Dante Alighieri [SEP] Works
Most of Dante's literary work was composed after his exile in 1301. "La Vita Nuova" ("The New Life") is the only major work that predates it; it is a collection of lyric poems (sonnets and songs) with commentary in prose, ostensibly intended to be circulated in manuscript form, as was customary for such poems. It also contains, or constructs, the story of his love for Beatrice Portinari, who later served as the ultimate symbol of salvation in the "Comedy", a function already indicated in the final pages of the "Vita Nuova". The work contains many of Dante's love poems in Tuscan, which was not unprecedented; the vernacular had been regularly used for lyric works before, during all the thirteenth century.
