The Divine Comedy is an Italian narrative poem by Dante Alighieri, begun c. 1308 and completed around 1321, shortly before the author's death. It is widely considered the pre-eminent work in Italian literature and one of the greatest works of Western literature. The poem's imaginative vision of the afterlife is representative of the medieval worldview as it existed in the Western Church by the 14th century. It helped establish the Tuscan language, in which it is written, as the standardized Italian language. It is divided into three parts: Inferno, Purgatorio, and Paradiso.

Publius Vergilius Maro, usually called Virgil or Vergil in English, was an ancient Roman poet of the Augustan period. He composed three of the most famous poems in Latin literature: the Eclogues, the Georgics, and the epic Aeneid. A number of minor poems, collected in the Appendix Vergiliana, were attributed to him in ancient times, but modern scholars consider his authorship of these poems to be dubious.
