We begin Series 4 as we follow Dante and Virgil as they come up to and ascend Mount Purgatory, a story dramatising what we do when we cleanse ourselves of the stains within us. Come along: the scenery is beautiful, the encounters are striking, the wisdom resonates. And we can do it together as we read/listen. In Canto 1 we meet the mysterious figure of Cato, their first encounter, the Guardian of the Gate.
