Europe’s Oldest Archery Relics Unearthed in Spain

Anthropology.net

Archaeologists exploring the depths of Cueva de los Murciélagos, or "Bat Cave," in southern Spain have unearthed a remarkable discovery1: Europe’s oldest-known bowstrings and arrows, dating back between 7,200 and 6,900 years. These finely crafted remnants not only highlight advanced Neolithic technology but also provide a rare glimpse into the lives of early agricultural societies on the Iberian Peninsula.

A Cave of Many Histories

Cueva de los Murciélagos has long been a site of fascination. Nestled in Granada province, the cave was once mined for bat guano and lead-rich minerals, and its use as a necropolis dates back millennia. However, much of its archaeological record was plundered during the 19th century, leaving a fragmented legacy of funerary artifacts and skeletal remains.

Modern archaeologists have been piecing together the cave’s history from the scattered remnants left behind. Among these are tools and weaponry that reveal the ingenuity of the Neolithic communities who laid their dead to rest in its chambers.

“The discovery of these bowstrings and arrows marks a significant milestone in our understanding of early European craftsmanship,” notes Raquel Piqué, senior author of the study and researcher at the Autonomous University of Barcelona (UAB).

The Bowstrings: Twisted Threads of History

Among the cave’s most extraordinary finds are two bowstrings crafted from braided animal tendons—a technique still employed by modern archers. Initially thought to be made from plant fibers, detailed spectroscopic analysis revealed their true composition: collagen derived from roe deer, goats, and possibly wild boar.

“The manufacturing technique is identical, despite the raw materials differing across centuries,” explains Ingrid Bertin, a French archaeologist and co-author of the study. “This continuity suggests a shared knowledge of crafting techniques that persisted across generations.”

The bowstrings provide unique insight into Neolithic technology. Unlike stone tools, organic materials like tendon rarely survive the passage of time. Their discovery highlights the sophisticated craftsmanship of early Iberian communities and offers a rare example of prehistoric organic tool preservation.

Neolithic Arrows: Light, Swift, and Deadly

Accompanying the bowstrings were arrow shafts crafted from reed and wild olive wood, the latter prized for its hardness and density. Many arrows retained their feathered fletching, which helped stabilize flight, and were tipped with points secured by birch tar, a natural adhesive produced by slow-cooking tree bark.

“The use of reeds for arrow shafts in prehistoric Europe was hypothesized for decades, but this discovery finally confirms it,” says Piqué.

Birch tar’s presence also offers an intriguing avenue for future research. The adhesive may contain traces of ancient DNA, potentially providing clues about the individuals who crafted and used these tools.

Hunting or Warfare? The Dual Purpose of Archery

The purpose of these arrows remains uncertain. The Neolithic people who inhabited the Iberian Peninsula were primarily agriculturalists and herders, but they still engaged in hunting and possibly warfare.

“In life, these arrows could have been used for hunting or combat. Cave paintings from the region depict scenes of interpersonal violence, suggesting a dual purpose,” says Francisco Martínez Sevilla, head of the Murciélagos Project at the University of Alcalá.

The symbolic role of the cave as a burial site adds another layer of complexity. The dead were placed on the cave floor along with funerary offerings, creating a collective, evolving memorial that spanned millennia.

A Lost Treasure Trove

Unfortunately, much of the cave’s archaeological legacy was lost to miners in the 19th century. Precious artifacts, including a gold tiara, were plundered, and bones were repurposed to reinforce paths.

“The greed of the miners destroyed much of the site’s historical value, but ongoing excavations are recovering items that shed light on the Iberian Peninsula’s first Neolithic inhabitants,” laments Martínez Sevilla.

Despite these losses, the discovery of these archery artifacts underscores the enduring ingenuity of early human societies.

Looking Ahead: The Future of Neolithic Research

Researchers plan to replicate the arrows and test their effectiveness, offering insights into the practical applications of these ancient tools. Additionally, efforts to extract ancient DNA from birch tar could unlock new details about the lives of those who crafted and wielded these weapons.

The study also raises questions about how knowledge was transmitted across generations in the Neolithic period. The continuity of bowstring manufacturing techniques suggests a deeply ingrained cultural tradition, one that persisted through centuries of change.

As the story of Cueva de los Murciélagos continues to unfold, its artifacts provide a powerful reminder of the ingenuity and adaptability of our ancestors.
