How Art Restoration Revealed a 500-Year-Old Secret

[00:00:00]In 2011, a major restoration began at the Prado Museum in Madrid on a canvas that for centuries had been considered just one of many unremarkable copies of the famous Mona Lisa. The background of the painting was almost entirely black and the work itself seemed significantly less expressive than the Louvre masterpiece. But during the restoration, something unexpected happened. Beneath the gloomy black layer lay a genuine pristine landscape replicating the background of Leonardo da Vinci's original canvas in the finest detail.

[00:00:33]Further research revealed an even more stunning truth to the world. By examining the underdrawings and corrections hidden beneath the paint, scientists realized this painting was not a copy. An unknown artist created his work simultaneously with Leonardo.

[00:00:49]He sat in the same studio shoulder to shoulder with the great genius, step by step repeating every stroke of the master's brush.

[00:00:57]But who painted this mysterious Mona Lisa? And why did someone years later decide to ruthlessly paint over the beautiful Italian landscape? Let's find out in this video.

[00:01:08]For a long time, the fate of this painting was quite modest. It had been in the collection of the Prado Museum since the early 19th century and attracted almost no attention from the general public. Art historians considered it a late copy of the Louvre Mona Lisa and since dozens of such copies existed, the work was not considered particularly valuable. The painting looked significantly worse than the original. The model's face seemed less lifelike. The colors were duller and instead of the famous fantastical landscape, viewers saw a solid black background. Many experts believed that the unknown artist simply decided to simplify Leonardo's composition or was unable to reproduce the master's complex landscape. Everything changed when the Prado Museum began preparing for a major exhibition dedicated to Leonardo da Vinci and his workshop, deciding to carefully remove the black background before the exposition. Restorers cautiously began the removal process, and as the surface was cleaned, the painting seemed to come alive. Cliffs, winding paths, and bridges gradually appeared. The result was sensational. It became clear that the painting originally contained a complete landscape, identical to the one we see in the Louvre Mona Lisa. During technical analysis, experts compared the underdrawings and corrections on both paintings. It is a known fact that Leonardo constantly changed details of his compositions during the working process, adjusting the position of the hands, altering the contours of the clothing, and refining the model's facial features. Surprisingly, the exact same changes were found on the Prado version. If the artist had simply copied the finished painting, he would not have been able to reproduce all the intermediate stages of the master's work. Studies showed that both paintings developed in parallel. When Leonardo made changes to the original, the author of the Prado version almost simultaneously repeated these corrections on his own canvas, making this fact one of the most important arguments in favor of a groundbreaking hypothesis.

[00:03:12]The Prado Mona Lisa was created directly in Leonardo's workshop at the exact time the original was being painted, serving essentially as a twin rather than an ordinary copy.

[00:03:23]The Prado Mona Lisa holds a major advantage over the original. Even though both paintings are over 500 years old, the Prado version has been preserved significantly better, allowing us to imagine what Leonardo da Vinci's work might have looked like in the early 16th century. Many people are accustomed to seeing the Mona Lisa as a painting with characteristic yellowish green hues. But did you know that it only acquired this look centuries later? The Louvre original has been subjected to the effects of time, numerous restorations, and the natural aging of its paint layers. Over five centuries, the protective varnish covering the painting has gradually darkened, taking on an amber-yellow tint. As a result, not only have the colors changed, but the overall perception of the masterpiece has shifted. The paints have become less vibrant, and certain subtle nuances of chiaroscuro and fine details have been obscured beneath a layer of dulled coating. Therefore, the Mona Lisa that viewers see today is not entirely the same painting that once left Leonardo's studio. The Prado version was painted on a high-quality walnut panel and has retained much brighter and more vibrant colors. Thanks to the removal of the black background during restoration, numerous details have been revealed that are much harder to distinguish on the original today. Here, the transparent veil on the model's hair is clearly visible, and elements of her clothing are easier to discern, such as the embroidery along the neckline, the translucent cape on her left shoulder, the details of the armrest, and the subtle features of the background landscape.

[00:05:00]Because of this, the Prado version has become a unique window into the past, allowing us to see the richness of color, the depth of perspective, and the intricate details that Da Vinci's Mona Lisa once possessed. Through this painting, the modern viewer can better imagine what Leonardo's masterpiece looked like before five centuries altered its appearance. This is precisely what makes it so uniquely valuable.

[00:05:26]However, the main question remains unanswered. Who could be the author of this work? Since Leonardo directed a large and active workshop, numerous students worked around him throughout his career. Some of them were exceptionally talented artists who participated in the creation of works associated with their master.

[00:05:45]Researchers most frequently named two candidates. The first is Francesco Melzi, Leonardo's most devoted and educated pupil. After Leonardo's death, Melzi inherited a substantial portion of his teacher's manuscripts and drawings.

[00:06:00]He was a highly skilled artist and understood Leonardo's methods better than almost anyone else. The second candidate is Gian Giacomo Caprotti, better known by the nickname Salai. He spent more than 20 years at Leonardo's side as an assistant, student, and close companion. Salai was intimately familiar with the master's habits, posed for several of his works, and played an active role in the daily life of the workshop. None of the theories have received definitive confirmation, but we know this artist worked next to Leonardo and saw the birth of the masterpiece with his own eyes. One final question remains. Who would need a black background that hid an entire landscape?

[00:06:42]It is only known that the black overpaint was applied in the early 18th century, but this intervention unexpectedly played a positive role by reliably isolating the original background from light, dust, and subsequent restorations. Ironically, the attempt to alter the painting ultimately helped preserve its pristine appearance for future generations.

[00:07:04]Today, the Prado Mona Lisa is considered one of the most valuable works associated with the great artist's workshop. It allows us to view the process of creating the legendary portrait literally from the inside.

[00:07:16]Paradoxically, it is the painting that was considered an insignificant copy for many years that helped uncover numerous secrets of the original. Sometimes the most important discoveries are hidden not in famous masterpieces, but in works that almost no one paid attention to for centuries. The story of the Prado Mona Lisa reminds us that art continues to keep its secrets even after 500 years.

[00:07:41]Modern technologies allow researchers to find answers to questions that until recently seemed unsolvable. And although we still do not know for sure who exactly painted this mysterious picture, Salai, Melzi, or another of Leonardo's apprentices, one thing is certain.

[00:07:59]Before us is not just a copy. It is a unique witness to the birth of the most famous portrait in human history.
