To me it depends on which route you want to take. The artsy fartsy route with Italian or Latin words, or the route everyone will understand where you use scene, setting, and background, including items of the period and clothing, instead of actual specific language to denote the era. You can always say "the man called out in Latin, a common language of travelers" or something of the like.

I'd go with the second. I barely remember Latin, anyways, and wouldn't have the patience to read a book littered with Latin, or any other language.

I even skip over all the made up languages like Klingon and Elven when reading a book, because quite frankly they bore me.
