Mona Lisa by Leonardo da Vinci
The most famous painting in the world was painted by Leonardo da Vinci between 1503 and 1506. The title Mona Lisa did not come from the painter himself, but from the Renaissance art historian Giorgio Vasari. The painting is believed to be the portrait of Lisa del Giocondo, wife of wealthy Florentine silk merchant Francesco del Giocondo. It has been on permanent display in the Louvre Museum in Paris since 1797.
