"La Divina Commedia di Dante: Purgatorio" by Dante Alighieri is the second part of the Divine Comedy written in the early 14th century. Guided by the Roman poet Virgil, Dante ascends the Mount of Purgatory, an island-mountain in the Southern Hemisphere where penitent souls cleanse themselves of sin. Through seven terraces corresponding to the deadly sins, Dante explores the nature of vice, virtue, and redemption. The journey examines how all sins arise from love—whether perverted, deficient, or excessive—as souls prepare themselves to ascend to Paradise.
