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
Leonardo da Vinci (April 15, 1452 – May 2, 1519) was an Italian Renaissance painter and polymath who achieved legendary fame and iconic status within his own lifetime. His renown primarily rests upon his brilliant achievements as a painter, the "Mona Lisa" and the "Last Supper", being two of the most famous artworks ever created, but also upon his diverse skills as a scientist and inventor. He became so highly valued during his lifetime that the King of France bore him home like a trophy of war, supported him in his old age and, according to legend, cradled his head as he died.
