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 As the book series progressed, many of those essays became outdated or were proven wrong.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

N.B.: Dates for this essay are based on the timeline in the Lexicon. Notes on sources from outside the canon are at the end. Sibyll Trelawney is named after an ancient prophetess from classical mythology—or, more accurately, she is named after a whole group of prophetesses from classical mythology. The name Sibyll was… Read More

 Introduction No, I don’t intend to predict the identities of the next several Ministers for Magic, but rather to present and discuss the various evidence available in Harry Potter canon on the relative ages of the seven Weasley siblings. Since the original version of this discussion, Rowling has, on her website, www.jkrowling.com, presented us… Read More
• Essay The Riddle of the Potions seldom gets the respect it merits. It is the last challenge faced by Harry and Hermione before entering the chamber where the Philosopher’s Stone is kept safely hidden in the Mirror of Erised. Usually when reading the book, we speed past the riddle, admire Hermione for solving… Read More

The name “Dobby” appears in A Fine Old Conflict, 1 Jessica Mitford’s memoir of her radical youth in 1950s America—and a book J K Rowling has almost certainly read. Rowling, as we know from interviews, admires Jessica Mitford—she even named her daughter after the left-wing political campaigner and journalist. “Dobby” Walker (no other… Read More

Not the least interesting thing about Harry’s possessions is that it is possible to make a virtually complete list of them. This is because he starts with nothing but the blanket he is wrapped in. His material poverty is contrasted with Dudley Dursley’s conspicuous consumption, both literal and metaphorical. Though the four books we… Read More

I do know that many people have theorized about how Muggle-borns get their Hogwarts letters (and take them seriously), or are taken to Diagon Alley for the first time, or how they are able to adjust. Even with Rowling’s recent comments on this topic, we’re still left with a lot… Read More

Luna is clearly Hermione’s mirror. I think Hermione’s rationalism, which is such an important part of the trio’s dynamic, has its downside: an unwillingness to leap before looking; a fear of the unknown. We’ve watched Hermione freeze up in just about every book because her studies haven’t provided her with the answer. Usually Ron and Harry have to pull/prod/jolly Hermione past… Read More

At turns exciting, suspenseful, horrific, unexpectedly funny, and in the end, tragic, OP35 (“Beyond the Veil”) brilliantly captures the chaos and confusion of battle. Harry doesn’t have time to fully comprehend everything going on around him, but we the readers have the luxury of going back and re-reading this chapter for new insights… Read More

(by Nik the Hermit, our “man in the street”) J. K. Rowling has stated many times that memories and “echoes” from her own childhood became part of the Harry Potter Books. Two well-known examples are: The use of the surname of her two friends from her early childhood, Ian and… Read More

After the events of book five, one can’t help but wonder whether Harry is really safe now in Privet Drive. Has the protection reached critical mass at this point, and are the risks beginning to outweigh the benefits? Obviously when Voldemort was Vapormort, and the most loyal Death Eaters were incarcerated in Azkaban, the protection held up very… Read More

At Nimbus 2003, several people asked if they could see my notes. It never occurred to me that anyone would be interested, but I was sort of flattered that they asked. So I figure that there might just be a few curious people out there who might want to see… Read More

Let us take a look at the mysterious, amazing Marauder’s Map. But first, let’s look at the castle. If you research castles on the Internet, you will see that Hogwarts is a castle of unprecedented (mammoth, huge, gigantic) size. You might find some castles that have towers that are 7 commercial stories high,… Read More

In order to speculate on and understand this character, we must begin, as in all things, at the beginning. The fecund Weasley family have more than enough children to run the whole gamut of human emotions and personalities; why bother even to create this last-born enigma and to make her a girl… Read More

There has been a lot of talk about who might come back as ghosts in the Harry Potter series. I don’t think Rowling will have anybody return as a ghost, because she is very aware that there are children reading this series who have lost or about to lose a… Read More

I am an astrologer, and I observed the types of astrology Trelawney and Firenze teach (and presumably practice) are two different types. Trelawney’s astrology is natal or genethiliacal astrology. It consists of personal birthcharts and what will happen when Mars and Saturn make an angle. As Parvati said, it has to do with individuals and their… Read More

I’ve just finished my third reading of OP. The Dursleys interest me in a way that I can’t fathom, but I feel the need to explain Petunia Dursley. OP opens our minds and Harry’s to the idea that Petunia had had more contact with, and understanding of, the wizarding world then she had hitherto pretended. From the small glimpse we… Read More
