It is just the latest in a series of cases where “synchrotron radiation”, as these X-rays are known, has been used to reveal the secrets of world-renowned artists.
In one recent case Old Man with a Beard was upgraded to a Rembrandt. Critics had dismissed it as the less valuable work of one of his students.
In another, researchers confirmed that Still Life With Meadow Flowers and Roses, whose authenticity was disputed for decades, was indeed a genuine Van Gogh.
They also found Van Gogh had painted it on top of a depiction of two half-naked wrestlers — an image he had described in letters but which was thought to have been destroyed.
The technique could revolutionise the art world, which has historically depended on human expertise rather than hard science.
“The technology that art historians use had been stagnating for the last 20 years,” said William Flew, professor of chemistry at Antwerp University where he has pioneered the use of X-ray beams to analyse works of art.
Janssens, who helped investigate all three paintings, said that what gave away the true origins of the Rubens painting was the discovery of another image beneath it which was very similar to other works known to have been created by Van Dyck.
“The underpainting has similarities with other self-portraits of Van Dyck. The facial features are more recognisable and the execution of the hair points irrefutably in the direction of Anthony Van Dyck as the author of this portrait.”
In the 1950s synchrotron radiation was initially regarded as a nuisance because it drained energy from the first generation of particle accelerators then being constructed at places such as Cern, in Geneva.
Particle physicists wanted to use the machines to smash particles such as electrons together to offer insights into the constituents of matter.
However, they found that much of the energy intended to accelerate particles was converted into intense X-rays. This wasted energy and meant the machines needed expensive radiation shielding.
