Rückriem began his career as a sculptor carving massive stone heads. One day he visited a quarry for the first time and was deeply struck by the presence of the raw stone. From then on his aim in sculpture was to reveal its natural power and beauty. This four part work emphasises the massive block-like character of the material. It was made by splitting or sawing the rock into simple harmonious proportions. It is fundamental to Rückriem that the separated pieces are reconstructed to form the original block. Here he has made three splits in each block of the Dolomite Stone in a sequence of variations. The splitting is done with a drill and a large chisel known as a bolster.
