"La Divina Commedia di Dante" by Dante Alighieri is an Italian narrative poem written between 1308 and 1321. The work follows Dante's journey through the three realms of the afterlife: Hell, Purgatory, and Heaven. Guided by the poet Virgil and later by Beatrice, Dante encounters souls receiving divine justice based on their earthly actions. The poem explores sin, redemption, and the soul's path toward God, drawing on medieval Catholic theology and philosophy while establishing the Tuscan language as standardized Italian.
