“Girl Reading a Letter at an Open Window” is one of the better-known paintings by one of the greatest Dutch artists, Johannes Vermeer.
Since it was created in the 17th century, the painting went through a years-long restoration undertaken by the Gemäldegalerie Alte Meister in Dresden.
When the restoration was completed, the discovery made through the restoration process gave a completely new outlook on the painting.
As colossal.com points out, what was once thought to be a somewhat glum depiction of a young girl reading near a window is now an amorous portrayal thanks to the unveiling of a naked Cupid hanging in the background.
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.
The new restoration—dive into the lengthy process in the video below—is just one of the mysteries that’s surrounded “Girl Reading a Letter at an Open Window” since its creation between 1657–59. Originally attributed to Rembrandt and later to Pieter de Hooch, the artwork wasn’t properly credited until 1880. The piece is evocative of another one of Vermeer’s works, “Lady Standing at a Virginal,” though, which similarly features a painting within a painting by showing a solitary figure standing near a window with Cupid on the wall behind her.
