The Austronesian Painting Traditions (APT) are the most common types of rock art in Island Southeast Asia. They consist of scenes and pictograms typically found in rock shelters and caves near coastal areas. They are characteristically rendered in red ochre pigments for the earlier forms, later sometimes superseded by paintings done in black charcoal pigments. Their sites are mostly clustered in Eastern Indonesia and Island Melanesia, although a few examples can be found in the rest of Island Southeast Asia. Their occurrence has a high correlation to Austronesian-speaking areas, further evidenced by the appearance of metal (bronze) artifacts in the paintings. They are mostly found near the coastlines. Their common motifs include hand stencils, "sun-ray" designs, boats, and active human figures with headdresses or weapons and other paraphernalia. They also feature geometric motifs similar to the motifs of the Austronesian Engraving Style. Some paintings are also associated with traces of human burials and funerary rites, including ship burials. The representations of boats themselves are believed to be connected to the widespread "ship of the dead" Austronesian funerary practices.
