The Science of Cupules

Abstract

As the apparently simplest of all petroglyphs, cupules are shown to be scientifically and culturally very complex phenomena. Despite being the most common motif in rock art, their meaning or purpose remains largely unknown. This paper explores their physical and production properties, including their technology, taphonomy, morphology, biomechanics and energy investment involved, leading to the formulation of the production coefficient. The various quantifiable factors involved in cupule production are examined, including the phenomenon of kinetic energy metamorphosis (KEM). The tribological products, tectonite laminae, a new geological phenomenon first identified in cupules, offer the possibilities of developing a direct dating method as well explaining several related geological features.
