:') When ya got a lot more wealth than ya need, and have hundreds of new slaves to put to work, ya buy (or more likely, confiscate) some land out in the country and put 'em to work farming it and caring for the herds and flocks. Of course, that just makes ya wealthier, so when some general leads the legions down to pulverize, say, the non-Romans in the Bay of Naples, and ya hear about how nice it is, well...
There was a documentary about the fish farms built by the Romans that was on cable recently—but the pictures weren’t as good about the interior of the villas. Maybe they couldnt get permission to shoot or something.
It focused on the engineering.
