By the beginning of first millennium, Buddhism has been firmly established in the area of Thailand, Burma, Java and Cambodia. Buddhism develops art and architectures as visual aids for propagation of the religious ideas in South-east Asia. Buddhist stylistic arts have given the great impacts on the religious and secular life of the people in those related areas for more than two millenniums and thus Buddhism had created a great current of art in south-east Asia. Under this artistic trend, many valuable art works created and gave rise to emerge a special social phenomenon. Thus, the paper focuses on the influence and impact of Indian Buddhist art on south-east Asian art and the dimensions of Buddhist art in south-east Asian culture. This paper also compares the Buddhist art in the homeland of Buddhism with those in other Buddhist countries in south-east Asia and examines the dissemination of Buddhism through art and Architecture.
