LoRAP and TAP collaboration
From 1986 to 1994 the Thai-American ‘Thailand Archaeometallurgy Project’ (TAP), co-directed by Surapol Natapintu (formerly Thai Fine Arts Department) and Vincent C. Pigott (MASCA-University of Pennsylvania), excavated three sites in the Khao Wong Phrachan Valley: Non Pa Wai, Nil Kham Haeng and Non Mak La (Khok Samrong District, Lopburi Prov.) (Fig.s 1-2).
The Italian-Thai LoRAP, in addition to having participated in the stratigraphic investigations at the three sites, has established a close relationship of scientific collaboration with the TAP aimed at defining the first chronological and cultural sequence of the prehistory and protohistory of Central Thailand (ca. early 2nd millennium BCE – end of 1st millennium CE).
In the KWPV sites the stratigraphic investigations revealed a complex sequence of phases of human activities ranging from the Neolithic (c. 2000-1100 BCE) to the Dvaravati Period (c. 600-1000 CE) (Fig. 3).
