• What was inside these pottery vessels 3,000 years ago?

In Peninsular Malaysia, researchers have found something unexpected preserved in prehistoric pottery: traces of milk.

A new study analysed 15 pottery fragments from three archaeological cave sites—Gua Cha, Gua Kajang and Gua Harimau—using techniques that can identify microscopic traces of foods absorbed into ceramics.

Among the substances detected were caseins and β-lactoglobulin, proteins found in milk. Their presence provides the earliest direct evidence yet reported for dairy processing in equatorial Mainland Southeast Asia, dating to around 3,000 years ago.

Archaeologists have long struggled to establish when farming and animal domestication became part of life in prehistoric Peninsular Malaysia. Unlike sites further north in Southeast Asia, clear evidence of early livestock management and cultivation has been difficult to find here, partly because animal bones and plant remains are often poorly preserved.

The milk proteins suggest that Neolithic communities were processing dairy products thousands of years ago. This does not necessarily mean they were raising dairy animals locally but it provides an important new piece of evidence for understanding food production and consumption in the region.

The researchers also identified traces of plant and animal foods, suggesting that these vessels were used for a variety of food-processing activities.

  • One river in northern Vietnam has yielded a remarkable record of more than 2,000 years of boatbuilding.

From the bed of the Kinh Thầy River at Cầu Bình, researchers documented 23 boat remains, including eight virtually complete logboat hulls and fragments of bows, sterns and planks. Radiocarbon dates place most of them between roughly 700 BCE and 1500 CE. 

Many hulls showed signs of sophisticated work beyond simply hollowing out a tree trunk. The hulls could be widened during manufacture, while wooden thwarts or bulkheads helped maintain their expanded shape. Some boats also carried additional boards along their upper edges, attached through holes with fibre lashings.

Around 2,000 years ago, during the late Đông Sơn and Han periods, several examples reveal another solution: mortise-and-tenon joints locked with wooden dowels. One boat even combined these joints with lashing holes. In later centuries, other Cầu Bình boats were built without this particular system.

This shows that over 2,200 years, boatbuilders used, combined and abandoned different solutions while continuing a long tradition of wooden river craft in the northern Red River Delta.

  • A 4.38-metre-long wooden rudder from the west coast of Sumatra is providing a rare glimpse of Southeast Asian seafaring around 1,300 years ago.

The rudder was recovered at the Bongal Site in Central Tapanuli, North Sumatra. Today the site lies inland, but geomorphological research suggests that in the 7th–8th centuries CE it was part of a shallow bay or estuarine environment.

The quarter rudder was carved from a single log and measures 4.38 metres long. Radiocarbon dating of the wood produced a calibrated date of 656–687 CE, making it the earliest securely dated rudder currently known from Southeast Asia.

Researchers also documented hull planks with raised wooden lugs, dowels and surviving palm-fibre ropes. These suggest that parts of these boats were pegged and tied together—a construction method archaeologists call the Southeast Asian lashed-lug tradition. Differences between the surviving planks even suggest that several vessels may have been present. 

Bongal also produced ceramics, glass, beads and coins pointing to connections with much wider exchange networks. The researchers do not argue that the Bongal boats themselves were making long-distance voyages across the Indian Ocean, but propose that locally constructed vessels formed part of a regional maritime network, moving through rivers and along Sumatra’s coast and connecting communities there to broader systems of exchange.

  • People in Sulawesi may have been habitually using a neuroactive plant as far back as 25,000–16,000 years ago.

A new study in Science Advances examines two preagricultural foragers from South Sulawesi, Indonesia, separated by thousands of years but sharing an unusual dental pattern: deep, rounded, circumferential wear that does not match ordinary chewing. The researchers argue that the wear formed through repeatedly holding, sucking or gently gnawing a small, hard object in different parts of the mouth. 

Using LC-MS, the team detected arecoline—a characteristic alkaloid of areca, or “betel”, nut—in dental samples from both individuals. One came from Leang Bulu Bettue and dates to 25–16 ka; the other, from Leang Cappalombo 1, is associated with deposits dating to around 7.6–6.3 ka. 

This was probably not betel chewing in the form familiar today. Modern betel quid typically combines processed areca nut with slaked lime and other ingredients. To test whether a simpler practice was plausible, the researchers soaked intact areca nuts and applied the resulting solutions to cells expressing human receptors. The experiments showed that intact nuts could release physiologically active arecoline without slaked lime. Combined with the dental wear, chemical residues and experiments support the authors’ interpretation that these foragers habitually sucked whole areca nuts.

For now, the sample is just two individuals, and psuggestions that the nuts were used for stimulation, pain relief or medicinal purposes remain hypotheses. What the study does show is that habitual neuroactive plant use may reach far deeper into the hunter-gatherer past than the archaeological record had previously demonstrated.

  • Twenty-two small beads can preserve the traces of a much larger world of movement and exchange.

