Art of the Ancestors: Spatial and temporal patterning in the ceiling rock art of Nawarla Gabarnmang, Arnhem Land, Australia

This volume presents a new systematic approach to the archaeological recording and documentation of rock art developed to analyse the spatial and temporal structure of complex rock art panels. Focusing on the ceiling art at Nawarla Gabarnmang, one of the richest rock art sites in Arnhem Land the approach utilised DStretch-enhanced photographs to record 1391 motifs from 42 separate art panels across the ceiling. Harris Matrices were then built to show the sequence of superimpositions for each art panel. Using common attributes, including features identified by Morellian Method (a Fine Art method not previously employed in archaeological rock art studies), contemporaneous motifs within panels were then aggregated into individual layers. The art layers of the various panels were then inter-related using the relative and absolute chronological evidence to produce a full relative sequence for the site as a whole. This provided a story of the art that began some 13,000 years ago and concluded around 60 years ago, with a major change identified in the art some 450 years ago. The method was shown to be invaluable to the resolution of many difficult issues associated with the identification of motifs, their superimpositions and the development of art sequences.
