Copy of the "Mona Lisa", c1635-1660. Leonardo da Vinci (1452-1519) began a portrait of Lisa Gherardini about 1503 and then took with him to France, selling it to the French king in 1516. During the centuries that it remained in the royal collection it was copied many times. Some of the early copiests wanted to "complete" Leonardos composition by introducing columns at the sides of the composition, since in the original, now in the Louvre Museum in Paris, we can see indications of the base of columns along each side. However, extensive technical examinations of the Louvres panel and the paint along its edges have conclusively demonstrated that the painting was not cut down and therefore there were never columns along the side edges. So later copiests were trying to "improve" on what they saw!
