She is widely seen as proof that good looks can lastforever.But,at over 500 years of age, time is catching up with the Mona Lisa.
The health of the famous picture, painted by LeonardoDa Vinci(莱昂纳多·达·芬奇)in 1505, is getting worse bythe year, according to the Louvre Museum(卢浮宫博物馆)where it is housed."The thin,woodenpanel on which the Mona Lisa is paintedin oil has changed shape since expertschecked it two years ago."the museumsaid.Visitors have noticed the changesbut repairing the world's most famous painting is not easy.Experts are not sure about the materials the Italian artist used and their currentc现在的)chemicalstate.
Nearly 6 million people go to see the Mona Lisa everyyear,and many are attracted by the mystery of her smile."It is very interesting that when you're not looking at her,sheseems to be smiling,and then you look at her and shestops."said Professor Margaret Livingstone of HarvardUniversity."It's because direct visionc视觉)is excellent atpicking up details,but tess suited to look at shadows.DaVinci painted the smile in shadows."
However,the actual history of the Mona Lisa is just asmysterious as the smile.Da Vinci himself loved it so muchthat he always carried it with him,until it was eventuallysold to France's King Francis I in 1519.
In 1911,the painting was stolen from the Louvre by aformer employee,who took it out of the museum hiddenunder his coat.He said he planned to return it to Italy.The painting was sent back to France two years later.
During World Warll,French hid the painting in smalltowns to keep it out of the hands of German forces.
