A contemporaneous copy of the world’s most famous painting has been sensationally discovered by conservators at the Prado in Madrid, allowing us to see the Mona Lisa as she would probably have looked at the time.

In art historical terms, the discovery is nothing short of remarkable. The Prado painting had long been thought to be one of dozens of surviving replicas of Leonardo’s masterpiece, made in the 16th and 17th centuries.

But, the Arts Newspaper reports, recent conservation reveals that the work was in fact painted by a pupil working alongside Leonardo.

The original painting hangs behind glass and with enormous security at the Louvre, a gallery it is unlikely to ever leave. There is also no prospect of it being cleaned in the forseeable future, meaning crowds view a work that, although undeniably beautiful, has several layers of old, cracked varnish.

This newly discovered work – found under black overpaint – allows the viewer to see a much fresher version of the captivating young woman, generally acknowledged to be Lisa Gherardini, the wife of the Florentine cloth merchant Francesco del Giocondo.

The Prado said the restoration had been carried out over the past few months in preparation for an exhibition at the Louvre in March.
