Paper

105 ad

In 105 AD, a court eunuch named Tsai Lun reported the invention of papermaking to Emperor Wu Di of the Han Dynasty. As a result, Tsai Lun is often credited with the actual invention of paper, although it seems likely that the technique was discovered much earlier. The first Chinese paper was made from hemp and other plant fibres, soaked, and then spread over a screen to dry. From China, this technology spread to Korea, Japan, Tibet, Central Asia, and then into the Middle East, and eventually, Europe.
