In 1911, Leonardo Da Vinci's "Mona Lisa" was stolen from the Louvre by an Italian who had been a handyman for the museum. The famous painting was recovered two years later.
A statue called "Young Girl with Serpent" by Auguste Rodin was stolen from a home in Beverly Hills, California, in 1991. It was returned after someone offered it on consignment to Christie's auction house. Rodin, a French sculptor considered by some aficionados to have been the father of modern sculpture, lived from 1840 until 1917. His most famous work, "The Thinker," shows a seated man with his chin on his hand.
