This puppet, known as the 'kajon' or 'the tree of life', is said to be the most important puppet in the Javanese 'wayang kulit', or leather shadow puppet theatre tradition. The kajon is used in different ways to represent the beginning and the end of the scene. It can also be used to represent a forest or mountain, known as 'gunungan'. Wayang kulit is considered the highest of the performing arts. Performed in the royal courts of Java as early as the ninth century, this tradition continues to be treasured as one of the pusaka or sacred heirlooms of the court. Wayang kulit is traditionally performed on ritual feast days and religious ceremonies. It has also been adapted for television and public education campaigns.
