On Chronology-Building for Central Thailand Through an Attribute-Based Ceramic Seriation

This paper seeks to build a chronology for the prehistoric period and the early historic period of central Thailand. Sixteen ceramic assemblages from 14 prehistoric and early historic archaeological sites in the Pa Sak River valley (of central Thailand) were examined using an attribute-based seriation method. Body sherds were included in the study and the attributes selected for this study are those of surfacetreatment attributes. Correspondence analysis was used to seriate the 16 ceramic assemblages. Findings from this study suggest that surface-treatment attributes are temporally sensitive. The proposed chronology is thus based primarily on results of correspondence analysis of surface treatment. The final arrangement of the ceramic, asian perspectives, spring, assemblages corresponds closely to broad archaeological periods proposed previously by Southeast Asian archaeologists. The results of correspondence analysis, however, provide a finer-scaled chronology for the study area. This research thus contributes to a better understanding of chronological development in the Central Plain of Thailand in general and in the Pa Sak River valley in particular. The research shows the significance and efficacy of attribute-based seriation and correspondence analysis as an exploratory multivariate method in the chronological placement of archaeological assemblages in Thailand and, by extension, in Southeast Asia.
