On August 11, 1911, the Mona Lisa, Leonardo da Vinci's masterpiece, was stolen from the Louvre Museum in Paris. The thief, Vincenzo Peruggia, a Louvre employee, stored the painting in the false bottom of a trunk in his flat for two years and then tried to sell it to his native Italy for $95,000. Italian officials promptly arrested him and returned the 300 -year old masterpiece to France without a scratch. At his trial in Florence, Peruggia convinced the jury that his act was one of patriotism-that his sole motive was to return the famous painting to the land of its creator. Because of this declaration, he received a relatively light sentence of 1 year and 15 days.
