In this lecture we discuss Circles Four and Five of Dante's Inferno. Specifically we (a) consider Plutus, Ciacco, and the place of Fortune among the avaricious and prodigal; (b) we then consider the fifth circle, its division into anger and sullenness (sulkiness/resentment), and meet Phlegyas as we cross (c) the River Styx, the second of four rivers in Dante's "Inferno" and end with an exciting scene between Virgil, Dante the Pilgrim, and Filipo Argenti.
