4,000-year-old painted stone in Indonesia reveals symbolic art carried by ancient Austronesian maritime voyagers | World News
A small painted stone found on Indonesia’s Wetar Island is offering archaeologists a glimpse into the symbolic world of ancient seafarers. It dates to about 4,090 to 3,900 years ago and features a red design of concentric circles and radiating sun rays that is linked to the Austronesian Painting Tradition (APT). The discovery is significant because the artwork was mainly known from cave and rockshelter walls. Research published in PNAS titled ‘4000-year-old painted plaque from Southeast Indonesia reveals Austronesian Painting Tradition preceded Neolithic pottery’ provides the earliest known example of the tradition.Researchers say it also changes the picture of what Austronesian voyagers carried as they moved between islands. Their journeys involved more than technologies, possessions and economic practices. Shared symbols and ideas may also have travelled with them, helping communities express identity, affiliation and beliefs during one of prehistory’s most extensive human dispersals.
4,000-year-old painted plaque found on Indonesia’s Wetar Island
The painted plaque was discovered during excavations at Huknaur rockshelter on Wetar Island in Indonesia. It was recovered in situ from a transitional archaeological layer between Palaeolithic and Neolithic occupation. The stone carries a red design made of concentric circles and radiating lines, described as a sun-ray motif. Researchers identify this pattern as a characteristic of the Austronesian Painting Tradition, an artistic tradition found across eastern Indonesia and parts of the Western Pacific. Unlike most known APT paintings, which appear on cave or rockshelter walls, this example was made on a portable object. Its archaeological context is important because it provides a secure date for the motif and shows that APT imagery existed on movable objects and surfaces.

Radiocarbon dating places the ancient plaque before Neolithic pottery
Radiocarbon dating indicates that the plaque dates to between 4,090 and 3,900 calibrated years ago. This makes the object older than the first pottery found at the site. The plaque was discovered in a preceramic layer, showing that the Austronesian Painting Tradition was present on Wetar before pottery became a material marker used to trace Austronesian expansion. The researchers connect this early date with the movement of Austronesian-speaking peoples across Island Southeast Asia. The finding supports an early origin for the APT and suggests that symbolic traditions were already established during the earliest phases of maritime expansion, rather than emerging only during later periods of intensified inter-island contact. This gives archaeologists a clearer picture of early APT development.
Portable art may have helped ancient Austronesian symbols travel
The portable nature of the plaque shows how ancient symbols travelled. A painting in a cave wall remains in one place, while a painted object can move with people from one island to another. The researchers suggest that portable symbols may have helped communicate shared identities, affiliations and beliefs between communities. Similar sun-like designs were historically painted on boats and other objects, where they could serve as symbols of protection and group identity.The plaque does not prove exactly how this particular design was used, but its existence shows that APT imagery was not limited to rock surfaces. It provides material evidence that symbolic expression could make art a part of the traditions carried by maritime communities widely. The finding therefore adds another dimension to understanding how cultural ideas may have travelled alongside people during ancient ocean voyages.
What the painted stone reveals about Austronesian expansion
The Austronesian dispersal was a major human migration in prehistory, with descendants of populations associated with Taiwan eventually reaching islands across a vast area, from Madagascar to Rapa Nui. At the site, the plaque was found in a frontier layer that lacked typical Austronesian ceramics but contained novel elements, including bead types associated with Austronesians.The researchers argue that ideology may have been important at the wavefront of expansion. The plaque points to a movement in which people carried not only practical knowledge and possessions, but also shared artistic traditions and symbolic ideas widely.
