Washington: Home of the Nation's Great Staff Photographer Rlobert F. Sisson Classic Domes Crown the Federal Capitols of Art (Right) and Government Into the National Gallery of Art went 800 carloads of rose-white marble; rain brings out its strawberry glow. Not a window pierces the gallery spaces. Sunbeams fall through the skylight roof. In gloomy weather floodlights gleam in the attic. Both kinds of lighting are diffused by case-hardened glass. If it breaks, it crumbles into octagonal fragments harmless to paintings. Humidity is kept constant to protect canvases from injurious expansion and shrinkage. In the distance, Freedom's 19-foot figure surmounts the Capitol (Plate I).
