Hermione's Ancient Runes class mixes real Elder Futhark with invented pictograms. We break down which Harry Potter runes come from actual historical futhark and which Rowling made up.
Hermione Granger is the only one of the three main characters in the Harry Potter series who takes Ancient Runes at Hogwarts. She studies it through to N.E.W.T. level, uses a Time-Turner in her third year to fit the class around her other subjects, and still manages to confuse two runes on her O.W.L. exam. Those two runes, ehwaz and eihwaz, are not invented. They are real Elder Futhark characters that were carved across Northern Europe for roughly seven centuries.
That detail is the hook for anyone who cares about real writing systems. J.K. Rowling borrowed from genuine runic tradition in some places and invented pictograms in others. The Pensieve carries "modified Saxon runes." The Tales of Beedle the Bard uses something closer to circles and little pictures. This post separates the real futhark from the fiction, names the sources, and points you at tools where you can experiment with related scripts. If you want to play with Elvish and Dwarvish scripts from another famous fantasy setting, try our Tengwar and Cirth translator.
Ancient Runes is an elective course at Hogwarts School of Witchcraft and Wizardry. According to the Harry Potter Lexicon's entry on Ancient Runes, the class is taught by Professor Bathsheda Babbling. Hermione is the only main character to take it. Ron and Harry opt for Divination instead, which is a choice that tells you something about how the series frames academic discipline versus gut instinct.
Rowling treats Ancient Runes as a serious scholarly subject. Hermione uses a reference work called Spellman's Syllabary to translate her homework. Bill Weasley works as a Curse-Breaker for Gringotts, a job that involves deciphering runic curses in Egyptian tombs. The implication is that runes are not just a dead alphabet. They are a working magical language tied to real danger and real money.
The Time-Turner detail matters for the timeline. In Harry Potter and the Prisoner of Azkaban, Hermione is given a Time-Turner by the Ministry of Magic so she can attend Ancient Runes at the same hour as several other classes. The device is regulated under Ministry rules, and its use is restricted. That a student needs time manipulation just to fit the course load tells you how demanding the subject is supposed to be.
The most concrete link between Harry Potter and real runes is the O.W.L. exam mistake. Hermione confuses ehwaz and eihwaz. Both are genuine Elder Futhark runes.
The Elder Futhark on Wikipedia is the oldest form of the runic alphabets, used across Northern Europe between roughly the 1st and 8th centuries CE. It has 24 runes, each with a name and a meaning. The full set is fehu, uruz, thurisaz, ansuz, raidho, kenaz, gebo, wunjo, hagalaz, nauthiz, isa, jera, eihwaz, perthro, algiz, sowilo, tiwaz, berkano, ehwaz, mannaz, laguz, ingwaz, dagaz, and othala.
ehwaz is the 19th rune. Its name means "horse" and by extension "partnership," since horses were paired for pulling. eihwaz is the 13th rune. Its name means "yew tree" and by extension "defence," because yew wood was used for bows. The shapes are similar enough that a stressed student could mix them up. ehwaz looks like an M, and eihwaz looks like a vertical staff with a diagonal branch. Rowling got the semantic distinction right, which suggests she did at least some homework on real futhark.
For a named scholarly source on this, Ralph Elliott's book Runes: An Introduction (Manchester University Press, 1959) remains a standard reference. Elliott catalogs the Elder Futhark inscriptions found in Scandinavia and the Continent and gives the phonetic and semantic values for each rune. The ehwaz/eihwaz pair he describes matches what Rowling uses. The runic characters themselves are now encoded in the Unicode Standard in the Runic block, U+16A0 to U+16FF, which was added in Unicode 3.0 (September 1999). That block is what lets fonts render ᛖ (ehwaz) and ᛇ (eihwaz) in a browser today.
The Pensieve is the bowl Dumbledore uses to examine memories. In the books, its rim is carved with runes that Pottermore and J.K. Rowling's supplementary writings describe as "modified Saxon runes." The in-universe dating places them around the Viking invasions, circa 500 AD, which is a bit early for what a historian would call the Viking Age (that conventionally starts around 793 AD with the raid on Lindisfarne). But the intent is clear. These are meant to look like Anglo-Saxon or early medieval runic carving.
The visual style is angular. That is historically accurate for runes carved into stone and wood. Curves are hard to carve with a straight blade, so real runic inscriptions favor straight strokes. The Elder Futhark and its later descendants, the Younger Futhark and the Anglo-Saxon Futhorc, all share this angular quality. The Anglo-Saxon Futhorc expanded the Elder Futhark to as many as 33 runes to cover Old English sounds, and it was used in England from roughly the 5th to the 11th centuries. If you want to see how angular a real runic script looks side by side with another carved ancient script, compare it with our Linear B translator, which renders the syllabic script used by Mycenaean Greek scribes on clay tablets.
