Oldest known monument might prove public veneration predates agriculture

August 21, 2021

When archaeologist Klaus Schmidt first began excavating on a Turkish mountaintop, he was convinced the buildings he uncovered were unique.

Atop a limestone plateau near Urfa called Gobekli Tepe, Turkish for "Belly Hill", Schmidt discovered more than 20 circular stone enclosures. The largest was 20m across, a circle of stone with two elaborately carved pillars 5.5m tall at its centre. The carved stone pillars – eerie, stylised human figures with folded hands and fox-pelt belts – weighed up to 10 tons.

Carving and erecting them must have been a tremendous technical challenge for people who hadn't yet domesticated animals or invented pottery, let alone metal tools. The structures were 11,000 years old, or more, making them humanity's oldest known monumental structures, built not for shelter but for some other purpose.

After a decade of work, Schmidt reached a remarkable conclusion.

The stone tools and other evidence Schmidt and his team found at the site showed that the circular enclosures had been built by hunter-gatherers, living off the land the way humans had since before the last Ice Age. Tens of thousands of animal bones that were uncovered were from wild species, and there was no evidence of domesticated grains or other plants.

Schmidt thought that small, nomadic bands from across the region were motivated by their beliefs to join forces on the hilltop for periodic building projects, hold great feasts and then scatter again. The site, Schmidt argued, was a ritual centre, perhaps some sort of burial or death cult complex, rather than a settlement.

If that was true, it showed that complex ritual and social organisation actually came before settlement and agriculture.
