Canadian archeologist Dougald O’Reilly and his team were widely credited with solving the mysteries surround the Plain of Jars in northeast Laos, a vast megalithic landscape of massive stone jars scattered in clusters, dating to the Iron Age, around 500 BCE to 500 CE. O’Reilly, a professor at the Australian National University in Canberra, has also released his latest book "Empires of the Southern Ocean," which traces state-level societies across Southeast Asia, encompassing modern-day Myanmar, Malaysia, Indonesia, Cambodia, Thailand, and Vietnam.
