Composition The two paintings of the
Virgin of the Rocks that now belong to the National Gallery, London, and that belonging to the Louvre Museum, Paris, are the same in subject matter and in overall composition, indicating that one is derivative of the other. The two paintings differ in compositional details, in colour, in lighting and in the handling of the paint. Both paintings show a grouping of four figures, the Virgin Mary, the Christ child, the infant John the Baptist and an angel arranged into a triangular composition within the painting and set against a background of rocks, and a distant landscape of mountains and water. In both paintings, Mary makes the apex of the pyramidal figure group, stretching one hand to include John and raising the other above the head of the Christ child in a blessing. John kneels, gazing towards the Christ child with his hands together in an attitude of prayer. The Christ child sits towards the front of the painting, supported by the angel, and raising his right hand in a sign of
Benediction towards the kneeling John.
Differences Compositionally, all the figures are slightly larger in the London painting than in the Louvre painting. The main compositional difference between the two paintings is that while in the London painting the angel's right hand rests on his/her knee, in the Louvre painting the hand is raised, the index finger pointing at John. The eyes of the angel are turned down in a contemplative manner in the London painting, but in the Louvre picture are turned to gaze in the general direction of the viewer. In the London painting, all the forms are more defined, including the bodily forms of the clothed figures. The Louvre painting remains much as it was in 1939 when
Kenneth Clark lamented that "We can form no real conception of the colour, the values, or the general tone of the original, buried as it is under layer upon layer of thick yellow varnish. In the darks some mixture of bitumen has made the surface cake and crack like mud, and there are innumerable patches of old repaint all over the picture. All this must be borne in mind before we say that at this date Leonardo was a dark painter and an uninteresting colourist." Another difference is in the colouring of the robes, particularly those of the angel. The London painting contains no red, while in the Louvre painting, the angel is robed in bright red and green, with the robes arranged differently from those of the angel in London.
Angel musicians The two paintings of angels that are associated with the
Virgin of the Rocks and are in the National Gallery do not properly fulfil the original commission for two panels each showing four angels, singing on one side and playing musical instruments on the other. There are only two musicians, both turned the same direction and both playing musical instruments. One, in green, plays a vielle, and the other, in red, plays a lute. The positions of the feet and the drapery are similar, indicating that the same design has in part been utilised for both. The angel in red is thought to be the work of Ambrogio de Predis. The angel in green is the work of an unknown associate of Leonardo. The National Gallery suggests that it might be the work of Francesco Napoletano. In both cases the angel is standing in a grey painted niche. A reflectogram of the
Angel in green with a Vielle revealed part of a painted landscape. The background of the
Angel in red with a Lute could not be determined because the grey paint on that painting is thick and opaque. While it is commonly thought that the two angel panels were originally placed on either side of the central panel, an article published by the National Gallery suggests that they were placed higher up on the altarpiece. ==Interpretation==
