Picasso painted La Misereuse Accroupie in 1902, and it is currently on display at the Art Gallery of Ontario. The researchers used a non-invasive technique called x-ray fluorescent spectroscopy to analyze the painting. It turns out that the artist painted his work on top of another unknown artist’s painting of a landscape, and incorporated the landscape’s forms into the woman’s figure. You can sort of see the landscape by flipping the painting 90 degrees to the left.
