Madonna of the Rocks
Here you see two versions of the famous painting Virgin of the Rocks by Leonardo da Vinci.

Leonardo da Vinci was commissioned in April 1483 by the Confraternity of the Immaculate Conception in Milan to paint the central panel of a triptych (three-part altarpiece) that was to be displayed in the religious order's oratory in the church of San Francesco Grande. The side panels depicting singing and music-making angels were to be executed by brother artists Ambrogio and Evangelista de Predis .

Between 1483 and 1508, Leonardo had painted two variant versions of the same composition. His Madonna of the Rocks (1482-1486) presently resides in the Louvre in Paris, while the Virgin of the Rocks (ca. 1491-1508), the former painting's replacement, hangs in the National Gallery, London.

It's not known why Leonardo has made two versions of the painting. Most people assume that the confraternity brothers were not happy with the first version, but there is no (written) proof for that.
