An Son

There have been five major excavation projects since 1987 in An Son. The three most significant of these occurred in 1997, 2004, and 2009.

The 2009 excavation yielded an abundance of artifacts illuminating different cultural aspects of An Son. Specifically, animal bones and plant remains provide evidence for the subsistence economy that existed during the period of occupation.[3] In addition, excavation of ceramic remains, specifically pottery, provided information not only on the cultural substance of the population, but also led to predictions of intra- and inter-regional relations and origins of the population.[4][5]

Archaeologists were able to study the site of An Son due to material artifacts that indicated a timeline in which a civilization existed. Excavations found stone adzes, which are axe-like Neolithic tools made out of stone used for cutting material or food sources, giving archaeologists a better understanding of the time period and the technological advancements at An Son.

Another common artifact found at An Son is pottery remains. Pottery at the site was decorated with intricate patterns, showcasing their makers' skill.[1] Pottery was often used for cooking, storing, or serving food. While the use for pottery typically remained the same, the designs over the course of time improved and became more intricate. In the 1997 excavation, Nishimura Masanari and Nguyen Kim Dung found pottery that had different decorations, indicating development of new techniques and tools resulting in more intricate designs over a period of time. In the 2009 excavation, archaeologists expected to find more pottery vessel remains but instead found tools for puncturing and incising the pottery.[1]

The subsistence economy in An Son was characterized primarily by dog and pig husbandry. In addition to evidence for rice cultivation,[2] the majority of the evidence for subsistence economy came from the excavation in 2009, when archaeologists used biometric and age profiling analysis of 8610 animal bones found within the different layers of a trench.[3] Within this trench the majority of bones uncovered were those of dog and pig.

An Son is located in the southeastern part of Vietnam, close to other civilizations in Vietnam and Cambodia. Due to the proximity of An Son to other sites, research provided insight into relations and interactions with other regions, helping understand certain behaviors or cultural styles that civilizations exchanged. From material culture, archaeologists have been able to determine a correspondence between An Son and two other early Neolithic sites, Bau Too and Nong Nor. Nong Nor's ceramic vessels suggest strong similarities to the vessels found at An Son. They shared many characteristics, although artifacts at An Son were rare.

Another piece of evidence that hints at cultural exchange is the use of roulette stamping on vessels at An Son. Roulette stamping is a decorative technique used frequently on ceramic vessels. Although An Son's material culture shows ceramics were often incised and impressed which is common throughout Southeast Asia, roulette stamping shows potential communication with other cultures or civilizations. Widespread Neolithic culture in Southern Vietnam led to innovation across civilizations shortly after settlement at sites.[1]

Archaeologists have found some of the best evidence for subsistence strategies at An Son. The site is home to some of the earliest sedentary agriculturists in southern Vietnam. Excavations that have resulted in proof of agricultural sites have been used to determine the timing and dates of the introduction of domesticating animals in other areas in Vietnam. Archaeologists have been able to determine the interactions between the site of An Son and other sites around mainland Southeast Asia. For example, the substance strategy differs from those found in Northeastern Thailand, however the ceramics found at the An Son site shows similarities to Thailand ceramic techniques. The similarities and differences An Son had to areas in and around Vietnam show the interaction with other civilizations.[3]

An Son is one of the most extensively excavated sites in Southern Vietnam that provides evidence of a Neolithic sequence. Excavations occurred over the course of a decade that increased knowledge of the people of An Son, while also permitting comparison of its Neolithic culture to other regions and the timeline of other civilizations.[1]

One of the important discoveries in the site was the discovery of domestic dog bones in the earliest layers. Currently there is no earlier evidence of domestic dogs in the Hoabinhian culture in southern Vietnam. Therefore, evidence of domestic dog bones in the early layers of the site of An Son during the early Neolithic period indicate that domestic dogs were most likely introduced to the area by the earliest agriculturalists in the region.[3]

In addition, An Son exemplifies the rapid adaptation and local innovation of Neolithic culture in Southern Vietnam. The introduction of Neolithic type ceramics, advanced rice cultivation, and the domestication of animals were all found very early in the layers of the site. This indicates that all of these adaptations co-occurred. In addition, this site also demonstrates regionalization and innovation of Neolithic culture at the local level.[4]

Finally, An Son is also significant in terms of its place in the cultural heritage of Southern Vietnam. This site provides one of the earliest evidence demonstrating a well developed culture in Southern Vietnam. While this site was only occupied for a short period of time, the material culture[6] demonstrates both a strong tie to other regions as well as indigenous identity. The clear importance of this site is demonstrated by the interest from the Center for Vietnamese and Inter-cultural Studies in Hanoi, Vietnam. The Center funded and led the excavation in 1997.[1]
