Javanese Mountains
The mountains of central Java include the neighbouring volcanic cones of Sundoro and Sumbing, rising between the Dieng highlands and the Kedu plain. A gap between the peaks carried an old route from Kedu toward Wonosobo and Dieng. In the late fifteenth-century Sundanese account of Bujangga Manik, Dieng, Sindara and Kedu appear as inhabited holy mountains. Their slopes and the valleys between them formed part of the landscape of the early kingdom of Mataram.
