Last canto ended on a cliffhanger, with Dante & Virgil barred from the City of Dis. Now, Virgil reports that reinforcements are on their way. Then he mentions his first trip from Limbo into Hell, back when he was newly late (thus filling in the backstory since his death in 19 BC). His anecdote's interrupted, however, by an attack from the Furies & Medusa (described only via sound—Dante doesn't see her, of course)! Then a heavenly angel appears, scattering the damned & storming the gates. It's thrilling! Inside, Circle #6: a traditional hellscape burns the souls of heretics.
