When archaeologists began excavating a large ancient settlement near Tel Aviv in 2012, among the many discoveries at the 9000-year-old site were as many as 400 locally crafted artifacts made from obsidian.

One reason this was so significant is that this dark volcanic glass is absent in Northern Israel, and discoveries in the region ultimately helped trace it back to quarry sites in central Turkey. Although the importation of non-local source materials in the ancient world is not particularly unusual, another discovery archaeologists soon made proved more baffling: the appearance of unusual engravings on several arrowheads produced from this ancient Anatolian obsidian.

Now, a rare collection of these uniquely engraved projectiles is providing archaeologists with deeper insights into the presence of a mysterious symbolic tradition that was practiced long ago by some of the earliest farming communities 9,000 years ago.

The Mystery of Anatolia’s Engraved Arrowheads

In a recent study published in Plos One, an international research team examined a collection of eleven previously undocumented arrowheads unearthed at Tepecik-Çiftlik, a Neolithic settlement in Cappadocia. These ancient projectiles are each decorated with carefully carved incisions, the purpose of which remains baffling to archaeologists.

The rare discoveries have been grouped with an exceptionally uncommon class of ancient stone artifacts, which have only been found in Central Anatolia, and were only known to have been produced during the late eighth and seventh millennia BCE. With the inclusion of the new set, which became the focus of the team’s study, the total number of these unusual artifacts rises to 43 that have been documented across the region.

These projectile points are unique among arrowheads, which are one of the most common artifacts from the ancient world, since the purpose of their engravings remains unclear. A range of theories have been proposed, which include the idea that some may have been personal identifiers; other theories propose clan symbols, hunters’ marks, or even ritual or symbolic reasons for their presence on the ancient obsidian weapons.

Unraveling the Mystery

Study authors Alice Vinet and Denis Guilbeau took a cautionary approach, warning that current evidence remains insufficient to draw any firm conclusions about the unusual markings.

“The analysis of these incised arrowheads, along with the limited archaeological and ethnographic comparisons available, calls for a cautious interpretation,” the authors write.

To try to understand the possible meaning behind these markings, the researchers conducted a detailed analysis that examined technological, functional, and iconographic aspects of the markings. Based on macroscopic evaluations, the source of the obsidian was determined to likely come from volcanic sources at Göllüdağ and Nenezi Dağ in Turkey, both of which are recognized by archaeologists as sources of high-quality volcanic glass during the Neolithic.

Despite their simplicity, the engraved designs on the samples the team examined showed significant diversity. However, no consistent relationship emerged between the incisions and the raw materials used to craft the arrowheads; nor were any connections apparent regarding manufacturing techniques, shapes, or in terms of use patterns.

One potentially important observation was that some of the engravings appear to have been made before the tools were completed, while other examples showed signs of engraving after completion. This suggests there had been no standardized stage during production when the markings were applied that may provide clues in terms of a possible meaning behind the markings (such as a kind of label or other marking that might have been used to designate individual samples before being knapped into projectiles).

Despite the variations between samples, their overall comparison with other samples recovered from Central Anatolian sites in the region did appear to show recurring design components, suggesting continuity that could indicate a shared visual tradition that was incorporated across multiple ancient communities in the area.

Location Offers Clues

Another intriguing aspect of the team’s study involves the locations where they were recovered. As opposed to simply being found in ceremonial contexts, some of the projectiles were found in the remnants of homes, while others were found in lithic production sites or during archaeological surveys, which seems to suggest the engraved obsidian arrowheads saw use in a wide range of everyday activities and practices.

Still, based on their rarity and constrained geographic distribution, the persistence throughout several centuries of Anatolian prehistory seems to point to a unique cultural practice in the region, the full significance of which remains unknown. For now, their presence offers a unique look at the ancient hunters and farmers from one of the earliest settled societies, suggesting that even artifacts with largely practical uses may have held greater significance in terms of the symbolic importance they held for their ancient makers.

A discovery by archaeologists at the Pre-Pottery Neolithic site of Çemka Höyük in southeastern Turkey is extending the accepted timelines on the origins of ancient ceramic technology.

The discovery, detailed in a new study that appeared in the journal Antiquity, provides some of the earliest evidence yet uncovered for intentionally fired pottery in Southwest Asia. The findings appear to show that the first experimentation with ceramic technology began thousands of years earlier than once believed.

At the heart of the findings are a collection of more than 45 low-fired clay fragments, representing at least nine separate vessels, which researchers unearthed at the site of Çemka Höyük in Mardin Province. The fragments date to approximately 9,350 BC, placing them in a period that predates the widespread adoption of pottery during the seventh millennium BC by nearly two millennia.

The discovery offers an unprecedented glimpse into the earliest stages of ceramic innovation, adding to past discoveries that include early agricultural innovations and remarkably sophisticated monumental architecture associated with famous sites in the region like Göbekli Tepe.

An Ancient Experiment in Ceramics

Rather than evidence of full-scale pottery production, the new study by researchers Ergül Kodaş, Natalia Petrova, Maria Daghmehchi, and Rana Özbal argues that a period of experimentation seems to have begun around 11,500 years ago.

The nine vessels represented by the fragments uncovered at Çemka Höyük showcase simple slab-building techniques, where plant material, and even animal dung was sometimes mixed into the source clay to help improve its performance during the firing process. Further analysis of the samples indicated that they were intentionally heated in controlled, low-heat fires that reached temperatures of roughly 600 to 700 degrees Celsius, which produced permanent ceramic transformation, rather than mere accidental burning.

A Surprise Discovery

Along with the pottery fragments, archaeologists also discovered an unusual variety of clay objects at Çemka Höyük: a type of clay coating that may have once covered organic objects, along with an attachment formed from the same material that seems to have been used for enlarging the capacity of a vessel made from another material, such as stone or wood.

Altogether, the diversity of the artifacts the team uncovered points to strong evidence that early Neolithic communities in the region were already experimenting with clay in a range of different ways, before the widespread adoption of ceramic technologies for pottery production.

This is significant, since the discoveries challenge existing ideas about the emergence of pottery, which suggested that it was quickly adopted as a fully developed technology.

“This new evidence points to an early implementation and demonstrates that ceramic innovation emerged before widespread production and adoption,” the team writes, “developing regionally and progressively rather than through a single invention event.”

“Our analysis of the fired clay items from Çemka shows that the inhabitants of the site experimented with pottery production by selectively using organic temper, low-temperature firing technologies, and slab-construction techniques,” they add.

Ceramic Technology in the Ancient World

The study also places Çemka Höyük within a broader network of early clay experimentation across Southwest Asia. While similar finds have been reported from sites in Türkiye, Syria, Jordan, Iran, and Israel, the Çemka discoveries are now recognized as being among some of the oldest known examples of intentionally fired ceramic technology ever identified in the region.

Even beyond the technical implications of what the team outlines, the new study offers deeper perspectives on the social aspects of such innovations in the ancient world. For instance, to become successful, technologies must offer more than just functionality by becoming ingrained in the everyday lives of a culture.

The evidence suggests that at Çemka Höyük, use of clay underwent gradual transitions from use as a construction material to a medium used for storage and food preparation. This reflects changes in the culinary practices of the era, as well as certain community activities right down to the daily routines of Çemka Höyük’s ancient residents.

Thus, the early experiments outlined in the new study helped to lay the foundation for the sophisticated pottery use and other traditions that would ultimately make their way throughout the region, revolutionizing the ancient Near East with the arrival of one of its earliest technological revolutions.

The team’s new study, “Understanding a first attempt at pottery: early fired containers at Çemka Höyük,” appeared in the journal Antiquity.
