Prohear, Cambodia
Prohear is an archaeological site from the Early Iron Age located in the Prey Veng province of Cambodia between the capital city of Phnom Penh and the border with Vietnam. By the time the site became known to archaeologists in 2007, it had been heavily looted and few archaeological materials remained. Prohear is known for its burials and uniquely rich array of grave goods including numerous precious metal artifacts. A number of the artifacts excavated at the site have contributed to the study of trade routes that connected Prohear to the rest of Southeast Asia.
History of the site
Prohear was active during the Iron Age, with burials at the site being dated to a period between 200 BC and 100 AD. At this point in time in Southeast Asia, inhabitants of the region lived in smaller farming communities that predated the development of larger centralized nation-states.Discovery
In 2007, villagers in the town of Prohear discovered the presence of ancient artifacts and began to purposefully dig for them with the intention of selling them. Local archaeology students attempted to intervene, but by the time formal excavations were organized, the majority of the burials in the cemetery had been looted. The only part of the site that remained mostly untouched was an area that lay beneath the main road running through the village. A series of rescue excavations were conducted in 2008, 2009, and 2011 with the goal of preserving as much of the remaining archaeological record at the site as possible.Archaeology
The excavations conducted at Prohear were a collaboration between the German Archaeological Institute, based in Berlin and the Memot Centre for Archaeology in Cambodia.Environmental conditions
Cambodia has a tropical climate with warm temperatures and high moisture levels. Annual cycles of monsoon winds dictate weather patterns; winds blowing from the southwest from mid-summer to mid-fall carry torrential rains while winds blowing from the northeast carry less moisture and initiate a dry season from fall to spring. The high humidity creates obstacles to the preservation of organic materials, which limits what archaeologists in the region are able to study.Burials
76 burial complexes were excavated at Prohear that were consistent with other Bronze and Iron Age burial sites in the region, dating to around 150 BC to 50 AD. Individuals were buried lying on their backs. Wealthier individuals were buried with richer grave goods; there are several examples of wealthier individuals buried with their heads inside the bronze drums characteristic of the region or beneath bronze disks. These burial circumstances might have indicated the importance of the individuals within the community.Due to the environmental conditions at the site, there was generally very poor preservation of human skeletal remains, greatly limiting the analysis that the researchers could conduct. Instead, they focused on dental remains, finding evidence that the people who lived in the area were generally healthy, despite the expected high rate of child mortality. The dental remains showed significant wear due to extensive use of the teeth, demonstrating patterns consistent with living in farming communities. There was also evidence found of cultural modification practices such as tooth blackening, a practice that is still followed in different Southeast Asian communities.
