In our adopted Tuscan hometown Arezzo, stands a monument to the 14th century poet and Father of Humanism, Petrarch - Petrarca in Italian.
That statue is in Parco Prato a couple of hundred steps from here - the home where he was born. Inside is a massive library full of artifacts and manuscripts from him and from his time.
In addition to Dante, the writings of Petrarch make up the foundations of modern Italian.
While I have not yet read him in Italian, in English there are scores of introspective quotes:
"Man has no greater enemy than himself."
