It's hard to believe that this gorgeous bit of painting by Francisco de Goya, held at the Carnegie Museum of Art since 1965, has only been on view now and then. But that's because it hasn't always been acknowledged as the Spaniard's work. This is about to change, as new research just about proves that the Pittsburgh painting is by him.

The prestigious "Burlington Magazine" is getting ready to publish an article, by the late art historian John Williams, that shows that Goya used the Carnegie piece to help him paint his great fresco around the base of the dome at the chapel of San Antonio de la Florida in Madrid, where he finished working in 1798.
