To these years belong the last three letters now known: Epistle XI (June 1314); Epistle XII (May 1315); and Epistle XIII (c. 1316; dedicating Paradise to Cangrande). This began the final stage in the life of Dante: he left Verona about 131.8 and went to Ravenna as guest of the poet Guido da Polenta. In the tranquility of Ravenna, his surviving children gathered round him: Pietro, Iacopo, and Antonia (who after the death of her father was to become a nun, taking the name of Sister Beatrice). He composed two Latin eclogues there in reply to Giovanni del Virgilio (a Bolognese grammarian)l. He may have stayed briefly at Verona. On his return to Ravenna from Venice, where he had been sent on a difficult embassy by Guido da Polenta, Dante, who had only very recently finished Paradise, was struck down by malaria and died during the night of September 13-14, 1321. But he left to Italy and to the world the Commedia, which posterity judged to be divine.
