Javanese epic poem written in 1365 by Prapañcā. Considered the most important work of the vernacular literature that developed in the Majapahit era, the poem venerates King Hayam Wuruk (reigned 1350–89) and gives a detailed account of life in his kingdom. It also includes information about King Kertanagara (reigned 1268–92), great-grandfather of Hayam Wuruk.
