HOUSTON A Rice University professor s computational analysis of canvas helped lead to the discovery of a long-lostVanGogh.

Electrical and Computer Engineering Professor Don H. Johnson s analysis established the connection between a painting once thought to be a fake VincentVanGogh and a real Van Gogh, The Rocks, hanging at the Museum of Fine Arts Houston.

Johnson performed statistical analysis of X-ray images of the canvas behind the previously unknown Sunset at Montmajour and his research aided experts at theVanGogh Museumin Amsterdam in authenticating the painting. The painting s canvas was a match for The Rocks, which is owned by the MFAH.

TheVanGogh Museum unveiled its findings, along with the painting itself, in Amsterdam on Sept. 9.
