Wayang is a generic term denoting traditional theatre in Indonesia. There is no evidence that wayang existed before Hinduism came to Southeast Asia sometime in the first century CE brought in by Indian traders. However, there very well may have been indigenous storytelling traditions that had a profound impact on the development of the traditional puppet theatre. The first record of a wayang performance is from an inscription dated 930 CE which says “si Galigi mawayang,” or “Sir Galigi played wayang”. From that time till today it seems certain features of traditional puppet theatre have remained. Galigi was an itinerant performer who was requested to perform for a special royal occasion. At that event he performed a story about the hero Bhima from the Mahabharata.
