Vincent Van Gogh is thought to have regularly painted over his paintings. Using a new technique using "synchrotron radiation induced X-ray fluorescence spectroscopy", which is an improvement on X-ray radiography, a new portrait has been revealed. X-ray radiography has been used in the past to show painted over layers in famous paintings. The new technique was used to reveal the portrait of a yet unidentified female in Van Gogh's "Patch of Grass".
Pictures along with more detail are available at Fox News.
