Dante Timeline

Here's the timeline I'm putting at the front of Valley of the Dead:

Timeline of Dante’s Life

1265 Born in Florence, Italy

1274 Sees Beatrice Portinari for the first time

1283 Marries Gemma Donati, with whom he has four children

1289 Fights in the Battle of Campaldino

1290 Beatrice dies

1292 Begins writing The New Life (La Vita Nuova)

Politics

1302 Banished from Florence under pain of being burned alive

Of course, the crucial entry that sets everything up is the "whereabouts unknown" one!
