In 1312 Henry, who, after the murder of Albert, had been crowned emperor (in 1309), came to Pisa, thence to Rome. Then, after having in vain besieged Florence, which had become the leader of the anti-imperial movement, he retired to Buonconvento, where he died (probably from poison) August 24, 1313. With the tragic death of Henry, Dante seems to have given up all hope of earthly happiness and from now on turned his eyes to heaven, from which alone he could hope for justice to himself and peace and righteousness for unhappy Italy. The composition of the Divine Comedy dates from this period. His final refuge and place of rest was at Ravenna, at the court of Guido da Polenta, uncle of Francesca da Rimini, whose pathetic story is quoted in the next chapter. Here, in comparative comfort and peace, he spent the evening of his life, occupying his time in writing the Divine Comedy and in occasional journeys in the interest of his patron. In 1321, while on one of these journeys to Venice, he caught fever and died on the 13th of September of that year. Many anecdotes and legends are told of these years of exile. Thus it is said that while in Verona, as he was walking one day through the streets, some women saw him and said: "Behold, there is the man who has been in hell." A beautiful story is told in a letter, doubtful however, written by Fra Ilario of the Monastery of Santa Croce on Monte Corvo, to the effect that one day a dust-stained, travel-worn man, carrying a roll of manuscript under his arm, knocked at the door of the monastery, and on being asked what he wanted, answered "pace, pace" (peace, peace). This legend has been beautifully rendered by Longfellow in the following lines: "Methinks I see thee stand with pallid cheeks By Fra Ilario in his diocese, As on the convent walls in golden streaks The ascending sunbeams mark the day's decrease. And as he asks what there the stranger seeks Thy voice along the cloisters whispers 'peace.'"
