Cai Lun was a eunuch who entered the service of theimperial palace in 75 CE and was made chief eunuch underthe emperor Hedi (reigned 88–105/106) of the Dong(Eastern) Han dynasty in the year 89. About the year 105Cai conceived the idea of forming sheets of paper from themacerated bark of trees, hemp waste, old rags, and fishnets.
The paper thus obtained was found to be superiorin writing quality to cloth made of pure silk (the principalwriting surface of the time), as well as being much lessexpensive to produce and having more abundant sources.
