Infrared pho­tog­ra­phy has even revealed, says the nar­ra­tor of the new Inspi­rag­gio video above, that both paint­ings "share the same changes in the orig­i­nal sketch. For years, it has been known that Leonar­do made small cor­rec­tions to the shape of the Mona Lisa 's hands, adjust­ments to the line of the eyes, and sub­tle mod­i­fi­ca­tions to the curve of the face," the very same cor­rec­tions that were found in the new­ly exam­ined copy.
Apart from cer­tain stretch­es of absence, Leonar­do's Mona Lisa has been on dis­play at the Lou­vre for 228 years and count­ing. Though cre­at­ed by an Ital­ian in Italy, the paint­ing has long since been a part of French cul­ture. At some point, the rev­er­ence for La Joconde, as the Mona Lisa is local­ly known, reached such an inten­si­ty as to inspire the label Jocondisme. For Mar­cel Duchamp, it all seems to have been a bit much.
