I don't want modern day Italian translations im looking for Italian that was spoken in the FIFTEENTH CENTURYAre there any site that can provide a FREE translation of english to OLD Italian (NOT modern Italian)?
No, there isn't. It would be practically impossible to "translate" diachronically over a space of 500 years, even by hand, even if you speak the modern language very well indeed. The text would have to be practically rewritten - it's not just a question of grammar and vocabulary, they wrote in a completely different style back then.
A very few literary greats like Dario Fo have written successfully in medieval language. You would need real talent as a writer to pull this off, even a translation of a text written by someone else, and you would also need a very good knowledge of the history and literature of the period. Not something that can be done by a computer programme. And the first answerer is right - these automatic translators are completely hopeless anyway.Are there any site that can provide a FREE translation of english to OLD Italian (NOT modern Italian)?
I bet there is no such Web site. Neither one that charges you.
Your only chance is to pay a human. But there aren't many with such skill.
Anyway I think there is not even a free Web site that can provide a GOOD free translation of English to MODERN Italian.
