One more from Van Gogh

Art historians had known of the Van Gogh drawing, stored at the Van Gogh Museum in Amsterdam. But they had always wondered whether it was a copy of a completed painting.

Now, at last, the painting itself has been discovered concealed under another painting in the Museum of Fine Arts in Boston, the Van Gogh Museum said.

The work, Wild Vegetation, painted in June 1889, was discovered in an x-ray of The Ravine, which Van Gogh painted on the same canvas four months later, the museum said.

"One of our specialists looked at the x-ray and recognised it as resembling a drawing from the museum," said Natalie Bos, a spokeswoman for the Van Gogh Museum.

The museum called the discovery important for researchers and said it would display the drawing, done in brown reed pen, in Amsterdam as part of an exhibition of Van Gogh’s drawings running until October 7.

Vincent Van Gogh often sent drawings of his painted works to his brother Theo, an art dealer in Paris. The artist, who sold few paintings during his lifetime, relied on Theo to send him supplies, and painted new compositions over his old work if the materials arrived late and he lacked the money to buy his own.

At the time Wild Vegetation was painted, Van Gogh was confined at the Saint-Remy asylum in southern France. Armed with fresh materials from Theo, he was allowed off the hospital grounds and painted the surrounding landscape, including his famous series Wheatfields. — AP
