"These screenprints were adapted from drawings Knowles originally made as preparatory studies for his sculpture, but which he also considers separate works. The source drawings were made of geometrical shapes cut from brightly coloured paper collaged onto graph paper in a variety of arrangements. The composition of 'S.24.02' includes four circles of solid colour in black, blue, yellow and green, and four parts of circles, two green and one each in blue and yellow. These are placed irregularly over schematic outlines of circles, defined in black ink." - quotation Tate
