I think it's false. I may be wrong. Sorry if i am
I believe the answer you are looking for is the "Neolithic Period".
The Volga river is the largest river in Europe, so that should be the answer.
You would go through these is this general order:
Palaestra- exercise room, socialization, preparation for baths basically
Apodyterium- changing room, to get... changed?
Tepidarium- warm bath room, spend time sitting in a warm room. Prepare for the next room
Caldarium- hot bath room, hot water to soak in. After that slaves come rub you down with olive oil (soap was not invented yet)
Frigidarium- cold plunge bath, rinse down the oil with cold water
All hot room were heated by hypocausts, a way of hot air circulating through walls and beneath the floors
tada
Wind shear, the updraft is high speed and wind shear is good enough, you’ve got a supercelluar funnel cloud
