Infrared light reveals hidden portrait beneath 1943 René Magritte painting

Researchers at the Royal Museums of Fine Arts of Belgium, using infrared reflectography, have discovered an earlier painted portrait of a woman underneath René Magritte's 1943 painting, La Cinquième Saison, from 1943—possibly a portrait of his wife, Georgette. The work is part of an ongoing research project to scientifically explore the artist's painting materials and techniques. The discovery will be one of many findings included in a new book, René Magritte: The Artist’s Materials, to be published later this month by the Getty Conservation Institute in Los Angeles.

“Although there have been plenty of times when the technical examination of artworks has revealed a second image beneath a painting’s surface, it is always exciting when a new example is discovered," Thomas Learner, head of science at the Getty Conservation Institute, told The Guardian. "In this case, the IR reflectography image is so clear and striking that it even raises the possibility of identifying the sitter."

As previously reported, X-rays are now a well-established tool to help analyze and restore valuable paintings because the rays' higher frequency means they pass right through paintings without harming them. X-ray imaging can reveal anything that has been painted over a canvas or where the artist may have altered his (or her) original vision. For instance, Vermeer's Girl Reading a Letter at an Open Window was first subjected to X-ray analysis in 1979 and revealed the image of a Cupid lurking under the overpainting. And last year, conservationists who were conducting an X-ray analysis of Vincent van Gogh's Head of a Peasant Woman discovered a hidden self-portrait on the back of the canvas. In 2008, European scientists used synchrotron radiation to reconstruct the hidden portrait of a peasant woman painted by Van Gogh.
