First printed bookIn 868, the first known dated printed book was the Diamond Sutra, a Buddhist scripture. It was made as a 16-ft scroll with six sheets of text printed from wood blocks and one sheet with a woodcut showing the Buddha with disciples and a pair of cats. The sheets measured 12" by 30" and were pasted together. The date is known from a colophon at the end stating it was "printed on 11 May 868, by Wang Chieh, for free general distribution" and that it was dedicated to his parents. The scroll was one of about 1,130 bundles of manuscripts found a thousand years later, walled up in one of the Caves of the Thousand Buddhas in Turkestan. It is now one of the great treasures in the British Library.« |
