Alexander Calder at Pace Gallery

The art of constructing mobiles is a mathematical exercise. Creating a well balanced suspended sculpture requires the artist to calculate the appropriate distances for each of the weighted elements. “Calder Small Sphere and Heavy Sphere” is the inaugural exhibition at Pace’s new palatial gallery in Chelsea.

This “Untitled” Mobile from 1932 features four white spheres of various sizes and one tiny red sphere. The spheres are attached to ends of suspended rods.

For this Untitled Mobile from 1934 Calder seems to create an almost impossible equilibrium. The top rod has a single solid form suspended on the left and a second rod suspended on the right. From the second rod there two more suspended forms.
