Metal point heightened with white on paper, 1483
After hearing the recent news of a possible discovery of a Leonardo da Vinci drawing, I came across this beautiful study. This metal point drawing is a study for the painting Virgin of the Rocks. There are two versions of the painting, one is in the National Gallery, London, and the other at the Louvre in Paris. Below is a detail of the angel from the National Gallery.
