An unexpected encounter

“Salvator Mundi” (Savior of the World) a painting of Jesus Christ that, after centuries of neglect, has been identified as Leonardo da Vinci’s by New York art dealer and da Vinci expert Robert Simon.

Initially, Modestini and Simon thought it was a work attributed to Leonardo workshop. Only through restoration could it be identified as an original work of Leonardo da Vinci.

Up until now nobody knew of the existence of this 66 x 45 centimenter walnut panel oil painting whose distinguished features were laying dormant over layers of crude oil paint.

The King of England Charles I (1600-1649) owned the painting before it moved from one owner to another in private possessions until 2005, when its last owner brought this painting to Simon for studying it. The fact that it existed was known to Da Vinci’s followers, but experts believed that it had been destroyed.

When it finally landed on Modestini’s hands, she wasn’t even aware that the painting which she was holding, is the first painting of Da Vinci to have been discovered in a 100 years. The cost of the painting today is around $200 million as per some estimates.

Without knowing the truth of the painting, Miss Modestini kept removing the layers of the varnish painstakingly in her studio. As she did so, Simon studied the provenance of the painting carefully, while comparing it with other paintings of Da Vinci, and the truth revealed itself.

Two important clues helped light the way.

Firstly it was the so-called “pentimento” – it is an alteration of any painting which reveals traces of the previous work. Simon used a photo of the painting using night vision and examining it painstakingly led to the final discovery.

The other was the painting of Christ’s curls.

“I was looking at the curls and St. John the Baptist at the Louvre, who has this huge head of massive ringlets and they are exactly the same,” said Modestini.

Infrared reflectograms were used to check below the layers, and that’s when the thumb in the blessing hand was discovered. Also, the stole Christ is wearing is painted in different positions.

The various elements in the painting, and especially their positions, looked similar to Da Vinci’s way of depicting art.

The restoration process applied


Salvator-Mundi-Leonardo-how they knew it was genuine

Modestini began cleaning the foggy varnish and the over-paint making use of solvents. On doing so, the painting’s true identity revealed itself. It took just a couple of hours in the first session, for Modestini to be able to see the work more clearly.

The next step was to take the cracked painting away and piece it back together again, a procedure that took about an year.

“It is quite a delicate process,” said Modestini. “It has to be very precise.”

Later in order to refine the lips and the eyes of Christ, she had to re touch the badly damaged areas.

The process was not only lengthy but also particularly difficult because, she said, she had “to make the decision of what to touch and what to leave alone.”

“I wanted (to be sure) that none of my restorations had impinged on the original, that I had not done too much, because old pictures have to look old — if you take out every crack, every spot, every anomaly, they can easily look like a reproduction,” she revelead.
