Patch of Grass, a painting composed by Vincent Van Gogh in 1887 in Paris hangs in the Kroller-Muller Museum in the Dutch city of Otherlo. With advanced X-ray technique called synchrotron radiation-based X-ray fluorescence mapping, a hidden colored face behind the painting is revealed as a detailed 3 dimensional image, giving historians, art connoisseurs and painting enthusiasts a way of understanding how the painter recycled his art. The technique is an invaluable tool to study hidden art in paintings.
About a third of Van Gogh’s paintings had been superimposed over previous compositions like the woman behind the Patch of Grass. If he had more canvasses to paint on, there might have been more of his paintings around to behold, study, and delight on. Credit: Reuters (07/30/08Van der Struik,T.)
