The main thing I learned is that the best time to read (or reread) this classic is during Lent. Who knew?

Like the rest of the Commedia, the poem is meticulously structured. The three parts are the arrival at Mount Purgatory (the only landmass opposite the inhabited continents of the known Earth), then the climb up the mountain around the seven cornices of purification, then the allegorical pageant of the blessed in the Earthly Paradise. Unlike the descent into Hell, Dante and Virgil complete their ascent over the course of a few days after Easter AD 1300, and because they may not make upward progress while the Sun is down, there are enforced rest (and dream) periods. This time when Dante interviews the souls they have an orientation toward Heaven; they are already saved, and submit to their trials voluntarily, as a sort of ultimate self-improvement. The stories are sometimes quite similar to what we saw in Inferno, with the addition of a sincere repentance and absolution at the end. At the same time, Dante the pilgrim is changing, having his sins erased from his brow as he grows lighter and lighter on his trip up the mountain. The way Dante understands what he sees when he arrives in Eden is Scholastic, not psychological, and it takes a fair amount of exertion to get into the proper frame of mind to appreciate the symbols and allusions packed into these scenes. This kind of work is not for everyone, probably, but there are moments of great beauty for the reader who can make the journey.
