Mpu Prapanca
Mpu Prapanca was a 14th-century Buddhist monk and poet at the Majapahit court in Java. In 1365 he composed the Nagarakretagama in Old Javanese as a eulogy to King Hayam Wuruk.
The epic portrays Majapahit at the height of its power, describing its capital, temples and vassal lands across the archipelago, and remains the chief source for the empire's history. He reportedly described himself as a former head of the kingdom's Buddhist clergy, a dharmadhyaksa kasogatan.
