A pilgrim undertakes an allegorical traversal of the afterlife, passing through a realm of retribution, a mountain of purification, and a celestial hierarchy of blessedness. Guided initially by a classical poet and later by other spiritual figures, the traveler witnesses symbolic punishments and penances, holds instructive conversations with a wide range of souls, and ascends toward divine vision. The work unfolds as a sequence of cantos that blend vivid, often grotesque imagery with theological and moral reflection, exploring sin, justice, repentance, and the soul’s progression from darkness into beatitude.
