Grand Fromage posted:A printing press would be one of the easiest transformative technologies to make. The hard part is the mechanism for the actual press and the Romans already had that. I always thought that it's the paper that makes having a printing press worthwhile, and that paper was only invented once by Tsai Lun. Now, my whole basis for that assertion is "100 Most Important People" -book I had in the 90s and read cover to cover while sitting on the toilet, but it makes sense to me still. Printing press with an easily produced, cheap writing material is recipe for pampleths, news papers, etc, and paper is good for notes and letters more so than anything else as far as I'm aware. But that's just it. Was there some other writing material comparable to paper that I'm not aware of? Grimnarsson fucked around with this message at 03:16 on Sep 21, 2019 |

You need a reasonably sturdy printing surface, paper or otherwise. Things like cloth will do just fine, the ancients used pprinting press techniques for them after all. That could be real pricey for a full book though. You need movable type since plain old printing press techniques were known form antiquity, but mostly used for producing decorative patterns on clothes and similar goods - since when you can't freely rearrange the letters you have to individually prepare printing-plates for each page of a work and that gets impractical very fast. You need inks that will work well on the printing surface you choose, while being able to stay on the type for running off large numbers of copies between re-inkings, while not leaving residue that causes too much of a cleaning problem for reusing the type.

Grimnarsson posted:But isn't that just the thing with paper, that it's cheap. Maybe not at first but ultimately so? And without that cheap medium, a printing press is not so useful. There was massive costs in labor and time to print before Gutenberg and the various similar systems over in East Asia, which were the major bulk of the costs. Paper being cheap helped for sure, but you would have had radical improvements in the price while using expensive printing material - being able to turn out multiple complete books a day for example, instead of taking a week in copyist time like a relatively short book with a lot of scribes at work would take. As an example of the speed you could publish between hand copying and fully fucntional movable type presses, a fast individual scribe of the 900s AD would be expected to be able to bang out a good quality transcription of the 4 main Gospels in about 2 weeks. In comparison, Gutenberg's initial 180 or so copies of the Bible printed took a year to produce in total - and that was with Gutenberg's print shop insisting on employing illustrators and rubricators to highlight important passages in red ink, have fancy initial letters on major pages, etc - averaging to 2 days or so for each entire 1282 page, 42 line per page, copy, with a lot of that time given over to fancying it up instead of straightforward printing. Oh and at the time of Gutenberg? Similar quality handwritten Bibles of the same contents and level of illustration would take a year to produce in the scriptoriums, by a dedicated team of scribes within the enterprise. (There is of course the fact that before you can start cranking out whole bibles in about 2 days a copy, you spent months beforehand preparing for it by casting type, figuring out optimal layouts etc. But once you start going, your output rate is phenomenal. With no cheap paper, you're not producing works every rando city dweller can afford, but you are producing works that all the middle class might afford without seriously dipping into their assets or wages.)

But where the Gutenberg press and paper really come together is pamphlets and news papers that are available for anyone, not so much books. But I guess books too if they aren't going for anything fancy as you describe. But yeah, the pop-history book I referenced made this exact point: the Gutenberg press plus the cheap medium (paper) made for an information revolution. Without one the other is impressive but not groundbreaking. I think the author credited the supposed inventor of paper higher than Gutenberg because as far as it was known the printing press was an engineering development and was invented multiple times in various places, while paper was only invented once and then spread from there.

Well no. It already came together for the books. If for some bizarre reason paper had not been available or paper had been available but at far higher prices, it would still have been revolutionary and groundbreaking. It would still have allowed mass-issuance of pamphlets and newspapers (which didn't become the modern several dozen to a hundred or so pages until within the last 150 years mind you) and their mass distribution, just with slightly reduced scopes that don't matter so much overall. You have Gutenberg and others mass producing books of all sorts well before 1500, while mass newspaper and widespread pamphleteering waited til the late 1600s/early 1700s for the most part, due to all sorts of incremental advancements that couldn't initially be done.

You need money for any of these technologies anyways- stuff like glassware or precision metalwork has only got cheaper over time. there's a reason distilling is always suggested as the first invention to make money, although where you'd get equipment to set up a still is another matter.

That's why Lest Darkness Fall stands out from similar time-traveling fantasies—the protagonist actually has to find a creditor first so he can buy the copper required. He also makes a bit of money from teaching decimal notation and double bookkeeping, but finds out quickly that the people he taught will happily sell the knowledge themselves.

If you wanted to ingratiate yourself with the powerful, the best thing to take back in time would be a big jar of viagra. Historically power has tended to accumulate in the hands of old men, and old men care about nothing as much as their fading virility. Give the king a pill which makes him sport wood, and you're looking at a bishopric minimum.

Let’s talk about printing. What if you couldn’t get moveable type or cheap paper going, but you could deliver a complete set of engraved lead plates of the Vulgate to the court of Charlemagne? They only have the one set, but it could print quite a few volumes before wearing out.

I debated whether I should give the plates to Big Chuck or to Jerome. Jerome already took enough fire for translating (large portions of) what would become the Vulgate. Producing thousands of perfect copies would turn some heads.
