Greetings---

If I remember my Art History classes, the Romans were the first to use this
"medium"......let me consult one of my old textbooks:

"Roman architects relied heavily on the round arch and barrel vaulting.
Beginning in the second century BCE, they also relied increasingly on a new
building material, "cast CONCRETE".

-----"Art History", Stokstad.M. , 1995 Prentice Hall/Abrams.

....a significant breakthrough !
