I find it interesting that the cities of the Indus Valley Civilization had sewage systems and most of the houses had toilets.
This knowledge seems to have gotten lost with the decline of their civilization. Some time the Indus Valley Civilization disappeared, some of their cities got reinhabited by other peoples, but they didn't use the sewage system and apparently didn't figure out what it was.
- paganel 4y agoThe same happened with the Romans where I live, in present-day Romania and the former province of Dacia. Back when they were here, around 100-200 AD, they used to have villas with heated floors. Once they left for good, in the late 200s - early 300s, no-one around these parts of the world had houses with heated floors for at least 1500 years. I'd say that in the early 1700s a local ruler was the first one who had such a system installed in its Bucharest court, meaning the first one after the Romans.
