Theft of the Mona Lisa

On this day in 1911 curators at the Louvre discovered that the Mona Lisa had been stolen. Among the suspects were the 32 year-old poet Guillaume Apollinaire and a 29 year-old semi-famous painter named Pablo Picasso. The tale appears on page 109 in A Book of Ages. Picasso appears ten times in the book, Apollinaire once. The painting appears twice, being stolen and being painted by da Vinci when he was 51.
