Traditional Thai art is primarily composed of Buddhist art and scenes from the Indian epics. Traditional Thai sculpture almost exclusively depicts images of the Buddha. Traditional Thai paintings usually consist of book illustrations, and painted ornamentation of buildings such as palaces and temples.
The Sukhothai period began in the 14th century in the Sukhothai kingdom. Buddha images of the Sukhothai period are elegant, with sinuous bodies and slender, oval faces. This style emphasized the spiritual aspect of the Buddha, by omitting many small anatomical details. The effect was enhanced by the common practice of casting images in metal rather than them. This period saw the introduction of the "walking Buddha" pose. Everything has its own purposes.
Sukhothai artists tried to follow the canonical defining marks of a Buddha, as they are set out in ancient Pali texts:
Sukhothai also produced a large quantity of glazed ceramics in the Sawankhalok style, which were traded throughout south-east Asia.
The surviving art from this period was primarily executed in stone, characterised by juxtaposed rows of Buddha figures. In the middle period, Sukhothai influence dominated, with large bronze or brick and stucco Buddha images, as well as decorations of gold leaf in free-form designs on a lacquer background. The late period was more elaborate, with Buddha images in royal attire, set on decorative bases.
This period is characterized by the further development of the Ayutthaya style, rather than by more great innovation. One important element was the Krom Chang Sip Mu (Organization of the Ten Crafts), founded in Ayutthaya, which was responsible for improving the skills of the country's craftsmen. Paintings from the mid-19th century show the influence of Western art.
