After reading parts of Aeneid, I couldn't help but recognize similar uses of mythological allusions in more recent novels, such as the Harry Potter series. It contains many different characteristics of mythology, such as centaurs, dragons, griffins, basilisks, phoenixes, and many more. Perhaps the most obvious is Hagrid's "pet," Fluffy. Basically the 20th century version of Cerberus, Fluffy embodies every aspect of the original Cerberus. Both are three-headed dogs, that much is obvious. They are the guardians of some "gate" (whether that be the gate to the Underworld, or the trapdoor leading to the Sorcerers Stone). In both stories they are, of course, "defeated" (lulled to sleep) through music - Fluffy through the enchanted harp, and Cerberus through Orpheus's lyre.
