What the Louvre Says
The Louvre’s official position is one of institutional honesty: the 2004 scientific examination conclusively proved the painting was never trimmed. Yet the museum also acknowledges that Renaissance copyists, particularly Raphael, were working from evidence of something different. The paradox isn’t a problem to be solved—it’s a genuine unresolved question.
2004—2005 Scientific Examination Statement
The Louvre commissioned an unprecedented technical examination of the Mona Lisa, coordinated by a consortium of international specialists. The findings were unambiguous:
Official Finding: “The painting has never been trimmed. The barbe (original gesso ridge) is intact on all four edges, proving this is Leonardo’s complete painted extent.”
- 39 international specialists participated
- Multiple analytical techniques applied: X-ray fluorescence (XRF), cross-section analysis, ultraviolet imaging, infrared reflectography
- Unanimous conclusion: no trimming occurred at any point in the painting’s documented history
- Results published in peer-reviewed scientific literature and museum conservation reports
2012 Curator Acknowledgment
During the restoration of the Prado copy in 2012, Vincent Delieuvin, the Louvre’s chief curator of paintings, made a statement that crystallized the institutional position:
“Raphael and other copyists must have based their copies on a version other than the one in the Louvre today.”
This statement is remarkable for what it represents: official acknowledgment of the column paradox. The Louvre’s most senior curatorial voice accepted that credible Renaissance evidence contradicts present reality. Significantly, Delieuvin did not claim that Raphael invented the columns or made an error. Instead, he acknowledged that something changed or that multiple versions existed.
This is institutional honesty about an unresolved question—a stance that respects both the scientific evidence and the historical record.
Current Display Information
Gallery Label (as of 2024)
The label provides standard attribution and dating (c. 1503—1519), along with technical notes on Leonardo’s sfumato technique. There is no mention of the column controversy or compositional variants. The emphasis remains on the painting as it appears today: complete, intact, and scientifically examined.
Educational Materials
Some Louvre publications do reference Raphael’s sketch and note compositional differences between his drawing and the Louvre painting. These materials generally avoid offering a definitive explanation, instead presenting the evidence as an interesting scholarly puzzle.
Conservation Position
The Louvre has no plans to remove the painting’s varnish to conduct further invasive analysis—the risk to the original surface is deemed too high. The painting remains stable under strict climate control and regular monitoring. Any future study would rely on non-invasive techniques developed since 2004—2005.
What This Means
The Louvre’s position can be summarized as follows:
- Incompleteness of answers: The institution doesn’t claim to have solved the mystery. The 2004 examination answered one question definitively (was the panel trimmed?), but left others open.
- Credibility of Renaissance evidence: The Louvre acknowledges Raphael’s sketch as genuine documentation of what a major artist saw in 1504. This evidence is not dismissed or explained away.
- Multiple possibilities remain open: The Louvre leaves room for the possibility of a separate version, a major compositional change by Leonardo himself, or evidence yet to be discovered.
- Scientific rigor as paradox creator: Ironically, it was the Louvre’s own commitment to rigorous conservation science that created the paradox in the first place. The 2004 examination proved too much: that the painting was untouched, yet Renaissance records suggest otherwise.
