“The Mona Lisa is one of the most enigmatic and iconic pieces of Western art. It has inspired countless copies, but one replica at the Madrid’s Museo del Prado is generating its own buzz: Conservators say that it was painted at the same time as the original — and possibly by one of the master’s pupils, perhaps even a lover.

Juxtaposing the two paintings — and using infrared technology, which works like an X-ray, allowing one to see beneath the paint to see previous, obscured versions — conservators say that Leonardo and the painter of the replica made exactly the same changes at the same time.”

Whoa.  Link
