Hi UncleG,
I tend to think whoever made these sorts of things would have had to write down a hell of a lot. You can’t just knock up something as complicated as this without some planning. What size gears? How many teeth? How should the teeth be cut? Will the gear push another gear or a lever? Gear ratios? It could possibly represent the labours of many individuals all of whom have to be coordinated.
Even if it represents the hobby of some guy and not an actual commission, the fact is you are going to need an incredible education to make this, with a long history of making similar but possibly less complicated devices.
So I think that the device implies the existence of some form of written and drawn documentation. Furthermore a master would have had to train his apprentices in the skill of planning this stuff. So I could see the project documentation surviving as a teaching aid. Probably guarded heavily. I’m thinking Harrisons reluctance to reveal details about his clock to the Longitude committee.
So I’m still curious about critical mass of people capable of making such devices. What is required to make it a stable enterprise? I’m still thinking Rich Mans toy that went out of fashion as no one could think of a practical use for it.[/quote]
I agree with you.
I would say it was definitely the work of multiple craftsmen. Maybe one genius with multiple craftsmen under him who could not comprehend the whole but were skilled enough to do the pieces assigned to them.
They probably sketched out technical schematics and diagrams of a sort. But paper does not survive long. The ancient texts that survived did so because scribes and monks copied them out by hand every few centuries or so. Most monks/scribes probably wouldn’t know what to make of such drawings, and probably wouldn’t bother to copy them out.
Off the top of my head I’m not sure what kind of medium they used as paper then, whether it was papyrus or parchment (and I’m not going to google it just to look smart) but that may have been prohibitively expensive, especially in the days before erasers, so they may have used a different medium all together, wood or plaster for example.
Then there’s all the ways that such things can perish. Fires accidental, fires intentional. Cities get sacked, or monks and imams get wild hairs up their asses and start purging works that are pagan or “anti-Islam” or whatever.
In short, I would not speculate as to why the drawings didn’t survive, but rather I would be in awe that any of the written words we have did.
