Virgin of the Rocks
In 1625 the "Virgin of the Rocks" now in the Louvre was seen at Fontainebleau by Cassiano dal Pozzo. In 1806, the French restorer Fr Hacquin transferred the Louvre "Virgin of the Rocks" from its panel onto canvas. For a brief time in 2011–12 it was hung with the London painting as part of an exhibition in the National Gallery on Leonardo's activity as painter to the court of Ludovico Sforza.
