A years-long restoration undertaken by the
Conservators knew the image of the Roman god of love existed after a 1979 X-ray, although it was assumed that Vermeer had altered the piece himself. Only after they performed a series of infrared reflectography imagings, microscopic analyses, and X-ray fluorescence examinations in 2017 did they realize that the Cupid was covered decades after the painter’s death, even though they still aren’t sure who marred the original piece or when. This dramatic of an alteration is rare during restoration, considering standard processes generally involve simple cleaning and repairs.
“When layers of varnish from the 19th century began to be removed from the painting, the conservators discovered that the ‘solubility properties’ of the paint in the central section of the wall were different to those elsewhere in the painting,”
