Inferno: Canto 24 - The Den of Snakes
THE DEN OF SNAKES In this canto, Dante and Virgil finally make it out of the sixth subring of the 8th circle. As they cross the next bolgia, a disgruntled voice draws them down to take a closer look. They discover the seventh subring is full of snakes and thieves. Our travelers speak with one of these thieves, a political opponent of Dante's, who tells them about his greatest crime and offers the pilgrim a discouraging prophecy.
