This article reports on the discovery of a new rock art site from East Timor that is located inland on the southern flanks of the central mountainous spine of the island. One particular painted motif, a socketed axe with haft, indicates that at least some of the motifs were painted c. 2000 b.p. This date and the stylistic and technical features of the art would place it within the later body of painted art associated with the Austronesian Painting Tradition (APT) elsewhere in the western Pacific. This later phase is characterized by greater diversity in style, color, and placement of motifs than is found in the earlier APT. Comparison with the other known art sites in East Timor shows significant di¤erences between the rock art of the eastern and central parts of East Timor, indicating that these areas comprised separate stylistic regions.
