Shortly after the Lexicon was created in 2000, the first essay appeared: The Limits of Magic by Caius Marcius. From that point on, the Lexicon’s collection of canon-based essays grew and grew. As the book series progressed, many of those essays became outdated or were proven wrong. However, they are all included in our collection as an archive of fan thinking and speculation during those exciting years. You can find all those essays, plus new ones as they get published, listed here. The following listing of essays is in reverse chronological order — the more recent essays are listed first.

The Hut-on-the-Rock holds a key place in the life story of Harry Potter.  It was here, on his eleventh birthday, that he encountered the world of wizardry for the first time since infancy. But where was it? The address on the letter brought by Hagrid in PS4 is not very helpful: Harry Potter, The Floor, Hut-on-the-Rock,… Read More

As part of our quest for the possible meanings of ‘hallows,’ Lexicon friend Bandersnatch kindly agreed to assemble some information for us. The result is an excellent essay which gives us some context for the new book’s title. Enjoy: The Grail Hallows and Harry Potter… Read More

Presented at Lumos 2006 Las Vegas, Nevada 29 July 2006[*] How wonderful it is that the second chapter of Harry Potter and the Half-Blood Prince is titled “Spinner’s End.” Wonderful, because, if read ironically, it refers not only to a place, but to Severus Snape’s fate, a rubric revealing that the… Read More

After walking—or rather riding—up the staircase to the Headmaster’s office, one knocks on the door, enters, and is greeted not only by the face of the Headmaster, or Headmistress, but by soft snores coming from the wall. We are first introduced to the Headmaster’s office, and the decorations it contains, in Chamber of Secrets (CS12). Here,… Read More

The newly released Black family tree, now revealed in its full glory, is the topic of considerable discussion and is a source of considerable information on the relatedness of the various pure-blood  wizard lines. Many familiar names show up on that tree, including Weasley (blasted off, of course). Sirius Black comments in Order of the Phoenix, “Molly and I are… Read More

Since the arrival of Half-Blood Prince on July 16th, 2005, Harry Potter fans have been endlessly searching for Horcruxes. We find ourselves repeating the Horcrux possibilities just like Harry does in Half-Blood Prince: “the cup, the locket, the snake, something of Gryffindor or Ravenclaw’s . . . .” (HBP30). Several Horcrux identity theories have been circulating, with claims ranging from Tom Riddle’s mouth organ to Gryffindor’s old toothbrush. After reading… Read More

The Hogwarts Express has been the subject of various essays exploring its nature and function. As has been plausibly noted elsewhere on this site, it isn’t really a steam engine, but rather a magical transportation device that mimics a Muggle equivalent in external form and function. This is consistent with the general trend in Wizard “technology,” which seems… Read More

Every living thing has genes that largely determine its appearance. Humans (magical or Muggle) look like humans because they have human genes; dogs look like dogs because they have dog genes; cats look like cats because they have cat genes. The set of genes that make up an individual person or dog… Read More

I read with interest the essay “Magic, Genes, and Pure Blood,” by glamourousgeek, being myself involved in research into the complex inheritance of magic, but I must take exception to the science expressed within it.[*] Even if the magic trait is inherited through Mendelian genetics (which does not quite… Read More

“One day,” said Hermione, sounding thoroughly exasperated, “you’ll read Hogwarts, A History, and perhaps that will remind you that you can’t Apparate or Disapparate inside Hogwarts.” (OP23) “Well, he [Dumbledore] can’t have Disapparated!” cried Umbridge. “You can’t inside this school—” (OP27) Quietly, tentatively, Harry spoke into the darkness. “Kreacher?” There was a very… Read More

  A pile of critical rubbish has been composting around J. K. Rowling [Editor’s Note: The link provided is to an archive of jkrowling.com, which was superseded by Pottermore.] and her Harry Potter books ever since they were discovered by young (and not-so-young) readers and became phenomenal best sellers. The charges, briefly, as these. (1)… Read More

Here in the Lexicon, there are multiple essays on Harry, Hermione, Ron, Ginny, Snape, physical locations, creatures, and practically anything else you can name. And yet there is not one essay about one person whose fate is tightly linked to Harry’s, and who has been moving gradually but inexorably towards a more important position in the books: Neville Longbottom. I think Neville becoming… Read More
