London's National Gallery of Art boasts a world-class collection of art. In addition to paintings by iconic Impressionist artists and legendary English landscape painters, the museum houses many works by Renaissance masters, like Leonardo da Vinci's Virgin of the Rocks. Since acquiring the panel painting in 1880, the museum has considered it a highlight of its collection. In recent years, however, this priceless painting has become even more precious, as the gallery has discovered there's much more than meets the eye.
During an 18-month restoration of the painting in 2008, conservators at the National Gallery of Art uncovered a pair of drawings hidden beneath the visible layers of oil paint. More recently, however, they've been able to see them in much greater detail. Rendered in a a zinc-based pigment, the sketches were detected by cutting-edge tools and techniques employed by the museum. These include macro X-ray fluorescence, which non-invasively maps out the surface of a painting, and hyperspectral imaging, which shows the spectrum present in an image's pixels. Together, these technologies proved that Leonardo's vision for Virgin of the Rocks drastically evolved during the painting process.
While one drawing simply shows a shift in the positioning of baby Jesus' head, another reveals that, at one point, Leonardo considered an entirely different composition. Rather than feature Jesus to the right of his mother, the earlier draft shows the infant in the arms of the angel on her left. Though Mary looks at her child in both cases, her gaze is different in each one. In the first version, she appears to be in awe of the young holy figure; however, in the finished painting, she looks on with a more maternal expression.
In addition to these underdrawings, restoration efforts also revealed another hidden gem: a handprint. Both of these discoveries are currently in the spotlight thanks to Leonardo: Experience a Masterpiece, an upcoming exhibition at the National Gallery. Opening on November 9, 2019, this spectacle will transform the ground floor of the gallery into four immersive spaces: the mind of Leonardo, a painting studio, a “light and shadow experiment,” and a chapel. By exploring these engaging spaces, visitors will be able to get up-close and personal with the painting in order to see it in a new light.
“This exhibition represents a fascinating new venture for the National Gallery, combining the most recent technical research on the Virgin of the Rocks with an immersive, enveloping experience,” Dr.Gabriele Finaldi (the director of the National Gallery) says, “giving visitors the opportunity to explore Leonardo da Vinci's creative process in making this masterpiece.”
Leonardo: Experience a Masterpiece will be on view from November 9, 2019 through January 12, 2020.
