'The legend is so strong': The truth about Nicolas Flamel and the philosophers' stone

The myth of Nicolas and Pernelle Flamel, medieval Parisians said to have made gold with a 'philosopher's stone', sparked a centuries-long obsession. Now a new examination of Flamel's centuries-old will has shed a light on how the legend emerged.

For 600 years, writers, artists and scientists have been fascinated by the legend of Nicolas and Pernelle Flamel: a medieval Parisian couple who were said to have created the mythical philosophers' stone, a mysterious substance that supposedly turned ordinary metals into gold.

Flamel, a real person who was born in the 1330s and died in 1418, in fact never had anything to do with the practice of alchemy, the ancient, mystical tradition which aimed to create gold, cure all diseases and bring immortality.

Still, Flamel's mythical reputation as an alchemist inspired generations of scientists and writers including Isaac Newton, Victor Hugo, and JK Rowling, who mentions Nicolas and Pernelle Flamel in Harry Potter and the Philosopher's Stone.

This autumn, the will of Nicolas Flamel is on public display for the first time at a new exhibition at the Musée de Cluny in Paris. Stored in a Parisian hospital archive for centuries, the document sheds a new light on how he ended up being revered as an alchemist, says Maëlys Bitouzet, one of the curators of the exhibition. "They were documents that had never been studied," until the museum evaluated them in 2024, says Bitouzet.

The quest to uncover why Flamel became known as an alchemist also sheds light on the enduring appeal of this ancient tradition, and its sometimes-overlooked place in the history of science.

The first alchemical writings appeared around 2,000 years ago in ancient Egypt. Through copies and translations, they spread to Europe in the 12th Century with the Islamic Conquest. The word "alchemy" is thought to be an Arabic-Greek hybrid, with an unclear meaning – it could refer to melting or to Egypt. Alchemy used routes which we now know are not scientifically viable, though some of the elusive aims have since been achieved in very fleeting, experimental set-ups.

Throughout its history, alchemists wrote about their efforts to create an enigmatic, powerful stone.

"The earliest reference to 'the stone of the philosophers' is in the 7th Century, in a Byzantine text," in the eastern Mediterranean, says Matteo Martelli, a professor in history of science at the University of Bologna in Italy and expert on ancient alchemical texts. "'The philosophers' were what alchemists called themselves."

The concept of the stone appears even earlier, in a text dating from the 1st Century BC, where the author "refers to a stone that is not a stone", says Martelli. "There is this cryptic way of talking about this stone, which was later called the philosophers' stone," he adds, noting it wasn't literally a stone, but came in different forms such as a powder or liquid.

The stone was meant to turn other metals into gold or silver, not necessarily for personal gain, but as a way of perfecting nature, says Martelli. In medieval Europe, an additional belief grew that the stone would bring health benefits and even immortality.

This is where Flamel enters the history of alchemy.

Traces of Flamel's real life are dotted around Paris, including his tombstone, which is a visitor magnet at the Musée de Cluny, France's National Museum of the Middle Ages. "In the [Harry Potter] book, Flamel is an alchemist, a sorcerer, so it's surprising to people that there's a real tombstone, and that Flamel was a real person," says Bitouzet.

In the late 15th Century, some 50-75 years after his death, an alchemical text known as Le Livre Flamel (The Flamel Book) was published in France – the first alchemical manuscript published under the name "Flamel". While it was actually by an anonymous author, not the real Nicolas Flamel, it became a huge success.

"[Le Livre Flamel] was very popular, it was re-copied, and then people really began to associate it with [the real] Nicolas Flamel," says Bitouzet. Over the centuries, other writings appeared under his name, sometimes including detailed real facts about Nicolas and Pernelle Flamel's life in Paris, such as where they had lived.

The first Livre Flamel, from the late 15th Century, describes a step-by-step alchemical procedure that results in a liquid, Bitouzet says. According to the book, immersing lead into this liquid transforms it into gold.

"It talks about the theory of alchemy, how one can help metals reach a purer state. And then it really gives you the practical recipe [for a philosophers' stone], as if Flamel is giving you little tips to make your philosophers' stone a success," says Bitouzet.

Martelli, who has seen the original, 15th-Century Livre Flamel, notes that some of the procedures and ingredients are the same as those in the much older, Eastern manuscripts. In other words, while the attribution to Flamel was fake, the recipe did tap into genuine alchemical history.

So why did someone copy ancient alchemical instructions, then publish them under the name of a real, dead person? Flamel's will, and other documents and artefacts, have shed a new light on this mystery.

The last will and testament and related documents had been kept in the archive of the Hôpital des Quinze-Vingts in Paris, which specialises in eye disease and dates to 1260. Flamel was one of the hospital's benefactors and included it in his will. 

"They were documents that had never been studied," until the museum evaluated them in 2024, says Bitouzet.

Other historical records and monuments already painted a picture of Flamel as a wealthy property owner who donated to churches and charities. But the newly studied documents show that his investments and impact were far bigger than had previously been assumed, says Bitouzet.

"He really had a real-estate empire," says Bitouzet. "Before [the discovery of the will and related documents], we vaguely knew that he owned a lot of real estate, but we didn't know exactly what he owned and where these houses were." 

Flamel was the creditor of hundreds of property owners in and around Paris, and himself owned around 10 houses, according to the documents, Bitouzet says. His will stipulated various charitable donations and shows him making detailed arrangements for joint Masses to be read for him and his wife after his death (Pernelle had died earlier than him). These Masses continued for centuries, until the eve of the French Revolution in 1789.

After Flamel's death, a legal battle over his inheritance put his wealth in the spotlight. This combination of fame, wealth and philanthropy could explain why people thought Flamel was an alchemist, Bitouzet says.

"A man who was rich, who was not aristocratic, but who had a high social standing – people found that strange," Bitouzet says. Alchemy – seen then as a way of doing God's work – could have explained his wealth, charitable donations and seemingly blessed life, she adds.

As early as the 1700s, some questioned whether Flamel was really the author of the texts in his name, but it didn't stop the interest in him. Real-life reminders of Flamel may have helped keep the legend alive. A house built by the Flamels in 1407 and offered as shelter to the poor stands in the Rue Montmorency to this day – it's one of the oldest houses in Paris.

Pernelle is also mentioned in the writings published under Flamel's name as a virtuous woman who worked with Nicolas, and who would have also been able to create a philosophers' stone if she had wanted to, says Bitouzet.

Martelli points out that publishing texts under the names of famous people, a phenomenon called pseudo-epigraphy, was common from the earliest days of alchemy. "Pseudo-epigraphy is a feature of the alchemical tradition," he says. "So what happens with Flamel is a mechanism that we can see in many moments in the history of alchemy. It's just to make a text more authoritative, more legitimate."

The broader quest to produce the philosophers' stone did lead to scientific breakthroughs. For example, phosphorus was first isolated in the 17th Century by a German alchemist trying to find the philosophers' stone. 

Today, though, the main reason Flamel continues to fascinate people is his immortal life in books and art, says Bitouzet. "The legend of Flamel is so strong that people don't want to give up on it, even when they know he wasn't an alchemist," she says.
