The above slide is from the Gordon & Enid Minter Slides Archive, which comprises 100s of slides accompanied by various hand written lectures. This particular slide details a sandstone post situated at the side of Wakefield Road in the area of Flockton, West Yorkshire. In that post there is a deep groove, made by an 18th Century pulley system for hauling coal trucks back up the hill once they had sent their goods down to the canal at Horbury Bridge as part of an industrial tram system. Hollows, grooves, gaps, clefts, absences, marks, lancuna, tunnels, voids, depressions, cavities, excavations, pits. Everything I have engaged with in this archive relates to sculpture and form; from the carved hollows underground to the apparatus built above ground to assist in the extraction and distribution of coal deposits. Thus, the artwork developed in response deals with absence and presence / negative and positive, while considering what these shapes might come to represent in a world deeply impacted by these historic site-based activites.
