The Virgin of the Rocks (), sometimes the Madonna of the Rocks, is the name of two paintings by the Italian Renaissance artist Leonardo da Vinci, of the same subject, with a composition which is identical except for several significant details. The version generally considered the prime version, the earlier of the two, is unrestored and hangs in the Louvre in Paris. The other, which was restored between 2008 and 2010, hangs in the National Gallery, London. The works are often known as the Louvre Virgin of the Rocks and London Virgin of the Rocks respectively. The paintings are both nearly 2 metres (over 6 feet) high and are painted in oils. Both were originally painted on wooden panels, but the Louvre version has been transferred to canvas. Both paintings show the Mary and child Jesus with the infant John the Baptist and an angel Uriel, in a rocky setting which gives the paintings their usual name. The significant compositional differences are in the gaze and right hand of the angel. There are many minor ways in which the works differ, including the colours, the lighting, the flora, and the way in which sfumato has been used. Although the date of an associated commission is documented, the complete histories of the two paintings are unknown, leading to speculation about which of the two is earlier. Two further paintings are associated with the commission: side panels each containing an angel playing a musical instrument and completed by associates of Leonardo. These are both in the National Gallery, London. The paintings Louvre version The Virgin of the Rocks in the Louvre is considered by most art historians to be the earlier of the two and dates from around 1483–1486. Most authorities agree that the work is entirely by Leonardo. It is about 8 cm (3 in) taller than the London version. The first certain record of this picture dates from 1625, when it was in the French royal collection. It is generally accepted that this painting was produced to fulfill a commission of 1483 in Milan. It is hypothesised that this painting was privately sold by Leonardo and that the London version was painted at a later date to fill the commission. There are a number of other theories to explain the existence of two paintings. This painting is regarded as a perfect example of Leonardo's "sfumato" technique. London version A very
