In 1873 Edouard Manet finished his famous and beautiful “Railroad” painting. In it a woman in a blue travel coat, sitting on the stone base of a gate, stares us in the face, looking up from her book and gazing through us as if digesting what she just read, a little dog sleeping on her lap. Next to her a girl (her daughter?) stands with her back toward us, a big blue bow on her white Sunday dress, gripping the gate bars and looking through them at … a cloud of steam. No train in sight. They are waiting, for what, for whom? Perhaps the girl’s attention is not drawn by what she sees but by what she hears: a steam valve must be hissing loudly.
