In 1483, the painting The Virgin of the Rocks was comissioned by the San Francesco Grande in Milan by a roup of religious followers devted to the Immaculate Conception.  This group commissioned this painting to be on wooden panel so that it could eventually be placed inside of a larger piece of artwork on the altar of this church.  A few years after this painting was created, Leonardo created a second version which was restored around 2010 and is in the National Gallery in London whereas the original is unrestored in the Louvre.  The two paintings actually have several differences between the two of them inluding coloring differences, a halo over one of the Virgin Marys and not the other, and a couple of others.
