In the context of Virgin of the Rocks, explore the Dates of the Interpretation.
It is generally accepted by art historians that the Louvre version is the earlier work. Martin Davies, former director of the National Gallery, described the painting in the Louvre as being stylistically close to Leonardo's earlier works and the London painting more suggestive of his maturer style, and therefore the later of the two, and derivative of the Louvre painting. Most authors agree that the Louvre painting was the one that was painted to fulfil the commission of 1483.Some writers, including Martin Davies, feel that 1483 is too late a date for the Louvre version, and suggest that the painting had already been begun and perhaps completed in Florence before the commission. Wasserman, Ottino della Chiesa and others have pointed out that the measurements of both paintings are compatible with the altarpiece, and that it is an unlikely coincidence that Leonardo painted a picture that fitted the dimensions, at a time prior to the commission. Wasserman suggests that perhaps the Louvre painting was extended to fit the arched shape, and that the joint is no longer visible since the painting was transferred to canvas in the 19th century. Davies suggests that Leonardo painted the second version in the 1480s to fulfil the commission, and based it on the earlier work. Kenneth Clark agrees with this interpretation, placing the Louvre painting prior to 1481 and the London painting from 1483.The theory that is most commonly used to explain the existence of the two paintings is that Leonardo painted the Louvre Virgin of the Rocks to fulfil the commission, giving it a date of 1483, and that he then sold it to another client, and painted the London version as a replacement. In line with this theory, it is hypothesised that the Louvre painting was sold in the late 1480s, after some haggling over the final payment. The London painting was commenced in perhaps 1486 as a substitution for the "original" Louvre version, and was not ready for installation until 1508, after prolonged disagreement and negotiation. This explanation, which della Chiesa attributes to Venturi and Poggi, has gained wide acceptance, and is the version of events described on both the National Gallery and the Louvre websites. Martin Kemp dates the Louvre painting to 1483–1490 and the London painting to 1495–1508.Not all authors agree with either the dating or the theory that the Louvre painting was the earlier, was sold, and the London painting done as a substitute. Taylor asserts that the London painting is stylistically the earlier of the two, being more meticulous, in keeping with the product of Leonardo's Florentine training, while the Louvre painting has more in common with the Last Supper and the Virgin and Child with St Anne, including the delicate use of sfumato. Taylor argues that the London painting fulfils the requirements of the commission of 1483 in terms of iconography, and that the iconography of the Louvre painting indicates that it was painted for an entirely different clientele, and gives it a date in the 1490s.
