Scientists have discovered concrete-like rock in a dormant volcano in Italy, and say it may explain why the Romans were able to invent the legendary compound used to construct the Pantheon and the Colosseum.
The concrete rock was found at the Campi Flegrei volcano near Naples.
“This implies the existence of a natural process in the subsurface of Campi Flegrei that is similar to the one that is used to produce concrete,” says Tiziana Vanorio, an experimental geophysicist at the Stanford University School of Earth, Energy & Environmental Sciences.
The Romans were keen observers of the natural world and fine empiricists.
