On May 11, 868 C.E., something remarkable happened in China that would revolutionise how historians understood the history of printing. The Buddhist scripture called the Diamond Sutra was printed and disseminated by an individual named Wang Jie. While this might have been perceived as a religious practice at the time, many years later, it would become one of the most critical achievements in human history.What makes the Diamond Sutra unique is not just its age but its preservation as well. This scroll dates back over 1,100 years and was eventually buried within a cave located in northwest China. Years passed until it was discovered by researchers who quickly realised that they had found the oldest surviving complete printed book with a definite publication date.In addition to being a religious artefact, it provided an insight into the level of development of China during the Tang dynasty period. The Diamond Sutra also demonstrated that printing techniques were highly advanced even before Johannes Gutenberg invented the printing press in Europe.
How the world’s oldest printed book survived for more than a thousand years
Woodblock printing was used in creating the Diamond Sutra. Woodblock printing was an innovation already prevalent in China during the 9th century. In contrast to movable type printing, which was introduced many centuries later, woodblock printing required the craftsmen to carve an entire page of writing and illustrations on a wooden board.Every stroke needed to be carefully engraved backwards. After the engraving, the board would be inked, and sheets of paper would be applied to produce printed pages. The pages would then be sewn together into a continuous scroll that measured about sixteen feet in length. A single error committed during the engraving process would render the whole board useless, requiring the craftsmen to start over. Nevertheless, the technique enabled religious writings to be duplicated more swiftly than by hand-copying.
The sacred artwork and the hidden cave that protected the Diamond Sutra
The document included images of Buddha at the start, indicating the close relationship of Buddhism with art in Tang China. The colophon written by Wang Jie at the end provided information on the purpose of the document and documented the exact printing date. This information is important to historians since it pinpoints the actual date when the document was created. The Diamond Sutra, along with thousands of documents, was housed in a secret cave located near Dunhuang, northwestern China before the year 1000 C.E. The cave, which is referred to as the Mogao Caves, is located along the Silk Road and includes hundreds of caves hewn out of stone cliffs.One chamber, later called Cave 17 or the Library Cave, was sealed and remained untouched for nearly nine hundred years. Historians are still uncertain why the cave was closed, though some believe the manuscripts were hidden for protection during periods of unrest.
The hidden cave discovery that revealed the world’s oldest printed book
Wang Yuanlu was a Taoist monk who came across the Library Cave when conducting restoration activities in the region around 1900. It contained several thousand manuscripts, paintings, and religious books that had been kept there for centuries. The discovery was made known to foreigners who were traveling across the central parts of Asia as archaeologists and explorers. For instance, Aurel Stein was a Hungarian-British explorer who traveled to these regions and investigated the manuscripts. He ended up taking away most of the books, including the Diamond Sutra, and transporting them to England, where they now exist in the British Library.
Enduring significance of the Diamond Sutra in world history
The Diamond Sutra is not just an old religious document. It marks a major milestone in the evolution of communication and knowledge transfer. Well before the invention of modern books, newspapers, and online publications, people had discovered techniques to copy and disseminate information on a mass scale. The preservation of the document for over a thousand years is equally impressive. Starting from its discovery in the Dunhuang caves, the scroll has traversed several phases of human civilisation without suffering significant damage.
