A charcoal attracting housed another workmanship gathering for over 150 years may have been an outline for the Mona Lisa, a French craftsmanship master says.

The charcoal representation of a naked lady, known as the Monna Vanna, was already credited just to Leonardo da Vinci’s studio.

However, specialists have sufficiently discovered signs to recommend the craftsman dealt with both.

After tests at the Louver Museum in Paris, keepers trust the outline is “at any rate to a limited extent” by Leonardo.

It has been held since 1862 in the gathering of Renaissance workmanship at the Conde Museum at the Palace of Chantilly, north of the French capital.

Leonardo da Vinci (1452-1519) was one of the considerable painters of the Italian Renaissance, and his Mona Lisa oil painting (otherwise called La Gioconda) stays one of the world’s most conspicuous and important masterpieces.

It is accepted to have been a commission from fabric dealer and Florentine authority Francesco del Giocondo for a picture of his better half, Lisa Gherardini.

In any case, Mr Mottin brought up that incubating on the highest point of the gravitating toward the head had been finished by a right-gave individual while Leonardo drew with his left hand.

“We should stay reasonable,” he told AFP, as work proceeded.

“It is work that will take some time,” he said. “It is an extremely troublesome attracting to take a shot at on the grounds that it is especially delicate.”
