This article puts forward two modes through which cognition and agency exist beyond skin: ‘layering’ and ‘networking’. These bodily and artefactual processes are broadly equivalent to two fundamental social practices defined by Chapman (2000) — accumulation and enchainment, respectively. While the aim of the article is to develop theoretical frameworks for application in archaeological settings, the themes encountered have wider relevance to material culture as a whole. Examples are taken from modern and contemporary art, notably the work of Marcel Duchamp and Antony Gormley.
