The Archaeologist

The excavation of the Villa della Pisanella in Boscoreale has yielded one of the most extraordinary archaeological finds of the Roman era: the world's only known intact Roman boiler, complete with all its pipes, valves, and accessories. This unique artifact provides a fascinating insight into the technological sophistication of the ancient Romans, highlighting their advanced engineering skills and meticulous craftsmanship...
The Villa della Pisanella first came to light in November 1868, when Modestino Pulzella, while laying the foundations for a new wall, discovered remnants of ancient structures. Further exploration revealed mosaics, but the work was soon halted by a neighboring landowner, Vincenzo De Prisco, who feared damage to his property. It wasn't until September 1894, nearly three decades later, that excavations resumed. This time, De Prisco himself initiated the work, having apparently set aside his earlier concerns.
This renewed effort led to the discovery of the famous "Boscoreale Treasure," a collection of exquisite artifacts that were regrettably sold abroad due to inadequate legal protections for cultural heritage. Despite this loss, the excavations continued, and in May 1896, the remarkable discovery of the Roman baths and the intact boiler was made. De Prisco subsequently restored part of the villa, converting it into a private museum known as the "Museo De Prisco." During this time, the Alinari Brothers, renowned photographers, captured an extraordinary image of the site, preserving its legacy for future generations.

Alas. I think it’s out of warranty
I didn’t know that they had pipes.
>> I think it’s out of warranty
ROFL! I like the way you think!
Pretty cool. To find it with intact plumbing is a pleasant surprise... Lead pipes, bronze valves.
Someone on Twitter made the point that these previous civilizations were more advanced than what we first observe from the visible artifacts, which would be the most primitive structures made out of the least valuable materials.
(copper, bronze, brass etc would be looted. Kind of like Detroit...)
Looks like a still

Hello?
We are contacting you about an extended warranty on your boiler.
And I thought we were doing well with our 1974 Sears furnace still firing up every fall.
This is our final offer to extend your warranty. Get an even better rate by also insuring your chariot.
Incredible!
Ancient Roman Plumbers charged a fortune!......
Not a lot of difference.......😁
They refused the annual maintenance contract.
The Romans didn't use a pressurized water system: water flowed continuously, so there was little chance it would pick up enough lead to be dangerous. Plus the water sources for aqueducts were selected to have a modicum of mineral content, which would coat the inside of the pipes, further reducing lead absorption.
Apparently it was used to provide heat by circulating hot water instead of a full-fledged hypocaust.
My guess is this was a necessary expedient in the drier but highly populated Bay of Naples area where firewood would have been scarce.
It wasn't really "engineered" in the modern sense: I doubt its makers would have known how even to calculate its volume. It was artisanal production, built by men who were taught artisanal production techniques learned from generation to generation, like Japanese sword making. Look at Gothic Cathedrals. The builders knew nothing about load-bearing tables or geometry. But they knew from experience that a ratio of x and y would bear a load and used ropes and lines drawn in sand to model how to cut the stone needed for an arch.
When demand for such instruments declined along with the decline if the Imperium, the knowledge of how to build such apparatus died with the last generation of makers. The letters of Ruricius of Limoges (c. 440–507) document the life of a Gallo-Roman nobleman who complained that with the death of cities it was no longer possible to find plumbers to fix his villa's baths and he had to bathe in the river.
It’s called a composite
