This version of the Mona Lisa (Louvre) was painted by one of Leonardo’s pupils, probably Salaí (1480-1524) or Francesco Melzi (1493-1572/3). The fact that each pentimento, or change, in Leonardo’s original (to the bust, outline of the veil and position of the fingers) is repeated here suggests that the two works were created simultaneously. There are also differences with respect to the original, in the unfinished landscape and on the face. Overall, the panel seems to reflect an intermediate stage in the creation of the Louvre painting.
