Hi-tech imaging reveals the artist tinkered with Herri met de Bles’s painting to improve the composition of figures

One benefit of being among history’s greatest artists is that if you don’t much like a painting done by someone else, you can just improve it. The Flemish master Sir Peter Paul Rubens certainly knew how to paint people; Rubenesque is still used to describe a curvaceous, ample body. So when he noticed the inferior quality of the religious figures depicted on an otherwise accomplished landscape hanging on his wall, it turns out he simply picked up his paint palette.

A newly rediscovered Herri met de Bles painting, titled The Holy Family with the Infant Saint John the Baptist in an Extensive Landscape with Travellers, set a puzzle for art historians because the style of the landscape background did not match the group of people. Hi-tech imaging of the canvas carried out by a London auction house has since “completed the jigsaw”, revealing the way Rubens had tinkered with a painting now thought to have belonged to his own collection.
