Okey-dokey. Here we go: May 14 marks the birth date of great Italian poet, Dante Alighieri, and famed anthropophagus Hannibal reveals a deep love of Dante, both in 2001's Hannibal and Mads Mikkelsen's show. This may seem like nothing more than a literary curio in the world of blockbuster horror, but the choice is startlingly accurate for Hannibal Lecter.
Dante first appeared as a Hannibal theme in Thomas Harris's 1999 novel, Hannibal, where the eclectic cannibal lectures — appropriately — on "the matter of chewing in Dante."
Ridley Scott kept Hannibal's love of Dante, forming it into this marvelously tense, scene between Dr. Lecter (in the guise of "Dr. Fell"), Rinaldo and Allegra Pazzi in 2001's Hannibal.
A similar scene happens in TV's Hannibal, Season 3, Episode 1, "Antipasto," where Mads Mikkelsen's Hannibal schools an arrogant Italian with his knowledge of Dante.
The resultant intellectual smackdown is rather satisfying, and best expressed by this marvelous gif from ct101:
It's satisfying that both Ridley Scott and Bryan Fuller kept Hannibal's love of Dante in their respective adaptations of the Lecter story. Hopefully the Hannibal TV show will be granted a reprieve and this fascinating aspect of Dr. Lecter's personality can be explored further.
