Who is the mona lisa
Serga [27]
The Mona Lisa is one of the most famous artworks in the history of art. Leonardo da Vinci was the one who painted it. Some say it was a painting of Lisa Gherardini (just learned this in my Western Civ Class). The exact date in which Da Vinci started painting this picture is unknown however it is believed that he started painting the Mona Lisa around 1503 and completed around 1517. Hopefully this helps.
