"Four and Twenty (Block Series)" is a monumental four-part sculptural work by Ron Davis executed in polyester resin and fiberglass, materials that became central to his exploration of three dimensional form during the 1960s and 1970s. The work exemplifies Davis's interest in geometric abstraction and his innovative use of industrial materials to create bold, architectural interventions in space. The title's reference to the nursery rhyme "Sing a Song of Sixpence" contrasts playfully with the work's austere, modernist aesthetic.
