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 As the book series progressed, many of those essays became outdated or were proven wrong.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

Within the Harry Potter stories are many scenes that can be analyzed astronomically. As both an astronomer and a teacher, these interest me, and so I will present such analysis here. My goal is not to criticize Rowling when she is inaccurate in her astronomy (or, for that matter, to praise her when she… Read More

Where is the Burrow—Harry’s second home (his first is Hogwarts, of course, not Privet Drive!)? Ottery St. Catchpole The books give the Burrow’s location as just outside the village of Ottery St. Catchpole, but give no direct clues as to where this is. The similarity of the name to Ottery St. Mary, in Devon has… Read More

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

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
