It can be argued that Javanese literature started in Central Java. The oldest-known literary work in the Javanese language is the inscription of Sivagrha from Kedu Plain. This inscription, which is from 856 AD, is written as a "kakawin" or Javanese poetry with Indian metres. The oldest of narrative poems, "Kakawin Ramayana", which tells the well-known story of Ramayana, is believed to have come from Central Java. It can be safely assumed that this "kakawin" were written in the central Java region in the 9th century.
