Cerberus: Circle 3, Inferno 6   A three-headed dog who guards the entrance to the classical underworld. In the Aeneid Virgil describes Cerberus as loud, huge, and terrifying (with snakes rising from his neck); to get by Cerberus, the Sybil (Aeneas' guide) feeds him a spiked honey-cake that makes him immediately fall asleep (Aen. 6.416-25). Look at Dante's related but very different version of Cerberus in Inferno 6.13-33. How has Dante transformed him to fit the role of guardian in the circle of gluttony? How does Cerberus himself shed light on Dante's conception of the sin? Verses 28-30, describing the actual experience of a dog intent on his meal, exemplify Dante's attention to the real world in his depiction of the afterlife.
