The extensive charcoal cave art at the Gura Sireh Cave on the island of Borneo appears to reflect decades of frontier violence, according to a new analysis.
Cave art continued in Southeast Asia until the relatively recent past, the new paper says. Scientists carbon-dated some of Gura Sireh’s drawings to a period between 1670 and 1830. At the time, the indigenous hill tribes, the Bidayuh, suffered at the hands of the local Malay elites, who ruled the countryside.
