The sculpture is constructed in planar form in stainless steel and is the second sculpture in that material after Callipyge. The horse was initially modelled in plaster. Over that the planar steel was welded in sections, so it would release from the plaster former then welded back together. Welding the rods around the head was the most complex as they are so small. I had to hold them in place with tweezers whilst welding and trying not to weld the tweezers to the sculpture. The horse is implied to be running although the legs are not totally realised. Aesthetically the head and barrel-like body were of more interest and I saw no need to finish the legs. The title comes from the Mares of Diomedes, four man-eating horses which Heracles was tasked to steal. Exhibited at the Crypt Gallery and Birtley House.