The Tales of Beedle the Bard is a children's book within the Harry Potter universe. Dumbledore bequeaths his copy to Hermione in Harry Potter and the Deathly Hallows. The book is written in ancient runes, and Hermione has to translate it. Her translation reveals the Tale of the Three Brothers, which is the origin story for the Deathly Hallows symbol and the three objects (the Elder Wand, the Resurrection Stone, and the Invisibility Cloak).
Here is where Rowling departs from real futhark. The runes in Beedle the Bard are described and drawn as pictograms. They use circles, lines, and small pictures rather than the angular letterforms of the Elder Futhark. They do not map neatly onto the 24-character futhark. In the real published edition of The Tales of Beedle the Bard (2008), the illustrations show a script that looks more like a personal cipher or a stylized symbol set than a historical runic alphabet.
This is a reasonable creative choice. A children's storybook inside a fantasy world should not look like a Norwegian memorial stone. Rowling needed something that felt old and magical without requiring readers to learn a real alphabet. The tradeoff is that you cannot "translate" Beedle runes the way you can translate a Caesar shift or a simple substitution. There is no published key. Hermione's translation work is treated as a plot device, not a solvable puzzle for the reader.
The honest answer is that Harry Potter runes are a hybrid. The named runes ehwaz and eihwaz are real Elder Futhark. The Pensieve's "modified Saxon runes" are a fictionalized version of real Anglo-Saxon runic tradition. The Beedle the Bard script is invented and does not correspond to any historical futhark.
This puts Harry Potter in a different category from Tolkien's Cirth, which is a constructed runic alphabet with a published letter-by-letter mapping to English. Tolkien designed Cirth so that fans could actually write in it. Rowling did not design a decodable runic system for Harry Potter. The runic elements are atmosphere and plot hooks, not a puzzle the reader is expected to solve.
That said, the real Elder Futhark is fully decodable, and it is a good first stop if you want to understand where Rowling's borrowings come from. The runic block in Unicode (U+16A0 to U+16FF) gives you the characters. Elliott's Runes: An Introduction gives you the history. And if you want to experiment with a related ancient script that is also carved and angular, the Egyptian hieroglyphics translator lets you convert text into the script that Bill Weasley would have been dealing with in those Gringotts tombs.
If you are building a puzzle or a CTF challenge with a runic theme, Harry Potter is a mixed source. You can safely use ehwaz and eihwaz as real Elder Futhark runes. You can reference the 24-rune futhark order as a substitution key. What you should not do is treat the Beedle the Bard pictograms as a standard alphabet, because no standard exists for them.
A cleaner approach is to build your puzzle on the real Elder Futhark and use the Harry Potter framing as flavor text. Give players the 24 runes, let them map runes to letters, and hide the key in the environment. That is exactly the kind of substitution puzzle our Tengwar and Cirth translator is built for, and the same logic applies to any fixed substitution script. The difference is that with real futhark you have a historical basis to cite, which makes the puzzle feel grounded rather than arbitrary.
One caveat. The Elder Futhark has 24 runes and English has 26 letters. Any substitution mapping requires you to merge two letter pairs or add extra rune forms. Rowling sidesteps this by not committing to a full mapping. You do not have that luxury if you want a solvable puzzle.
Partly. The runes ehwaz and eihwaz that Hermione confuses on her O.W.L. exam are real Elder Futhark runes. The Pensieve's 'modified Saxon runes' are based on real Anglo-Saxon runic tradition. The script in The Tales of Beedle the Bard is invented and does not correspond to any historical futhark.
The Elder Futhark is the oldest form of the runic alphabets, used across Northern Europe between the 1st and 8th centuries CE. It has 24 runes, each with a name and meaning. It is encoded in the Unicode Standard in the Runic block, U+16A0 to U+16FF, added in Unicode 3.0.
Professor Bathsheda Babbling teaches Ancient Runes at Hogwarts. Hermione Granger is the only main character to take the class, studying it through to N.E.W.T. level and using a Time-Turner in her third year to attend the lessons.
ehwaz is the 19th Elder Futhark rune and means 'horse' or 'partnership.' eihwaz is the 13th rune and means 'yew tree' or 'defence.' Their shapes are similar, which is why Hermione confuses them on her O.W.L. exam. Both are real runes, not invented by Rowling.
Not with a real-world key. The Beedle the Bard script is drawn as pictograms with circles and lines and does not map onto the Elder Futhark or any published alphabet. Hermione's translation is a plot device, not a solvable cipher for the reader.
