In 2004, during joint Australian-Vietnamese excavations of the site of Dong Xa, we unearthed a Bronze Age boat-coffin belonging to the Dongson culture. While Dongson coffins had previously been found in Vietnam, the find was significant. It contained a woman dressed in several layers of clothing and wrapped in a woven shroud, the first for Southeast Asia; fibres being the most fragile of all organics. It was not an accidental find; we targeted an irrigation canal where waterlogged remains would be preserved in anaerobic conditions. The discovery was significant to the Vietnamese who see the Dongson as the ancient Viet.
