MSN 台灣 新聞 - 科學家新技術 梵谷隱藏畫現身
更新日期:2008/07/31 10:45
（路透阿姆斯特丹30日電）荷蘭德爾夫科技大學（Delft University of Technology）今天表示，科學家採用先進的X光線技術，讓原先隱藏於梵谷（Vincent van Gogh）畫作「一塊綠草地」（Patch of Grass）中的一幅畫像現形。
這幅非常精細的畫像現出一名女性的臉，可讓藝術史家更了解梵谷成為畫家的過程。
德爾夫科技大學科學家狄克（Joris Dik）說：「我們估計，梵谷早期的畫作有三分之一是畫在既有作品上。梵谷的確會再利用自己的油畫作品」。
德爾夫科技大學表示，一般X光線技術只會照出藏身畫無色、局部概觀，僅能看出「一塊綠草地」下一個人的模糊輪廓。
狄克表示：「我們對該畫作採用虛擬立體模型，層層抽絲剝繭，就得出非常精細的隱藏面容」。中央社（翻譯）

AMSTERDAM (Reuters) - Scientists have made a colored view of an early rejected painting underneath Vincent van Gogh's 'Patch of Grass' painting, using advanced X-ray techniques, a Dutch university said on Wednesday.
The very detailed image shows the face of a woman and may give art historians a better understanding of the way Van Gogh developed as a painter.
"It is estimated that one third of Vincent van Gogh's early paintings have been painted on top of existing ones. Van Gogh literally recycled his own canvasses," scientist Joris Dik of the Delft University of Technology said.
Conventional X-ray techniques give a colorless, partial view of the hidden painting and only show vague contours of a person behind 'Patch of Grass', the university said.
By recycling his work Van Gogh painted many layers over the original painting but the scientists managed to scan all the different elements in those layers of the relevant area with X-ray fluorescence.
"We can make a virtual 3-dimensional model of the painting and start to peel off all the layers one by one. Then we get a nice detailed view of the hidden face," Dik said.
Van Gogh painted 'Patch of grass' in 1887 in Paris and it hangs in the Kroller-Muller museum in the Dutch eastern city of Otterlo.
