Summary
A specific moment in theHarry Potterbooks always struck me as odd, but I only recently realized how important it was. While Voldemort’s resurrection inHarry Potter and the Goblet of Firewas clearly pivotal to the overall series, I see now that it was the moments that really got interesting. Author J.K. Rowling used the duel between Harry and Voldemort to reinforce the structure of Harry’s story, initiating a significant shift that served as a catalyst for everything that came after. To see what I mean, it’s essential to understand the chiastic structure of theHarry Potterbooks.
Chiasmus is a literary device in which words or concepts are repeated in reverse order. In the case of theHarry Potterseries, the first three books are reflected back by the last three books, withGoblet of Fireserving as a pivot or axis point. After the fourthHarry Potterbook, the story of the fifth parallels the third, the sixth reflects the second, while the seventh brings back concepts and themes from the first. This means that, afterGoblet of Fire, Harry’s story started repeating itself in reverse order, andthe starting point of chiasmus was one highly clever event.

I Only Just Realized The Coolest Thing About The Harry Potter Series After 17 Years
The Harry Potter series follows a clever structure that makes the events of Harry’s story even more impactful, and I can’t believe I never noticed.
“Priori Incantatem” Is Deeply Important To The Structure Of The Harry Potter Books
This Harry Potter Moment Begins The Series' Chiastic Structure
Once I realized that J.K. Rowling’sHarry Potterseries used chiasmus, I became obsessed with understanding howGoblet of Firefit. Sure, it was the middle point in which the series folded over on itself, but there had to be more to it than that. I found my answer inGoblet of Firechapter 34, “Priori Incantatem.” This is the chapter in which Harry and Voldemort face off for their duel. Their wands connected, and a bead of light slid down the beam until it joined with the Dark Lord’s wand, and the weapon began to regurgitate all the magic Voldemort had recently performed. Later, Dumbledore called this phenomenon Priori Incantatem:
“Priori Incantatem,” he muttered.
His eyes gazed into Harry’s and it was almost as though an invisible beam of understanding shot between them.
“The Reverse Spell effect?” said Sirius sharply.
“Exactly,” said Dumbledore. “Harry’s wand and Voldemort’s wand share cores. Each of them contaions a feather from the tail of the same phoenix. This phoenix, in fact,” he added, and he pointed at the scarlet-and-gold bird, perching peacefully on Harry’s knee.
“My wand’s feather came from Fawkes?” Harry said, amazed.
“Yes,” said Dumbledore. “Mr. Ollivander wrote to tell me you had bought the second wand, the moment you left his shop four years ago.”
“So what happens when a wand meets its brother?” said Sirius

“They will not work properly against each other,” said Dumbledore. “If, however, the owners of the wands force the wands to do battle . . . a very rare effect will take place.One of the wands will force the other to regurgitate spells it has performed—in reverse. The most recent first . . . and then those which preceded it. . . .”
I can’t help but feel a thrill when reading Dumbledore’s final lines here. What the headmaster is describing while explainingPriori Incantatem is chiasmus, and in the world of literature, this can be no coincidence. When Harry and Voldemort’s wands connected, shadows of the last handful of spells the Dark Lord had cast were forced from his wand in reverse order. However, this wasn’t all. It’s as if the magical effect ofPriori Incantatem seeped out ofHarry Potterand into the real world, causing the story itself to begin to repeat in reverse order as well.

Why The Chiastic Structure Of Harry Potter Is So Genius
This Literary Device Enhances The Magic Of Harry Potter
Harry Potterhas become such a massive franchise that it’s easy to forget that the books carry literary significance. Harry’s adventure is more than just a fun story. There is a great deal within these pages that could be analyzed for generations to come. Rowling’s use of chiasmus is a prime example. By doubling back on itself and repeating the concepts of the first three books in reverse order, theHarry Potterbook series featured a superb rise and fall. There’s an intriguing familiarity in the second half of Harry’s story, butthe reverse action meant that expectations were used against the reader.

Axis Point
The second half of theHarry Potterseries revisited moments, characters, and features that readers had already moved on from. Things like Harry’s first Golden Snitch, the Deluminator, Tom Riddle’s diary, andthe Vanishing Cabinetbecame important again. Characters like Snape, Draco, and Sirius, whose morality had already been established in the first three books, were explored again under a far stronger microscope, revealing more complexity.All of this served the greater theme ofHarry Potter—that nothing is as black and white as good and evil. Everything is worth a second look, and it all starts with thisGoblet of Firemoment.
Other Ways That Goblet Of Fire Was The Most Important Book Of The Series
Goblet Of Fire Set The Stage For Harry’s Ending
I first readHarry Potter and the Goblet of Fireover 20 years ago, and while it was exciting, I now know that there was so much that my younger self missed. Upon reflection, I feel that this was one of the most pivotal books of the series. Not only is this the book in which magic seeped from the story into the real world, initiating the chiastic structure that makes the flow ofHarry Potterso impactful, butthis is also when the truth about Harry and Voldemort is brought to the surface.
Harry was only the Chosen Onebecause of Voldemort’s own actions, and the events ofGoblet of Firerevealed how the Dark Lord simply couldn’t learn his lesson. Voldemort marked Harry as his equal by attempting to kill him as a baby, and he repeated this mistake by using the boy’s blood to resurrect a body when any of his enemies would have worked. In doing so, he takes Lily Potter’s protection into his own body, ensuring that he can never kill Harry.
All Dumbledore and readers had to do from Priori Incantatem onward was sit back and enjoy the rest of the story—in reverse order, of course.
InGoblet of Fire, Dumbledore has a brief look of “triumph” on his face when Harry tells him what Voldemort has done. Of course, I didn’t know what this meant, nor did I even remember that it had happened, until I reread the fourth book after readingDeathly Hallows. It was one of those fun, subtle secrets that proved that the story ofHarry Potterwas laid out from the very beginning. The events ofGoblet of Firesealed Harry and Voldemort’s destiny. All Dumbledore and readers had to do from Priori Incantatem onward was sit back and enjoy the rest of the story—in reverse order, of course.
