The Mona Lisa originally had eyebrows, according to a French art expert who has analysed Leonardo da Vinci's masterpiece with a special camera.
法国一位艺术专家日前称，蒙娜丽莎原本有眉毛。这位专家在使用一种专业相机对莱昂纳多?达芬奇的名作（《蒙娜丽莎的微笑》）进行分析后得出了该结论。
Pascal Cotte said da Vinci built the painting up in layers, the last being a special glaze whose optical properties increased the illusion of a three-dimensional face. Above the glaze Da Vinci painted details such as the eyebrows.
帕斯卡尔?柯特称，达芬奇在绘制这张画时使用了多层颜料，最表面的一层使用了一种特殊釉料，这种颜料的光学性能可增加人物面部的三维效果。在这层釉料上面，达芬奇绘制了眉毛等细节部位。
Cotte said: "That could explain why the eyebrows have disappeared – they have faded because of chemical reactions or they have been cleaned off."
柯特说：“这可以解释为什么眉毛不见了，可能是由于化学反应褪色了，或是被擦掉了。”
