The Sword in the Stone: What the legend gets wrong

Everyone knows the legend. A sword, a stone, a boy who would be king.The problem is that nobody agrees on which story, which sword, or which stone. Also, the real sword in the stone is in Tuscany, not Camelot.

The sword in the stone is one of the most confused legends in Western culture: a thousand-year telephone game played by Welsh bards, French poets, Italian monks, a British novelist, and a team of Disney animators. By the time it reached your childhood TV screen, at least four different stories had been blended into one, the timeline scrambled by nine centuries, and the sword itself looked nothing like what Arthur would ever have carried.

Here is what actually happened.

The legend was built on a Romano-British commander

If King Arthur had a historical basis (and most modern historians are careful to say “if”), he was probably a post-Roman military commander active in late 5th or early 6th century Britain. No castles, no jousting, no chivalric code. The weapon of that world was the spatha or an early Migration Period blade, inherited from the late Roman military tradition: long, with a parallel profile and minimal guard. The knights-in-shining-armour aesthetic came much later, and so did the stone.

1136: The sword gets a name

Geoffrey of Monmouth’s Historia Regum Britanniae is where Arthur’s sword first appears in writing. Geoffrey calls it Caliburnus, forged in Avalon, carried by a king. No stone, no anvil, no test. Just a sword with a name and a mythological origin. Geoffrey was almost certainly making most of it up, and medieval readers largely knew it, but the book became one of the most copied texts of the Middle Ages regardless.

1200: The stone enters the story

The motif everyone actually remembers, the sword driven into an anvil on a stone, the rightful king proven by what he can pull out of it, appears for the first time in Robert de Boron’s French poem Merlin, written somewhere around the turn of the 13th century. De Boron did not get it from Geoffrey. He invented it, or borrowed it from somewhere we can no longer trace.

How King Arthur became European

Chrétien de Troyes had been building this world as well since the 1170s, writing for the court of Champagne. He is the one who gave Lancelot his impossible love for Guinevere, who sent Perceval stumbling toward the Grail without quite understanding what it was, who turned a collection of Welsh warrior tales into something that felt like it was about real people with real desires. The sword in the stone is nowhere in his pages, but the world that makes the sword meaningful is almost entirely his invention. Wolfram von Eschenbach read him, disagreed with him, and rewrote Perceval’s story in German as Parzival around 1210, darker and stranger, less interested in courtly elegance and more in what a man owes to God and to himself. Between the two of them, the Arthurian legend stopped being a British story and became a European one.

There is another detail that modern retellings consistently get wrong. In Sir Thomas Malory, author of Le Mort d’Arthur (1485) the sword Arthur pulls from the stone is not Excalibur. It breaks during a fight with King Pellinor. Merlin then takes Arthur to a lake, the Lady of the Lake surfaces, and hands him a different sword entirely. Two swords, two scenes, two separate moments. The conflation into one is a later simplification, and it stuck.

The version most of us grew up with comes from T.H. White’s The Sword in the Stone, published in 1938 and adapted by Disney in 1963. White was not interested in historical accuracy. His Merlin ages backward through time, his England is the kind that only great writers can build.

1963: The version most of us grew up with

In the 1963 Disney film, the sword in the stone is a classic late medieval arming sword: broad blade, curved crossguard, disc or spherical pommel. As a piece of design, it is inspired by several artifacts, but it belongs to a 14th to 15th-century context, not a 5th-century one.

As we said before, a historically plausible Arthurian blade would have been a spatha or an early Migration Period sword: a long, relatively parallel-sided weapon, a rounded tip, and an organic handle, very hard to find intact nowadays. Nothing like what we picture as “legendary”, with little of the dramatic triangular design we associate to “Excalibur”.

A pointed arming sword with these elegant proportions belongs to the medieval world, like Oakeshott sword types XIV, XV, XVI or XVIII . Disney depicted a sword from approximately 800 to 1000 years after Arthur supposedly lived.

And yet this is historically revealing. When de Troyes, de Boron, von Eschenbach wrote Arthur, they imagined him with the lens of their own time. When Disney studios animated the story in 1963, they used the sword that read most legibly as “legendary” to a mid-century audience. The legend has always been a mirror.

