Mona Lisa’s Missing Necklace

蒙娜·丽莎失去的项链

蒙娜·丽莎是意大利著名画家达·芬奇的代表作，几百年来人们对蒙娜·丽莎那迷人的微笑争论不休。而美国人利用现代技术对该画进行扫描得出的结果更令人困惑，为这一名画增添了又一种神秘色彩。你知道这是什么吗?

A camera and a computer can “see” something that perhaps millions of pairs of eyes failed to see for 480 years：the Mona Lisa's lost necklace．The discovery about the famous painting was made by an American physicist in 1986．

    The Mona Lisa，painted by the Italian，Leonardo da Vinci，has been on show for many years in Paris．Now，a row of white spots on the neck have been “seen”．They are said to be the remains of a necklace which the artist later painted over．

    The painting will be examined further by using infrared scanning techniques．Laser technology can be used to show what lies directly under the surface of the finished work，too．This will help us to understand how the artist drew the picture．Did he begin with a quick-made drawing or have second thoughts as he painted the picture?

    This kind of knowledge will show us the famous artist at work．It may also help to explain Mona Lisa's smile，which has puzzled art lovers for centuries．
