Dante Alighieri 
The Divine Comedy by Dante, Illustrated, Purgatory, Complete 

‚Purgatory‘ is the second part of Dante’s Divine Comedy, following the ‚Inferno‘ and preceding the ‚Paradiso‘. The poem was written in the early 14th century. It is an allegory telling of the climb of Dante up the Mount of Purgatory, guided by the Roman poet Virgil—except for the last four cantos, at which point Beatrice takes over as Dante’s guide.
