No one was allowed to open it until digitization – The world’s oldest multicolored printed book created in 1633
The world’s oldest multicolored printed book, Manual of Calligraphy and Painting (Shi zhu zhai shu hua pu) by Ten Bamboo Studio based in Nanjing in 1633, is now available for the public eye for the first time and digitized by Cambridge University Library’s Digital Library site. The 17th book has 8 sections of subjects illustrated by 50 different artists and calligraphers, including birds, plants, fruit, rocks, flowers and other miscellaneous subjects, after about four hundred years, which is so fragile that it’s forbidden to be opened until digitization.
