That's unknown. Probably leather on the pistons and / or grease on the walls. There are no clues in the historical material.

Thank you for writing me something. But do it please in English so I can understand.

Merci!

I'm glad you liked the video. About the metal pipes: almost the complete organ was made of bronze, including the pipes. About the inventor: Ktesibios did work on his Hydraulis at the "University" of Alexandria where he studied, so he had the helping hand of some of the greatest scientists of that time, possibly even of Archimedes. I would of course like to reconstruct a hydraulis, but I'am afraid that such a project is very expensive and time-consuming. Moreover: The hydraulis is not only the grand-daddy of all organs, but in fact the ancester of all keyboard-driven instruments because Ktesibios invented the use of a key to make a sound. Just 2200 years ago.

I'am glad she did.

You are absolutely right. It took the organ builders in Western Europe about 800 years to develop a mechanical system with bellows just as good.

There's nothing wrong with that and can be used for tremolo effect. Also it's actually not an issue as long as your slaves pump properly in sync. The main issue is didn't have as powerful a sound when they went to straight air.

You can't find it anywhere. I made it myself, to help the viewers understand.

Thank you for this reaction.

Glad it was usefull.

My pleasure. Glad you liked it. I wonder if you looked at the more elaborate version : Hydraulis 2 th-cam.com/video/5D-xMANSL1w/w-d-xo.html

Het is helemaal waar. Het geldt alleen niet voor alle pijpen; vooral kleine pijpen worden anders gestemd en tongwerken ook.

He did tho

Glad you liked it.

That's right!

I was going to say, this is a Uilleann bagpipe, but using a water column instead of muscles to keep the pressure constant, and whistles instead of reeds to generate the sound.

The Greek made also a cheap version of the extremely expensive HYDRAULIS, named PNEUMATIKON. It was made of wood, where the H. was made of bronze, and was powered by two bellows. It was a small instrument.

@@robvanhaarlem6706 Thank you, I thought there had to be a simpler engineering solution and according to Julius Pollux it seems the more complex system was associated with the size of the instrument, after some searching I found this statement : "A complicated water-driven system for air supply was gradually replaced by bellows; nevertheless, the name hydraulis was retained for the organ until the Middle Ages."

around 1st century AD there already existed a sort of a steam engine called Aeolipile. there are no records of it being put to practical use though. perhaps slave or animal labor was so abundant in rome at that time that there was no sense of prospective advantage in such invention. one of the hypothetical reasons on why chinese civilization stagnated was its constant surplus of human labor which resulted in little opennes to technological innovation. perhaps a parallel phenomenon took place in rome. anyway, implications of such an invention being put to actual use in roman times would be profound. rome was already great at infrastructure, so after creating a steam engine they could come up with railroad which could introduce another level of governance, economic progress and warfare.

It would be a very long time after the Romans until steel could be made in large enough amounts (if tat all) to create a pressure vessel. They may have recognized the ability of heat to create pressure, but getting a piston to return where it came from would be difficult, and blacksmithing a piston to fit in a chamber would be impossible. The Romans also did not have access to coal except very late in their existence and only in the distant colony of England.

@@cheetoman23 they could make finer mechanisms by filing or through the use of a primitive Lathe. Proof of this is the antikythera mechanism.

@@tfist apparently the guy who made the aeolipile also designed a device which could open doors. From what I understand vapor is generated in a chamber and flows through a pipe to another chamber full o water, the water them flows to a bucket which comes down and open the gates. This design would totally work in the place of the pistons of the organ. There is no evidence it was ever built though.

You should ask them

yes send help

ayyy

Thank you!

That’s really interesting! How so?

@@iriscecil8605 Very interesting! mmm I think I made a drawing of the historical relationship between music and computing, do you have something where I can send it? instagram, fb, email? Understanding it graphically would be ideal

Glad I could help you!

I'm glad you enjoy it. Thank you for your reaction.

Ce n'est pas correct. Pepin a reçu un "PNEUMATIKON". Il s'agit d'une version en bois bon marché de l'HYDRAULIS en bronze, qui était équipée de deux soufflets réguliers. Plus d'informations à ce sujet dans un futur article sur mon site : robvanhaarlem.com.

Glad you enjoy it!

grazie

That's correct. But it took us almost 1000 years to have the wind supply as smooth as the greeks had 2200 years ago!
