I knew the first one was a myth. One that Rome salted Carthage so that it would not rise again. The other that the word salary comes from Rome paying its soldiers in salt.
That the Carthage one took hold so well is confusing. The other one though I can see how it would get so embedded despite a lack of evidence.
By the way, the Wieliczka salt mines are a great tour.
