The oldest known record that probably concerns wayang is from the 9th century. Around 860 CE an Old Javanese (Kawi) charter issued by Maharaja Sri Lokapala mentions three sorts of performers: atapukan, aringgit, and abanol. Ringgit is described in an 11th-century Javanese poem as a leather shadow figure. An inscription dated 930 CE says si Galigi mawayang ("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. The kakawin Arjunawiwaha composed by Mpu Kanwa, the poet of Airlangga's court of Kahuripan kingdom, in 1035 CE describes santoṣâhĕlĕtan kĕlir sira sakêng sang hyang Jagatkāraṇa, which means "He is steadfast and just a wayang screen away from the 'Mover of the World'. " Kelir is Javanese word for wayang screen, the verse eloquently comparing actual life to a wayang performance where the almighty Jagatkāraṇa (the mover of the world) as the ultimate dalang (puppet master) is just a thin screen away from us mortals. This reference to wayang as shadow plays suggested that wayang performance is already familiar in Airlangga's court and wayang tradition has been established in Java, perhaps earlier. An inscription from this period also mentioned some occupations as awayang and aringgit.
