Purgatorio (Italian for "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. In the poem, Purgatory is depicted as a mountain in the Southern Hemisphere, consisting of a bottom section (Ante-Purgatory), seven levels of suffering and spiritual growth (associated with the seven deadly sins), and finally the Earthly Paradise at the top. Allegorically, the poem represents the Christian life, and in describing the climb Dante discusses the nature of sin, examples of vice and virtue, and moral issues in politics and in the Church. The poem outlines a theory that all sin arises from love – either perverted love directed towards others' harm, or deficient love, or the disordered love of good things.
