Explore the Diamond Sūtra: The World’s Earliest Dated and Printed Book in Existence
Like its namesake stone, the Diamond Sūtra was found underground. In 1900, a Buddhist monk in the Gansu province of China stumbled upon a sealed entrance leading to a series of 492 connected caves. The site had been closed off to the world since the start of the 11th century. Once a major Buddhist center, the area is known as Mogao (“Peerless”) Caves or the Caves of a Thousand Buddhas.
