Kakawin
Kakawin are long narrative poems composed in Old Javanese, also called " Kawi", written in verse form with rhythms and metres derived from Sanskrit literature. Poets used a formalized literary language, rather than the vernacular. Poets composed and performed the poems at the courts of central and east Java kings between the 9th and 16th centuries, and in Bali.
Although the poems depict events and characters from Hindu mythology, the narratives are set in the local landscapes of the islands. They are rich sources of information about courtly society in Java and Bali.
