Silk was the most famous thing to leave China along the trade routes, but not the most consequential. Paper, printing and gunpowder travelled the same roads, and they changed the societies that received them.[1]
Printing, and the oldest printed book
Woodblock printing is first mentioned in literature around 835 and the technique was perfected soon after. The earliest surviving printed book is an illustrated scroll of the Diamond Sutra, printed on paper and unearthed at Dunhuang, on the eastern end of the trade routes.[1]
The material underneath
Printing needs something to print on. Paper is made from plant fibre and water, which means it can be produced almost anywhere there is a stream and a crop – and that is why a printed book could be made in quantity and carried in a saddlebag.[1]
Powder, and what it was first for
Gunpowder – black powder – is generally held to have originated in China around the tenth century, where for a long time it was used almost exclusively for fireworks and signals rather than weapons. Its recipe is saltpetre, sulfur and charcoal, and a recipe is portable knowledge: by 1300 Arab forces had developed the first real gun. The interesting question for the road is not who had it first, but how fast a formula crosses a continent once somebody writes it down.[2]
The pattern behind all three
None of them travelled as a gift, and none stayed a secret for long. They moved with the people who used them – artisans, monks, soldiers, merchants – along a route that had no single owner and no single direction. The Silk Road’s most durable export was capability.[1][2]

Questions
What is the oldest surviving printed book?
An illustrated scroll of the Diamond Sutra, printed by woodblock, found at Dunhuang.
Which inventions travelled west from China?
Among them paper, printing and gunpowder – all of which moved along the trade routes that carried silk.
Why was paper so important?
It is made from fibre and water, so it could be produced cheaply almost anywhere. That reduced the cost of keeping any written record at all.
The film, in words
Every caption card that appears on screen in the film, in order. The film has no narration – this is its full text, so it can be read and quoted.
