This installation consists of 15 individual sculptures in the form of ants situated in the sunken garden at the front of Taylor Hall. The ants are in procession from the middle point of the garden towards the west wall. The sculptures are made from bent rebar and bent sheets of steel. Each has a central horizontal rod that has curved elements for the head and tail attached at either end. The thorax is also made from a piece of curved steel that is braced with a metal rod and a fin on the underside. Welded to the middle section are three bent pieces of wire on either side. While all of the ants appear similar, it appears as if each was made by hand so there are small differences on each element, most noticeably in the curve of the mouth. There are twelve ants on the ground and three attached to the wall. These three have their legs secured to the brick wall with cement. The twelve on the ground are at rest in the gravel. A plaque near the eastern end of the procession reads: “David Bowen / “Procession of Ants” / Herron School of Art”.
