Dante Alighieri's The Divine Comedy

The protagonist of this epic poem sets upon a remarkable trip over Hell (Inferno), Purgatory (Purgatorio), and Paradise (Paradiso). Under the direction of the ancient Roman poet Virgil and his lover Beatrice, he visits many historical and mythological characters in every sphere and observes the lifetime results of earthly misdeeds and virtues. Offering great insights into the nature of good and evil, free will, and divine justice, the road functions as an emblem for the soul's path toward God.
