This paper re-examines the concept of the archaeological event as a means to avoid dual or multiple levels for historical phenomena, which a scalar view of time creates. Central to this procedure is an examination of the nature of residuality in relation to the archaeological record; it is argued that our concept of residuality needs to be broadened to encompass a more general view of material organization where the property of reversibility is foregrounded. In doing so, a different conception of the event is generated which defines itself not in terms of particularity but reversibility.
