The art of Neolithic Britain and Ireland consists of a variety of curvilinear and geometric motifs pecked into stone (in open-air rock art or passage tombs) or carved into portable artefacts of chalk, stone or antler. Because of its abstract nature the art has proved problematic for archaeologists. Initially archaeologists assumed the art was representational; now most scholars have abandoned this view, and simply approach the art stylistically. Here I argue that stylistic analysis is insufficient to understand this art: instead the process of making provides a fuller understanding of this art. It is argued that the practice of assemblage is a key aspect of the process of making.
