Dante is portrayed as undertaking an epic voyage,having Virgil to lead him through the Inferno (all-consuming fire such as that 'found' in Hell.) After dealing with some rather more prosaic matters, they find a capacious cave, and decide to plumb its depths. They find themselves in a dream landscape which is night when the outside world is still in sunlight. All around the verdant lush countryside are the ghosts of dead ancestors. The original hero of the myth (Aenas) follows his guiding helper through numerous rivers of this hell, across one called the Styx. The original ferryman was called Charon.
