The mundane image of Göbekli Tepe has just been erased, however, given the recent discovery of three carved human skulls within the ruins. The findings are reported in the journal Science Advances.
“It can be that the individuals were decapitated when still ‘fresh,’” lead author Julia Gresky of the German Archaeological Institute’s Department of Natural Sciences said.
“But,” she added, “it can also be that, like known burial customs of other Neolithic sites, the burials were reopened after some time, the skulls were taken and remnants of soft tissue that were still adhering to the bone were scraped away. Then the carvings were performed and the skulls were displayed.”
In short, the site was likely home to a Neolithic skull cult.
Skull cults refer to groups that practiced rituals involving the heads of the dead. The cults were sometimes peaceful and tied to ancestor veneration. The authors believe that carving “branded” the skulls, marking them as different from other human remains. But branding might instead have informed onlookers that these individuals were dead enemies.
The skulls at Göbekli Tepe lack collagen, Gresky said, but organic residues were found in the mud mortar and wall plaster residues near the remains. These were radiocarbon dated to what are known as the Pre-Pottery Neolithic A period (10,000-11,500 BC) and the Pre-Pottery Neolithic B period that followed and lasted until about 7,000 BC in this region. Göbekli Tepe is located 7 miles northeast of the city of Şanlıurfa, Turkey.
The adult ages of the individuals did not surprise the researchers.
“People who survived the critical periods in life, like childhood, and in women, the period of giving birth, had the chance to become quite old,” Gresky explained. “The average age in the Neolithic is low because of high infant mortality.”
