (#), 303-379 AD, the technique had been widely used, and about the seventh or eighth century the Chinese already used woodblock to print calendars (Ɔ).
The oldest woodblock printed book still in existence, so far as we understand, is the Diamond Sutra (✨#∞) a Buddhist text (**) printed in the year 868 AD, which was found along with thousands of manuscripts from Mokao (†) the Caves of the Thousand Buddhas (†) at Tun-huang ( ). Tun-huang, a city situated on the outskirt of the Lob Desert in western Kansu Province (+), was once the main gate of the Old Silk Road (***). From the first century until the fourteenth century, merchants, caravans, travellers, monks, and armies leaving for the West all passed through Tun-huang on their way to the Middle East, the Mediterranean, and Europe. The Italian merchant Marco Polo („§ +) used the same route to come to China.
Hollowed out in irregular tiers along the face of a steep cliff, the cave temples of the Thousand Buddhas were known in the Tang Dynasty () as Mokao or “Grottos of Surpassing Height". They are located a few miles southeast of Tun-huang City. There had been huge Buddhist monasteries at the place for centuries, but it became forgotten when the Ming Dynasty (#9) began trading with the West by sea, and since then most of the caves had been buried by the shifting sand of the desert. In the late nineteenth century, it was rediscovered by a Taoist Priest called Wang Yuan-lu (10*), but by then all the wooden structures of the monasteries had vanished, and only the stone caves used as shrines remained.
Mokao is more than five thousand feet in length and consists of four hundred and ninety-two caves of various sizes. Over two thousand Buddhist statues and numerous huge murals can still be found in the caves. If we could have all the murals linked together, they would be at least twenty-five miles long.
In the year 1899, Wang Yuan-lu discovered an old monastery library in a walled-up chamber behind a mural in one of the caves. In the chamber, he found more than twenty thousand volumes of manuscripts and woodblock-printed documents and books, among them the Diamond Sutra. The news of the discovery soon spread abroad. In 1907 an Englishman, Sir Aurel Stein, traded with the priest and carried away 29 cases of manuscripts and books. More
