For those who don't know why that's interesting: The tradional practice for creating these kinds of texts is to first write an editio typica in Latin. This Latin text is then the basis for translations into vernacular languages.
Although, it's called Latin America many countries speak variations of spanish and Brazil speak portuguese, just because those languages derived from latin and not because there the people speak it
Indeed, the beginning of the Italian text is: "La magnifica umanità creata da Dio si trova oggi..." from which, Magnifica Humanitas.