The real sword in the stone

A knight and a hill in Tuscany

While poets were building the Arthurian mythos, something happened in Tuscany that has never been fully explained.

Galgano Guidotti  was born in Chiusdino, a small town in the modern province of Siena. The son of a feudal lord, Galgano became a knight, and is said to have led a riotous life before his conversion. Following what the historical record describes as a vision, , he rode to the top of Montesiepi hill and drove his sword into a rock up to the hilt. The crossguard formed a cross. He knelt and prayed. He stayed on that hill as a hermit until he died in 1181, aged 33.

He was not claiming kingship. He was surrendering it. The gesture is the exact inverse of the Arthurian one, and that is what makes it interesting. The sword is still there.

What the science says

For centuries the sword was considered a probable fake. Then, in 2001, a team from the University of Pavia used neutron activation analysis and metallurgical forensics to confirm that the blade’s iron matched 12th-century forging, and the stone showed no sign of modern manipulation. Ground-penetrating radar also revealed a cavity measuring 2 by 1 meters beneath the sword, perhaps containing the body of San Galgano himself.

Arthur or Galgano: Who inspired whom?

Italian scholars argue that Galgano’s sword in the stone precedes the Arthurian motif. Robert de Boron’s poem, where the stone first appears, came decades after Galgano’s canonization. Some have suggested the round chapel inspired the Round Table, and that Galgano became Gawain.

The counterargument is equally credible: Cistercian monks who took over Montesiepi in 1218 may have placed the sword deliberately, borrowing Arthurian imagery to promote the cult of their new patron saint. Both legends were alive in the same decades, in cultures connected by the same trade routes and monastic networks. The honest answer is that we do not know which came first, and may never know.

What the Sword in the Stone taught us

Here is where historical record and our workshop meet: a critical study must be done when it comes to reconstruction.

Being a stylisation and an idealisation, the sword depicted in the 1963 animated film belongs aesthetically to the 14th and 15th centuries. The Oakeshott types XIV and XVIII offer in our opinion the best match: broad blades tapering strongly from the hilt, double-edged cutting swords designed to counter chainmail. One of the finest surviving examples of the type XIV is held at the Metropolitan Museum of Art in New York, accession 23367. It was this piece, with its broad fullered blade, inscriptions and bronze crossguard, that served as the foundation for our Aineias Arming Sword. The pommel carries words from Virgil’s Aeneid: “Here, too, virtue has its due reward.” Some say this could be a historicism, but it is such a fine example that we couldn’t help but give our own interpretation of it.

Another example consistent with this typology is preserved in the Musée de l’Armée in Paris, a French sword of the mid-14th century, inv. J PO 678: we were commissioned to reproduce it, and the Clementia Arming Sword was born.

Examples of Type XVIII can be found in museum collections, among them a sword from the Arsenal of Alexandria at the Met, accession 23189, and swords from the Castillon group, including this, sold at Bonham’s Auction house.

The sword of San Galgano belongs to a different chapter entirely. Being an Oakeshott type Xa, it is consistent with the late 12th century. To honour our Tuscan heritage, we gave our interpreation through the Galavant Arming Sword, made in our workshop some years ago.

This is the deeper lesson the sword in the stone has to offer a swordmaker: you have to pull harder than most people are willing to. The surface is never where the rewards are.

A Note From the Workshop

Every legend accumulates layers. The most cinematic version buries the older underneath it, and most people never think to look further. The sword is still in the rock. The manuscripts are still in the archives. The metallurgical reports exist. The museum catalogues are there for anyone willing to open them.

For a swordmaker, this is not optional. Every curve, every decision about a blade’s taper and profile has to come from somewhere real and applied to the modern standards. That means reaching past the Disney version, past the romantic retelling, past the comfortable image, and into the actual evidence. It is not always easy, but what you find when you get there is always worth it.

Galgano did not pull the sword out. He pushed it in, and walked away from everything he thought he knew. That, too, is how you get to the truth.
