What lies beneath (the art): new technology allows a glimpse beneath the surface of paintings. From the article:

Researchers in the US have used a new scanning technique to discover a painting underneath one of Pablo Picasso’s great works of art, the Crouching Woman (La Misereuse Accroupie)….

Details were revealed at the annual meeting of the American Association for the Advancement for Science in Austin, Texas….

What is remarkable is that the landscape painting beneath – probably by a student artist – is turned 90 degrees. The outline of the hills in the background becomes the crouching woman’s back. She takes on the shape and form of the Catalan countryside.

Kenneth Brummel, a curator at the Art Gallery of Ontario in Toronto, said that he was “excited” when he first learned what lay underneath the Crouching Woman.

“It helps to date the painting and it also helps to determine where the painting was made,” he told BBC News.

“But it also gives a sense of the artists with whom the painter was engaging. And these insights help us ask new, more interesting and scientifically more accurate questions regarding an artist, their process and how they arrived at the forms that we see on the surface of a painting.”
