Traditional Thai paintings showed subjects in two dimensions without perspective. The size of each element in the picture reflected its degree of importance. The primary technique of composition is that of apportioning areas: the main elements are isolated from each other by space transformers. This eliminated the intermediate ground, which would otherwise imply perspective. Perspective was introduced only as a result of Western influence in the mid-19th century.
The most frequent narrative subjects for paintings were or are: the Jataka stories, episodes from the life of the Buddha, the Buddhist heavens and hells, themes derived from the Thai versions of the Ramayana and Mahabharata, not to mention scenes of daily life. Some of the scenes are influenced by Thai folklore instead of following strict Buddhist iconography.
