SALT LAKE CITY — New tools originally designed for medicine, manufacturing and geology helped a team of researchers discover the paintings underneath some of Pablo Picasso’s earlier works, according to The New York Times.

The researchers, who presented their findings on Saturday during a meeting of the American Association of the Advancement of Science in Austin, Texas, discovered a little bit more about Picasso’s method of painting.

For example, X-ray images uncovered that Picasso painted the 1902 painting “La Miséreuse accroupie,” (“The Crouching Woman”) over another piece of art.

But Sandra Webster-Cook, who works at the Art Gallery of Ontario in Toronto, discovered that the painting had another texture underneath, which didn’t represent either of the two paintings before it.

Using the aforementioned technology, researchers at National Gallery of Art, Northwestern University and the Art Institute of Chicago discovered that Picasso tried to paint a woman’s arm before he painted "The Crouching Woman."

“So this again is getting into the mind of the artist and understanding his creative process,” said Marc Walton, a research professor of materials science and engineering at Northwestern, to The New York Times.
