To many, for a very long time the Philadelphia Museum of Art has been an institutional manifestation of everything its classical architecture was meant to convey. August. Stalwart. Serious. Sitting a bit aloof on Fairmount above the rest of the city, the museum has always required you to make the first approach.
Nothing about the opening this month of the Ruth and Raymond G. Perelman Building - the first public addition since the opening of the neoclassical temple in the 1920s - makes the mission less serious. But the 173,000-square-foot expansion represents the museum's only suggestion in decades that its art is not necessarily tied to a building, and that it is ready to come down off its pedestal, literally and figuratively, to become part of a city neighborhood.