A new archaeometric study examines beads excavated in 2023 at Khok Phithak, within the ancient city of Khu Bua in Ratchaburi, central Thailand. Khu Bua was an important urban centre associated with the Dvaravatī cultural sphere, enclosed by earthen ramparts and moats and situated within the Mae Klong river system. 

The researchers analysed 21 glass beads and one chalcedony/agate bead, combining microscopic observations with VP-SEM-EDS, LA-ICP-MS and micro-Raman spectroscopy. Manufacturing traces—including axial colour streaks and elongated bubbles—indicate that most of the glass beads were made by drawing glass into tubes or canes before cutting them into individual beads. 

Their chemistry indicates that nineteen beads belong to the m-Na-Al-1 glass subgroup, consistent with glassmaking traditions documented in South Asia, particularly the wider technological sphere of southern India and Sri Lanka. Together with their manufacturing technique, the authors associate these beads with the large-scale Indo-Pacific beadmaking tradition. 

However, one blue bead, B014, is made from plant-ash soda–lime glass with a broad western Asian affinity—although the study cannot identify a specific production centre. Another remarkable bead, B007, appears to have been wound from recycled iron-smelting slag, suggesting an entirely different production history.

Rather than evidence for primary glassmaking at Khu Bua itself, the authors interpret the assemblage as reflecting an inland centre of consumption and possibly redistribution, connected through maritime and riverine networks to much wider systems of Indian Ocean exchange.

Running facial recognition scans on the apsaras of Angkor Wat

Last year, independent researcher Kent Davis made the news with his theory that Angkor temples were a monument to women and to this end was hoping to analyse and quantify the traits of every apsara/devata image (over 1,700 in all). The Phnom Penh Post recently carried an update on Davis and his work and features, quite prominently, the discussion that on this website about Davis’ work (which you can read here).

What didn’t really come through in the PPP article was the paper on the facial pattern recognition study presented at the International Conference on Pattern Recognition in Istanbul, Turkey (it was buried somewhere in the middle of the article). The Cambodian Daily has a better-written paper on the article which you can read on Davis’ site, along with a download link to the facial recognition paper. The work is still very much in a preliminary stage, but quite promising and may potentially find correlations between types of faces with ethnicities or locations within the temple complex. It will be interesting to see what kinds of patterns emerge from a deeper analysis of the quantified attributes of the apsara/devata carvings emerge.

Sleuth researches enigmatic Angkor girls

Florida-based researcher, publisher and robot manufacturer Kent Davis is rapidly gaining an international reputation as the sleuth of Siem Reap, a new age detective delving into what he sees as one of the greatest mysteries of ancient Angkor Wat – the 1780 images of anonymous and mostly bare-breasted women depicted in carvings throughout the iconic structure.

Commonly known as apsaras (or, as Davis prefers, devatas), these female images were mostly accorded little significance.

But Davis, a former resident of Siem Reap and a regular visitor to Temple Town, is sure he’s onto something. He’s sure that these women represent something decidedly significant, but he’s not quite sure what.

Who are they, he asks, and why are there so many of them depicted throughout the great Khmer temple, not to mention other temples in the Angkorian complex?

Davis is now bristling with excitement because he has science on his side, and he’s certain that soon some answers will be revealed.

  1. Kent Davis says:
    16 years ago

    Thank you for covering this story. I look forward to more lively dialogs with SEAArch readers. As you note above, once again the Phnom Penh Post has produced a “casual” article written to appeal to general readers.

    Reporter Michelle Vachon with the Cambodia Daily, however, produced a more in depth article examining the facial pattern recognition study and the implications to other experts. I received permission to reproduce the Cambodia Daily’s copyrighted article and it appears on Devata.org. There is also a link to download the Michigan State University abstract.

    While it’s fun to debate various theories about who the women portrayed in the Khmer monuments may represent, I do encourage readers to do their own research (i.e. news articles are almost certainly NOT 100% accurate. Ever.)

    As for myself I am investigating based on three simple premises:

    1. The quantity, diversity and complexity of Khmer female images clearly indicate (to me) that they represent an extraordinary resource of cultural, historical, anthropological and spiritual information about civilizations flourishing in 12th century Asia.

    2. This resource has all but been ignored during the past 150 years of Khmer studies.

    3. My goal is to study, interpret and respect the images while protecting and preserving them for future generations.

    Whether they are queens, yoginis, temple guardians, real or imaginary women, idealized angels of heaven, random faces based on girls the stone carvers saw at the market, wives of the king or ancient Khmer leaders is not clear at this point.

    Based on everything I’ve seen and learned over the past five years of research it would be quite risky for anyone to stubbornly support any one of those interpretations.

    What is clear is that they were extremely important to the civilization that created these temples.

    I am confident that there *are* very specific and surprising answers to this mystery. I hope some of the theories develop here on your site.
