I just located a source for the Diderot books just

mentioned. It is such a fascinating set of plates showing the

way things were made in the 1700's that I felt others would love

to know the source. It covers not just the items and media from

gold and silver smithing to pile driving, to weaving to glass

blowing to wig making to the nobility's stone work patterns to

metal casting to power sources to farming, etc. but also the

buildings, layout, principles, etc. in exploded view and diagram

form Also the designs of the tapestries, the ornamentation's on

the armaments, the many ways water wheels worked, etc..

(The one I liked best and used for casting metals was a blower

system for the furnace. The foundry was located near a stream

with a high head of water. The flow was captured into a

hollowed log or pipe and dropped down into a much larger sealed

barrel with the bottom under water and open in the deep stream

below. At the near top of the pipe were small venturi holes

that sucked air in as the water entered so the flow dropping was

filled with bubbles which then became released but under

pressure once the flow entered the barrel. Another pipe left

the top of the barrel and ran over to the forge or melting

furnace burner where the coal or charcoal or wood was set and

the forced air now was controlled by opening or shutting a cock

valve. No bellows with this one, no workers pumping like crazy

all day to compress air, no pulse of a bellows and no multiple

bellows to mute the pulse, no horse shit lying on the ground

around where they worked to pump a bellow, no flies around the

shit. Of course you had all that extra ozone knocking out the

hole above the Arctic circle but hey it's France in 1750 .)

The original 17 volume set was the first Encyclopedia ever

made and printed and was the turning point for science and

scientific investigating. Prior to this the kings or wise men

and scholars simply told you how it was (seldom with any first

hand knowledge) and there were so many totally bull shit

concepts held as truth that it is amazing man could rise above

it or even get to that point. Just one reason man progressed so

slowly back then. Luckily the common man paid more attention to

what worked vs. what didn't so he did raise above it but Diderot

was the (very unpopular) universal kickoff. His writings

covered all aspects of life (starting out on the first pages and

revealing that there was absolutely nothing to the established

medical King's wisdom saying that male and female babies each

said ohh vs. ahh as their first uttered sounds. His

L'Encyclopidie was already under fire.)

His works took the dedication of many (over 140 ) to go to the factories and sit for months to do the engravings of all they could see to explain it to others. This of course also flew in the very secretive face of those in the know of each little process or step as these were their secret knowledge that defined them above the masses and allowed them to individually be of a higher respect and wealth. Can you imagine anyone today being like that? Hoarding knowledge I mean. It must have been awful. Boy I'm glad we're not like that.

Anyhow... This is a two volume sample with 485 plates and

this is one place you can find it. bpfink
