Erotic Nudes, Satyrs Frolic in Philadelphia Exhibit

The mythic Greek valley Arcadia, a harmonic realm balancing dignity with desire, is an enduring source for artists and the subject of a pleasurable exhibition, “Gauguin, Cezanne, Matisse: Visions of Arcadia,” at the Philadelphia Museum of Art.

At the entrance to the show, which opened yesterday, is a long, narrow, light-green hallway that functions like an intimate, shaded glen.
