Note 1 — CANTO XV.

Brunetto Latini, one of the most learned and able Florentines of the thirteenth century. He was banished with the other chiefs of the Guelph party, after the battle of Montaperti, in 1260, and went to France, where he resided for many years. After his return to Florence he became Secretary of the Commune, and he was the master of Dante and Guido Cavalcanti. His principal literary work was Li Livres dou Tresor, written in French, an interesting compend of the omne scibile. He died in 1290. Dante uses the plural “you” in addressing him, as a sign of respect.
