Cerberus appears in [[Dante's Inferno]], guarding the third circle of [[Hell]] rather than the entire underworld. This is the circle of [[gluttony]], and Cerberus is used to personify uncontrolled appetite.
Fluffy, the giant three-headed dog mentioned in ''[[Harry Potter and the Sorcerer's Stone]]'', resembles Cerberus. Both Fluffy and Ceberus are lulled to sleep by music. <ref>[http://www.nationmaster.com/encyclopedia/Cerberus Cerberus], NationMaster.com, Accessed October 30, 2008</ref>
