The Mona Lisa is the most famous painting on the planet by a distance that is hard to overstate. It draws millions of visitors to the Louvre annually, and most of them see it as a small rectangle behind glass over a crowd of raised phones.
The usual assumption is that this fame is the natural verdict of art history — that the painting is simply so extraordinary that it rose to the top. Leonardo was a genius, the portrait is a masterpiece, and the world eventually agreed.
That is not what happened. The painting was a well-regarded work by a revered artist, admired within the art world and by informed visitors, and it was not the singular global icon it is now. When it entered the Louvre in 1797 it hung on a wall with a number of other paintings, not isolated in a spotlight.
What made it a household name was a theft. Here is how a petty crime in 1911 created the most famous picture in the world.
The Monday Morning
On Monday 21 August 1911, the Louvre was closed to visitors. Three men left the building that morning, one with something under his jacket.
They were Vincenzo Peruggia, an Italian handyman who had worked at the museum, and the brothers Vincenzo and Michele Lancelotti. Accounts of the method differ in detail: some describe the men concealing themselves overnight in a storeroom near the Salon Carré, the gallery where the painting hung; others describe Peruggia simply entering through the workers’ door wearing the white smock all employees wore.
Either way, the execution was not sophisticated. Peruggia took the painting off the wall, removed it from its frame in a nearby stairwell, put it under his smock and walked out.
He was well placed for it. He was a familiar face, an odd-job man who had worked with the museum’s collection and had helped construct the protective glass frame for that very painting.
And then nothing happened for a day. Because the museum routinely took paintings off the walls to photograph them, the empty space attracted no alarm. The disappearance went unnoticed for roughly 28 hours.

The Sensation
Once the theft was recognised, the reaction was extraordinary and immediate. The Louvre closed for a week. The scandal filled newspapers across Europe and beyond.
The historian and writer James Zug summarised the effect neatly in an NPR interview marking the centenary: the Mona Lisa became an incredibly famous painting, essentially overnight.
The mechanism is worth understanding, because it is the heart of the story. Newspapers reproduced the image constantly — on front pages, in wanted notices, in speculation about where it had gone. People who had never set foot in a museum saw the face repeatedly for two years. The empty wall itself became an attraction, with visitors queueing to look at the space where the painting had been.
Conspiracy theories arrived immediately, as they do. Some suggested the theft was a hoax; others that the French government had staged it to distract public attention from unrest elsewhere.
The investigation was not the Louvre’s finest hour either. An inventory conducted at the time reportedly found that over 300 canvases were missing, and a contemporary cartoon depicted patrons casually walking out with artworks under their arms.
Two Years in a Trunk
Peruggia, meanwhile, had done almost nothing with it. The painting spent the entire period in France, in a one-room apartment on the outskirts of Paris, hidden in a wooden trunk with a false bottom.
The heist had generated so much attention that selling it became impossible, so the 29-year-old simply waited for the noise to subside.
The police interviewed him twice as a former Louvre employee and never treated him as a serious suspect. Questioned in November 1911, he said he had learned of the theft from the newspapers, and explained his lateness to work that August Monday by saying he had drunk too much the night before and overslept. That was accepted.
Then, after roughly two years, he tried to sell it. Writing under the name Leonardo Vincenzo, he contacted an art dealer in Florence, Alfredo Geri.
Geri was cautious. He arranged to view the painting alongside the director of an Italian gallery, and the two confirmed it was real, played along, and contacted the police. Peruggia was arrested.
Patriotism, or Something Like It
His stated motive was national. He claimed he had taken the painting to return it to Italy, believing it had been looted from there by Napoleon.
That belief was mistaken. Leonardo brought the painting to France himself in the sixteenth century, at the invitation of the French king, and it was acquired legitimately.
Whether patriotism was the whole truth is a fair question — he did, after all, attempt to sell it — but it played extremely well in Italy. Peruggia was tried, convicted, and served a short sentence, and there was considerable sympathy for him in his home country.
Before returning to Paris, the painting was exhibited in Florence, Milan and Rome to enormous crowds. It came back to the Louvre under a further shower of publicity. In the first two days after it was rehung, more than 100,000 people came to see it.
Why the Theft Worked So Well
The transformation is a clean case study in how modern fame is manufactured, and several factors compounded.
Absence is a better story than presence. A painting on a wall is not news. A painting that has vanished from the most famous museum in the world, with no suspect and no ransom, is a mystery that sustains coverage for two years.
Mass reproduction did the rest. The theft coincided with newspapers that could print photographs cheaply and distribute internationally. The image circulated far beyond anyone who might visit a gallery.
Then there was the return, which supplied a second wave of coverage and a triumphant ending — a narrative arc rather than a single event.
And crucially, fame is self-reinforcing. Once enough people knew the painting was famous, its fame became the reason to see it. Visitors came because it was the stolen Mona Lisa, then because it was the famous Mona Lisa, and each visit confirmed the premise.
None of this means the painting is unworthy. It is a truly remarkable work by one of history’s most inventive minds, and specialists admired it long before 1911. The point is narrower: artistic merit alone did not produce the level of global recognition it now has. An unlocked door and a slow news cycle did a substantial part of the work.
The Painter Nobody Suspected
One footnote to the case has become better known than most of the investigation, and it says something about how the police approached it.
In the confusion of the first weeks, with no leads and enormous public pressure, the authorities questioned a young Spanish painter then living in Paris. He was brought in because of a connection to stolen artefacts from the Louvre — statuettes that an associate had taken from the museum previously and that had passed through the painter’s hands.
The painter was Pablo Picasso, then in his late twenties and not yet the figure he would become. He was questioned and released, and had nothing to do with the theft.
The episode is telling in two ways. It shows how thoroughly the Louvre’s security had failed before 1911, since objects had already been walking out of the building. And it shows the investigation reaching for anyone with a plausible connection rather than the far simpler answer sitting in its own employment records — a man who had worked on the painting’s frame and lived a short distance away.
What It Should Change About How You Look at It
There is a practical takeaway, and it applies well beyond one painting.
The things we treat as obviously, self-evidently the best are often the things that had a story attached at the right moment. Merit gets a work into contention; something else usually decides which of the many worthy candidates becomes the one everybody knows.
That is worth remembering in a gallery. The room the Mona Lisa hangs in contains other Renaissance works of extraordinary quality that nobody photographs, because they were never stolen, never on a front page, never the subject of a two-year manhunt.
It is also worth remembering about the crowd. Eight million people a year stand in front of a small portrait, largely because a handyman in a white smock walked out with it on a quiet Monday and a very long time passed before anyone noticed.
The painting has been back on the wall for over a century now, behind glass, watched constantly. It is the most secure picture in the world, and its security is a direct legacy of the morning nobody was watching at all.
