The megalithic burials of southern India—a wonderfully varied set of monuments—have long needed a chronology and a context. Broadly contemporary with the Roman and Sasanian empires, these dolmens, cairns and cists have continually raised contradictions with their material contents. The authors attack the problem using luminescence applied to pottery at the site of Siruthavoor in north-east Tamilnadu. Although sharing material culture, this first pilot project gave dates ranging from 300 BC to AD 600, so exposing the problem and perhaps, in OSL, its long-term solution.
