89 ments of Siam, we mainly draw from these sources, supplemented by M. Fournerean's chapter on construc- tions in his Le Siam Ancfen (I, PP97-111). It seems that the domain of archaeology of Siarn Is vast. The Hindu colonies were established at different epochs in almost all parts of the kingdom. The documents of tiie extreme East, which help us to throw light on its obscure history, may be divided, according to M.Lajonquiere, into four groups} namely:- (:) IndoCambojan (ii) Hindu (Xon-Combojan) (::i) Siamese, and (iv) Laotine. We shall presently deal with the Hindu period, anterior to the foundation of Ayuthia ( A. D. 1350). \Ve cannot strictly draw a line of demarcation between the two ancient kingdoms of Camboja and Siam. The ancient Camboja at present comprises both (i) Camboja, under the French Protectorate, and ( 2) Siam proper. It should also be borne in mind that Siarn in the early centuries of the Christian Era had no separate existence. Therefore, in tracing the history of art in Siaro, we have to go back a little tc the pre-Siamese days, when the artistic development took place in Camboja. As the inscriptions in khmer and in Sanskrit (relating to Comboja) embrace the period from the sixth to ninth centuries, we can fix the extreme dates between which the artistic mani- festation of the Indo-Cambojaa school took place.
