The evolution of P/F vs T/K raises important questions

[Mauro]

For years I have been pondering the question of why someone who was educated in Latin would want to create a work that was not in Latin.  There are several possible answers.  I think the most common ones that have been offered are:

- it's gibberish (maybe he started hearing voices in his head)
- he wanted to hide the knowledge he was sharing about the topic (very odd considering all the illustrations)
- he wanted to share the information in a language other than Latin (possibly for people who did not know Latin)

Dante, Petrarca and Boccaccio (and others), around ~1300, were all educated in Latin (Dante also wrote in Latin) but then they choose a different language for their works. In this case it was because they loved their motherlanguage and it fit their artistic sensitivity and aims. Add a sprinkle of good old parochial pride, I guess   .

I really don't know if 'wanted to share the information in a language other than Latin' was really a factor for them, but I guess no, because at those times Dante's language was barely known outside of Florence or maybe Tuscany, Latin could have reached a much wider audience. I may be completely wrong.
