After Inferno, the Divine Comedy resumes at the foot of Mount Purgatory, where only keys of gold and silver can allow passage to its seven terraces. Here, penitence provides a path to love, redemption and divine grace. Glorious jeweller’s castings trace Dante’s ascent as, one by one, he is rid of his sins. At a summit clad in cloisonné, Earthly Paradise and the cleansing waters of the river Lethe await.
