Dante's Divine Comedy describes his journey through Hell, Purgatory, and Heaven. In Hell, sinners are organized into concentric circles based on their sins and receive specific punishments. Purgatory involves purification and climbing its terraces to erase the seven deadly sins. In Heaven, Dante is guided by Beatrice through the nine celestial spheres, finally glimpsing God at the top. The poem had a profound influence on literature and examines the poetic interpretation of the afterlife.
