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 As the book series progressed, many of those essays became outdated or were proven wrong.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.

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.

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has been composting around J. K. Rowling [Editor’s Note: The link provided is to an archive of jkrowling.com, which was superseded by Pottermore.]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

After thinking carefully through the various factors involved, I cannot help but conclude that the most logical scenario, based on all the available evidence, is that Harry is a Horcrux. I will structure this essay in four sections. First, I will discuss the background. Second, I will discuss the evidence indicating that Harryis a Horcrux. Read More

Although Spinner’s End is probably not a real place in a real town, it’s reasonable to assume that it’s in an imaginary town in an area where towns of that type are found—just as Little Whinging is an imaginary town, but of a recognizably Surrey type. An argument has been made Spinner’s… Read More

We are just two years or less from reaching the end of the Harry Potter series and many essential questions have been answered, either by the books themselves, by J.K.

Introduction One of the most intriguing ideas in Harry Potter and the Philosopher’s Stone is that Professor Dumbledore set up events so that Harry would try and stop the theft of the Philosopher’s Stone by Voldemort. Many events in Harry’s first year seem to indicate this: his dealings with Hagrid, being given his father’s Invisibility Cloak (twice), his discovery of the Mirror of Erised, and his detention in… Read More

Although I am aware — reluctantly aware, but still aware — that Harry Potter is a fictional character, the fact remains that he has a birth date. Any person, real or otherwise, with a birth date also has an astrological birth chart, and Harry is no exception! In analyzing Harry Potter’s chart… Read More

The Harry Potter books have been the subject of much religious debate after fundamentalist Christians warned parents against the books, deeming them pro-witchcraft and consequently anti-Christian. Some Muslims, on the other hand, have banned the books for the entirely opposite reason, claiming they are poorly concealed Christian propaganda. Surprisingly however, the… Read More

Magic in the Harry Potter universe is as far as we know considered to be supernatural, and has as little to do with science as ghosts and flying broomsticks. However, the fact that magic runs in families means that it is a hereditary trait. Add to that the exceptions of half-bloods, Muggle-borns and Squibs and the temptation to analyze… Read More
