Attribution investigation · Leonard and his workshop
Is Salvator Mundi really by Leonardo da Vinci?
Contested award, restoration and record price.
Sold for $450.3 million in 2017 as a work by Leonardo, this blessing Christ remains one of the most controversial issues in art history. The material arguments are real, but they do not produce absolute consensus on the exact part of the master.
The short answer
A certain Leonardo? No. A simple fake? No more.
The most conservative wording is "Leonardo da Vinci and workshop", or "attributed to Leonardo da Vinci". The painting features compositional changes, modeling technique and design consistent with Leonardo. But its very damaged condition, the old restorations and the usual participation of the workshop prevent us from measuring with certainty what the master painted himself.
The National Gallery in London presented him as a Leonardo in its 2011-2012 exhibition. Christie's sold him under this name in 2017. Other specialists, however, believe that a large part of the execution goes to an assistant, often close to Giovanni Antonio Boltraffio.
The useful verdict
Design: most likely linked to Leonardo and his workshop.
Execution: discussed, possibly collective.
Material authenticity: old painting, not modern manufacturing.
Total attribution to Leonardo: supported by several experts, but not unanimously accepted.

What does Salvator Mundi represent?
Salvator Mundi means "Savior of the world". Christ looks head-on at the viewer, blesses with his right hand and holds the cosmos with his left hand. Leonardo - or his workshop - transforms an ancient iconographic formula into a silent and almost tactile presence.
The blessing
Two fingers raised and two folded make up a liturgical gesture. The thumb contour was changed during execution: this pentimento makes an important argument in favor of an original composition rather than a mechanical copy.
Crystal orb
The transparent sphere refers to the world and the cosmos. Luminous inclusions can evoke rock crystal, a material that Leonardo knew. Its optical rendering, long considered "incorrect", remains debated.
The face
The contours dissolve in the shadows while the hands are sharper. This pictorial depth of field, close to sfumato, supports attribution while being difficult to judge after losses and retouching.
A story with holes
From the Stuart court to rediscovery
The proposed provenance links the painting to English royal collections, but ancient identifications are never as simple as a modern inventory number. We must distinguish the documented presence of a Salvator Mundi from Leonard and the certainty that this is exactly the panel sold in 2017.
A royal work and an engraving
One Salvator Mundi attributed to Leonardo appears in the Stuart community. In 1650, Wenceslaus Hollar engraved the composition and recorded that it was painted by Leonardo, retaining an essential testimony to its appearance.
The Cook Collection
The panel enters the Cook collection with a secondary attribution, notably to Bernardino Luini. Its condition and repaintings then prevent recognition of a possible prototype.
A modest sale
Presented as Boltraffio's work, it is sold for 45 pounds. This figure is often opposed to the 2017 record, but above all it reflects the attribution and condition of the painting on that date.
Rediscovery in the United States
The sign reappears in a regional sale. Merchants bought it, then undertook a long restoration and a study campaign.
Exhibition in London
The National Gallery integrates it into Leonardo da Vinci: Painter at the Court of Milan. This public presentation gives decisive force to the new attribution.
The Christie's record
The painting sold in New York for $450,312,500 including fees, a world record for a work sold at auction.

Before and after restoration
The comparison explains much of the controversy. Before restoration, the face, hair and clothing were covered with repaint and varnish. After clearing, original areas reappear, but significant gaps must be reinstated to make the image readable.


Caution: restoring does not mean "inventing a new work", but any reintegration influences what the eye attributes to the painter. The current state should therefore never be read as an intact surface of 1500.
The heart of the debate
What arguments for and against Leonardo?
Which supports attribution
- The thumb pentimento indicates creative modification rather than servile repetition.
- The soft shape of the face, the curls and certain passages of the hand are reminiscent of sfumato and Leonardo's late procedures.
- The walnut panel, pigments and preparation are compatible with the practices of its environment.
- The composition corresponds to Hollar's engraving and is above many studio copies in its subtlety.
- The conception of the orb as a cosmic crystal is in line with Leonardo's research on optics and transparent materials.
Which maintains doubt
- The table is very damaged : part of what we see belongs to restorations.
- The blessing hand, the draperies and certain anatomy appear stiffer than in the undisputed works.
- Leonardo's workshop operated collectively; master design and assistant execution can coexist.
- More than twenty old versions make it difficult to identify the prototype and reconstruct its timeline.
- The proposed royal provenance involves interpreted stages, not a perfectly continuous documentary chain.
Three reasonable positions
Mainly Leonard
Position defended in particular by Martin Kemp and researchers who insist on the pentimenti, the modeling, the optics and the quality of certain passages.
Leonardo and workshop
Intermediate position today very useful: the project and some areas would be autographs, while assistants would have participated in the execution.
Mainly the workshop
Carmen Bambach proposed a strong participation from Boltraffio, with only certain interventions from Leonardo. Other catalogs also remain cautious.

The engraving of Hollar and the Ganay version
An attribution is not decided by isolating an image. Old copies and engraved covers make it possible to reconstruct the prototype, distinguish common inventions and measure the differences of each version.

Hollar, 1650
Engraving carries the memory of one Salvator Mundi associated with Leonardo. It confirms the frontal pose, blessing, loops and orb, but does not mechanically reproduce every detail of the current panel.

The Ganay version
This important workshop version shows a very similar composition, with differences in drapery, hand and orb. She recalls that the subject circulated within a workshop, in the form of a drawing, cardboard or shared model.
Art market
Why $450.3 million?
A prize for the work, but also for its story
Christie's included the painting in a post-war and contemporary art sale, introduced it as "the last Leonardo" still in private hands, and orchestrated a worldwide campaign. After nineteen minutes of auction, the price reached $450,312,500, including fees.
The amount brings together several rarities: the most famous name of the Renaissance, fewer than twenty generally recognized paintings, a spectacular rediscovery, a proposed royal provenance and competition between international buyers. However, the price does not constitute not scientific proof of attribution.
Where's the picture today?
An unofficially confirmed location
After the sale, a presentation at Louvre Abu Dhabi was announced and then postponed. The painting did not join the Léonard du Louvre exhibition in 2019. Since then, numerous articles have mentioned different places of conservation and owners acting through intermediaries, but no lasting public presentation has made it possible to verify these stories.
So the rigorous answer is simple: the work belongs to a private collection and its current material location is not publicly confirmed. Stories of a yacht, a Swiss safe or a future museum must remain presented as hypotheses, not as established facts.

Frequently asked questions
Salvator Mundi FAQ
Is Salvator Mundi authentic?
It's an ancient painting from the Leonardesque environment, not a modern forgery. The controversy concerns the exact part painted by Leonardo himself and that of his assistants.
Why do some experts attribute it to Boltraffio?
They bring together certain more rigid passages of Giovanni Antonio Boltraffio, an important student of Leonardo, while sometimes admitting interventions by the master in the hands, the orb or other areas.
What is the most convincing detail in Leonardo's favor?
The thumb pentimento shows a running search. The sfumato, loops, orb optics and some working prints are also often cited.
Did the painting really cost $450 million?
Yes. Christie's sold it for $450,312,500, including fees, on November 15, 2017 in New York.
Can you see Salvator Mundi in a museum?
No currently. It belongs to a private collection and is not permanently exhibited. The Ganay version and other old copies may occasionally be shown in exhibitions.
Why doesn't the orb distort the garment more?
One interpretation is that it is a symbolic rock crystal, not a literal optical demonstration. Simulations have also shown that certain sphere configurations can produce less distortion than one imagines.
