A new analysis of a charcoal drawing that has puzzled experts for centuries suggests that it was likely created by Leonardo da Vinci.
The “Mona Vanna,” better known as the "Nude Mona Lisa," was long thought to be from da Vinci’s studio, AFP reports. However, analysis of the drawing at the C2RMF laboratory beneath the famous Louvre Museum in Paris indicates that the famous artist himself may have created the work.
The figure’s hands and body bear similarities to the "Mona Lisa," and may have been used in da Vinci’s preparations for the masterpiece. Citing microscopic exams of the work, AFP reports that the “Mona Vanna” was drawn from top left to bottom right, which indicates that it is the work of a left-handed artist such as da Vinci.
Purchased by the Duc d’Aumale in 1862, the drawing is in the collection of the Condé Museum at the Chateau de Chantilly, north of Paris.
“The Italian master spent a lot of time perfecting his work,” explained the Domaine de Chantilly, in a statement emailed to Fox News. Laboratory analysis shows that the Chantilly drawing "was used as a tracing (to transfer the composition) for paintings probably created in his workshop,” it added.
The “Mona Vanna,” sketch is almost as large as the “Mona Lisa” itself. The famous painting is housed in the Louvre.
2019 marks the 500th anniversary of da Vinci’s death and the “Nude Mona Lisa” will feature prominently in a Condé Museum exhibition this summer. “In the manner of a police investigation, and in an immersive way, the visitor will discover the results of the scientific analyses,” explained the Domaine de Chantilly, in its statement.
Da Vinci continues to be a source of fascination. Later this year, The British Library in London is set to showcase a number of Leonardo da Vinci's most important notebooks, all written in his famous “mirror-writing.”
The "Leonardo da Vinci: A Mind in Motion" exhibit will include notes and drawings from three of his most revered scientific and artistic notebooks, the "Codex Arundel," the "Codex Forster" and the "Codex Leicester."
In addition to using his own shorthand, da Vinci also wrote his personal notes starting on the right-hand side of the page. It is not clear whether this so-called mirror writing was a way to keep his notes private or simply a means to prevent smudging, as da Vinci was left-handed.
Last year, experts in Italy said they had found the earliest surviving work by da Vinci. The small glazed terracotta tile, described as a self-portrait of the artist as the Archangel Gabriel, was unveiled at a press conference in Rome.
However, the tile’s authenticity was questioned by noted Leonardo expert Martin Kemp, professor emeritus of the history of art at the University of Oxford.
The painting grabbed headlines around the world when it was sold at Christie’s auction house in New York. "Salvator Mundi," Latin for "Savior of the World,” is one of fewer than 20 paintings by da Vinci known to exist and the only one in private hands.
