Carthage`s destruction

[Mulceber]

but I had never heard before of the connection between the "pinch of salt" expression and the myth of the salting of Carthage.

I don't think there is one - I think that's just the author making a play on words to create a clever title.

There is no historical documentation stating that Rome salted the ground of Carthage after the Third Punic War. In all actuality; Carthage became a wealthy province of Rome and flourished for hundreds of years.

ehm...kind of. Carthage did become a wealthy province, but that was 100 years later. It was completely annihilated in the war and was uninhabited for quite some time. IIRC, Caius Gracchus tried to start a colony there, but it never really got off the ground, and the city of Carthage wasn't rehabilitated until Caesar founded a colony there. -M
