For centuries, concrete was everywhere in Roman Italy: in the awesomely durable breakwaters of artificial harbors, in the soaring vaults of great baths, in the foundations of the Colosseum, and - of course - in the spectacular dome of the Pantheon. But during late antiquity, concrete all but vanished from the Mediterranean world, and would not be used widely again until the twentieth century. This video explains why.

They also forgot how to Wash during the Middle Ages

[Flick Lives]

Never mind the forgotten concrete. how did people forget about indoor plumbing, flush toilets, and baths during the Middle Ages?

I was going to say environmentalists....but muslims is the correct answer.

Yes it could set underwater. Made synthetic Zeolite and it worked fine for things like railroad ties but nobody wanted to pay the difference.

They did not know Ancient Chinese Sakrete

Why was Roman Concrete Forgotten during the Middle Ages?

Before the British Empire, the Roman Empire was the most advanced civilization in history, particularly in the fields of medicine and engineering. The Roman Empire was right on the edge of the industrial revolution, but didn't quite make it. In the middle of the second century the Romans invented prototypes of the first steam engine but did not figure out how to apply them in a factory, locomotive, or ship. Roman aversion to labor-saving devices is probably what held them back. After the breakup of the empire in the third century, it would take 1500 years for civilization to rediscover techniques and technology the Romans used.

Christian navel gazing, internecine conflicts all over Europe in the vacuum left by the Romans, several waves of plague, and the fact that concrete isn’t a substance, it’s a whole technology that requires a variety of trained people, made it difficult to reproduce what the Romans did.

“ Interesting - hubby agrees - says it could set underwater?”

Present day concrete cures underwater as well. The operative word is “cure.” 😊

That video was interesting...thanks for posting it.

Islam didn’t start for a coule if hindred years or so after Rome fell.

—
the muslim invasions destroyed countless libraries and people with knowledge in their war on Christianity and other traditional religions. There remained only what some muslims thought useful to them. The rest was burned. There was nothing and no one to pass down knowledge after the fall of Egypt, North Africa, the Levant, and Persia. 200 years after the fall of Rome, which itself was sacked and burned. By 1500 AD people were just beginning to recover what had been lost, and it was not until the middle 1800s that large ship building recovered.

Never mind the forgotten concrete. how did people forget about indoor plumbing, flush toilets, and baths during the Middle Ages?

Lingering, terrifying memories of the Roman dual-use of the tersorium as common toothbrush and toilet paper scared Europeans away from running water for two thousand (and counting in some places) years.



(Just kidding about the toothbrush... Romans just rinsed with urine.)

“The populace realized concrete was racist during the Middle Ages and stopped using it. Then we went backwards again later, and it’s only gotten worse ever since. Allahu Ackbar.”

Very interesting video. Slightly off topic is that many of the durable ruins in Rome today are the concrete and brick cores of buildings whose marble facing was recycled for the monumental buildings of the Renaissance. Likewise much bronze decorative work and the sheathing of the Pantheon dome

For centuries, concrete was everywhere in Roman Italy

That's because the guys from Sicily had all of the cement contracts.

Large populations with intense specialization allows all sorts of things you can’t do when people make their own shoes and grow their own food. Civilization took a huge “pause” after the Roman Empire fell.

Imagine the things we have today that we wouldn’t have if, say, a large portion of people are killed, by, say, a bad vaccine. Steel products. Cars. Gasoline. Cell phones. Kill off half of the world population, as numerous enviro-nuts and liberals want, and suddenly lots of things we take for granted just vanish. Coffee in norther climes. Cheap transportation. Electric power...just imagine the infrastructure required for that...

Our civilization is fragile. And, most of us wouldn’t recognize food in the wild. If it doesn’t grow naturally on a Styrofoam tray we’d starve.

Modern historians hate specifically dating the "fall" of large, vague institutions like the Roman Empire. The fall wasn't so much a pinpoint event in time as much as it was a decline across the timeline. You know, just like U.S.

[normbal]

torching the library at Alexandria wasn’t a good thing the ‘slims did? Who knew.
