Dante Alighieri (1265–1321) was a Florentine poet and philosopher. Banished from Florence when his political enemies took power in 1301, he is best known for his works The New Life and The Divine Comedy, as well as his essay De vulgari eleoquentia, a defense of the use of the vernacular in literature. He died in exile, in Ravenna.
