The Divine Comedy is Dante's record of his visionary adventure through the triple domains of Hell, Purgatory and Paradise.  

Purgatorio is the second piece of Dante's Divine Comedy, following the Inferno, and going before the Paradiso. The poem was composed in the mid fourteenth century. It is a moral story recounting the move of Dante up the Mount of Purgatory, guided by the Roman artist Virgil, aside from the last four cantos and soon thereafter Beatrice assumes control as Dante's guide.
