Behind the scenes: Leonardo’s Virgin of the Rocks
Fascinating online lecture from the National Gallery outlining the latest scientific research on Leonardo’s “Virgin of the Rocks”. The format of the event was an interview with Marta Melchiorre of the gallery’s scientific department by Carlo Corsato from the learning department, leading her though some of the newest scientific techniques to analyses painting in a non-invasive way and what they have shown us about this painting. I’m not sure I understood all the science but I was intrigued by the results. Most fascinating were new ways of mapping the chemicals in pigments across a painting and, in this case, a zinc map showed up the underdrawing more clearly as the drawing material contained the chemical.
