When the baby was very small, still in what I have often heard termed the “fourth trimester,” an out-of-town relative came to visit the baby, and to visit New York, and so one afternoon, the baby was put into the sling and was in this manner transported through a Magritte show at the Museum of Modern Art. The baby’s sling consisted of two loops of black fabric, the one nestling into the other, and the baby was still so small that her feet didn’t stick out, nothing showed of her save her bald head, and sometimes, a tiny hand gripping at the edge of the fabric. The paintings at the Magritte show included: men whose heads had been replaced by apples, a gathering of legs without bodies, an iris that was a clouded sky. Magritte-type images, naturally. Magritte’s stated goal, the museum copy noted, was to make “everyday objects shriek aloud.” In one exhibition room after another after another, a stranger would catch sight of the bald head, the small hand, floating amidst a vanishing cloak of sling and raincoat. One stranger after another said of the baby’s inadvertent performance art, “That’s my favorite piece in the show.”
