Bob Duggan reveals the story behind the exhibition George Inness in Italy at the Philadelphia Museum of Art through May 15, 2011. The ten painting exhibition centers around Inness' painting Twilight on the Campagna (1851). Duggan writes: "Twilight on the Campagna was one of those hidden treasures languishing in the darkness for want of wall space, [it] is now the centerpiece of their exhibition… Inness’ Twilight began with his own treasure hunting, specifically a sojourn to Italy in search of artistry of the past he could take and transform into a new type of painting for the future."
