A Dong Son bronze spear and an axe found near the coastline may suggest that the ancient peoples of that culture may have interacted with the sea more than previously thought. I do find the conclusions of the archaeologist in the article stretching a bit too thin when he says that the discovery of the artefacts prove that there was trading activity going on near the sea though.
Artifacts further evidence of East Sea sovereignty: expert
Vietnam Net Bridge, 07 July 2009
The two Dong Son artifacts discovered in Ha Tinh Province late last month reaffirm Vietnamâ€™s sovereignty over the East Sea area, says Trinh Sinh, an official of the Institute of Archeology.
The Dong Son culture was centered in the Red River valley in northern Vietnam and was a prehistoric Bronze Age culture, dated to about 2000 BC-200 AD.
According to Ha Tinh Provinceâ€™s Department of Culture, Sports and Tourism, farmers in the village of Ky Loi in Ky Anh District, discovered on June 22 two artifacts that experts believe date back two millennia.
The artifacts, a bronze spear and an axe, were found on the Vung Ang seabed, about two kilometers off the coast of Ky Loi Village.
â€œThis is the first time weâ€™ve discovered Dong Son artifacts near the seabed,â€ Sinh said. â€œThis proves that the residents of Dong Son culture had conducted trading activities near the sea area that borders their land.â€
