Kentucky-based sculptor Dale Graham uses his background in mathematics and engineering to create sculptures that make us aware of the principles governing the creation of structures and bridges. This aluminum sculpture features a trunnion, a cylindrical pin like that on a cannon that forms the axis on which it pivots, a device also used in bridge design. Graham chose to use lightweight aluminum instead of heavy steel so that his sculpture could be more easily transported from place to place. He burnished the surface of the sculpture so that it reflects light in irregular patterns adding to the “lightness” of the piece.
This sculpture has been donated to the Skokie Northshore Sculpture Park by the artist and is now part of the Park’s permanent collection.
