Dante's Divine Comedy is considered to be not only the most important epic poem in Italian literature, but also one of the greatest poems ever written. It consists of 100 cantos, and (after an introductory canto) they are divided into three sections. Each section is 33 cantos in length, and they describe how Dante and a guide travel through Inferno, Purgatorio, and Paradiso.
The most famous of the three canticles that compose The Divine Comedy, "Inferno" describes Dante's descent into Hell midway through his life, with Virgil as a guide. As he descends through nine concentric circles of increasingly agonizing torture, Dante encounters doomed souls that include the pagan Aeneas, the liar Odysseus, the suicidal Cleopatra, and his own political enemies, damned for their deceit.
