Virginia Overton’s new sculpture Untitled (chime) is assembled from salvaged tools and discarded metal parts. Suspended from an I-beam by steel cables, each object has a counterpart equal in its weight, with which it forms an equilibrium. As Overton says: ‘I use geometry as a way of understanding space. Balance is so important.’ These varied and imperfect objects create a visual contrast to the strong, architectural lines of the I-beam, itself a gateway that echoes the arched doorways and trellises of the walled gardens beyond. Overton’s sculpture is played by the wind, but visitors are also invited to reach up and sound the instrument by hand.
