The Divine Comedy (Italian: Commedia, later christened "Divina" by Giovanni Boccaccio), written by Dante Alighieri between 1308 and his death in 1321, is widely considered the central epic poem of Italian literature, and is seen as one of the greatest works of world literature. The poem's imaginative and allegorical vision of the Christian afterlife is a culmination of the medieval world-view as it had developed in the Western Church. It helped establish the Tuscan dialect in which it is written as the Italian standard.
More than 14,000 lines long, the Divine Comedy is composed of three canticas (Ital. pl. cantiche) — Inferno (Hell), Purgatorio (Purgatory), and Paradiso (Paradise) — each consisting of 33 cantos (Ital. pl. canti). An initial canto serves as an introduction to the poem and is generally not considered to be part of the first cantica, bringing the total number of cantos to 100. The number 3 is prominent in the work, represented here by the length of each cantica. The verse scheme used, terza rima, is hendecasyllabic (lines of eleven syllables), with the lines composing tercets according to the rhyme scheme aba, bcb, cdc, ded, ....
The poem is written in the first person, and tells of Dante's journey through the three realms of the dead, lasting during the Easter Triduum in the spring of 1300. The Roman poet Virgil guides him through Hell and Purgatory; Beatrice, Dante's ideal woman, guides him through Heaven. Beatrice was a Florentine woman whom he had met in childhood and admired from afar in the mode of the then-fashionable courtly love tradition which is highlighted in Dante's earlier work La Vita Nuova.
