If you had to pin a label on New York sculptor Joel Shapiro you could call him a magical minimalist. The sculptures he is showing at the Baltimore Museum of Art are modernist, Manhattanesque, reductionist, enchanted. The magic happens all at once.

You're looking at a piece composed of three, or five, or seven connected blocks of wood or bronze. You've seen such forms before. You're thinking, as you think you should, gray and formal thoughts of additive assemblage, emptiness and Euclid, when suddenly the spell takes hold. All at once -- there's someone there!

That beam's become a human leg, that wedge a human torso. When glimpsed from the right angle, Shapiro's mute and boxy forms start behaving just like people. One is crouching in the corner in a mood of deep dejection. Some are striding through the gallery, or somersaulting gaily. Some are gliding as if skating. You've felt them come alive.
