Isleworth Mona Lisa
According to Leonardo's early biographer Giorgio Vasari, Leonardo had started to paint "Mona Lisa" in 1503, but "left it unfinished". However, a fully finished painting of a "certain Florentine lady" surfaced again in 1517, shortly before Leonardo's death and in his private possession. The latter painting almost certainly is the one that now hangs in the Louvre. Based on this contradiction, supporters of the authenticity of the "Isleworth Mona Lisa" claim it is the unfinished "Mona Lisa", made at least partially by Leonardo, and the Louvre "Mona Lisa" a later version of it, made by Leonardo for his own use.
Cultural references to Leonardo da Vinci
No painting has been more imitated and satirised than the "Mona Lisa". Beginning possibly with a naked portrait of Diane de Poitiers by Clouet, the pose and expression have been freely adapted to many female portraits.
The avant-garde art world has made note of the undeniable fact of the "Mona Lisa's" popularity. Because of the painting's overwhelming stature, Dadaists and Surrealists often produce modifications and caricatures. Already in 1883, "Le rire," an image of a Mona Lisa smoking a pipe, by Sapeck (Eugène Bataille), was shown at the "Incoherents" show in Paris. In 1919, Marcel Duchamp, one of the most influential modern artists, created "L.H.O.O.Q.", a "Mona Lisa" parody made by adorning a cheap reproduction with a moustache and a goatee, as well as adding the rude inscription, when read out loud in French sounds like "Elle a chaud au cul" literally translated: "she has a hot ass". This is a manner of implying the woman in the painting is in a state of sexual excitement and availability. This was intended as a Freudian joke, referring to Leonardo's alleged homosexuality. According to Rhonda R. Shearer, the apparent reproduction is in fact a copy partly modelled on Duchamp's own face.
