“The commentaries on the Commedia also began stacking up at my bedside and on the bookshelf next to my chair in the den. There was Charles Williams’s The Face of Beatrice, Harriet Rubin’s Dante in Love, Yale scholar Giuseppe Mazzotta’s Reading Dante, and later the galleys for English Dantist Prue Shaw’s Reading Dante: From Here to Eternity. Most important of all, I began listening to the Great Courses audio lectures by Bill Cook and Ron Herzman, which made the poem come alive like nothing else.”
