• 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.

Apirak wants Unesco to list Rattanakosin

SUPOJ WANCHAROEN

Bangkok Governor Apirak Kosayodhin plans to push for the listing of the old Rattanakosin area in Bangkok as a World Heritage Site, like the old city of Luang Prabang in Laos.

Mr Apirak said he was confident he could persuade the United Nations Educational, Scientific and Cultural Organisation, or Unesco, to declare the Rattanakosin area in Phra Nakhon district, an inner precinct of Bangkok, as a World Heritage Site.

”In the Rattanakosin area, we have the Grand Palace and temples with long histories. What we will do is renovate buildings and houses in this area to bring them into harmony with the old structures and revive the culture and traditional way of living of Bangkok residents,” he said.

”For instance, there will be a morning market in that community, or regular alms-giving. With these things, the area will have sufficient potential to become a World Heritage Site.”

Deputy city clerk Anant Siripasaraporn said tourist revenue would increase if the area was listed as a World Heritage Site. World Heritage sites draw many foreign tourists.

”The important thing is to encourage residents to conserve their culture. Income from tourists should be generated among them, not fall into the hands of merchants or businessmen.”

Mr Apirak came up with the World Heritage idea after taking executives of the Bangkok Metropolitan Administration (BMA) to visit Laos from June 11-13.

Khampheng Saysompheng, vice-governor of Luang Prabang province and president of the local heritage committee, said Luang Prabang had been proposed to Unesco since 1987. The province was declared a World Heritage Site in 1995.

Normally, old towns with historical values such as Cambodia’s Angkor Wat would not take as long to be listed as World Heritage sites, he said.

For Luang Prabang, Unesco had to consider the town’s traditional way of living which was culturally significant and worthy of protection.

”Unesco wants to evaluate how long we can preserve our traditional way of living,” he said.

Now Luang Prabang makes US$80 million a year from tourism. Ten years ago, only 60,000 tourists visited the town a year, but that has now increased to 300,000, he said. The number of tourists is expected to increase to 500,000 a year in the next 10 years.

Mr Apirak said he would find ways to draw tourists to visit both Bangkok and Luang Prabang as a tour package.

    Strangely, already in 2005 that area was submitted to UNESCO for consideration as a future world heritage site – see this Nation article: http://nationmultimedia.com/search/page.arcview.php?clid=3&id=112421 Only at that time it wasn’t the whole Rattanakosin island, just a “scenic strip of the Chao Phraya river” between the Memorial Bridge (at the southern end of Rattanakosin island) and Wasukri Pier, further north than the island, which ends at the Pinklao Bridge. Which sites this was supposed to include I have no idea. I haven’t heard anything of this proposal ever since.

    There are even more World Heritage recent proposals – three northern Thai towns, the Chao Phraya area already mentioned, and Srivijaya remains in the south. http://www.bangkokpost.com/170608_News/17Jun2008_news15.php
