claimed as the descendant of a king that ruled Java. The short peace The Mataram kings after Pikatan; from Lokapala, Watuhumalang (r. 890–898) and Balitung are the patrons of Shaivite Hinduism, "after the decline of the power of the Buddhist Shailendras in central Java." Their reign seems to enjoyed a relative peace. The grand Shivagrha temple compound are continuously expanded and completed with hundreds of perwara (complementary) temples surrounding the main three prasada (tower) of Trimurti Hindu Gods. It is probably during their reign that some Hindu temples are constructed in the area, such as Sambisari, Barong, Ijo, Kedulan, Kimpulan, Kadisoka, Gebang and Merak temple. Barong and Ijo temples in particular are interesting, for they are built on the hill and has different layout compared to earlier temples. Sewu and Prambanan temples are arranged in concentric mandala layout. Barong and Ijo temples, however, are arranged in a completely different way; the main temple is located further back of the compound on the most higher ground, while the perwara complementary temples are built in front of the main temple on the lower ground, the layout corresponds to the uneven topography of the site. This style of temple layout is most likely the predecessor and will be continued in the later East Javanese temple architecture. King Pikatan, Lokapala (Rakai Kayuwangi), and Watuhumalang ruled from their court in Mamrati or Amrati, they are known as "Amrati Kings". The exact location of Mamrati is unknown, suggested somewhere in Kedu Plain (modern day Magelang and Temanggung regencies), located north from Mataram along Progo River valley. It was suggested that Amrati might be located near the location of Wanua Tengah III inscription, in Kedunglo hamlet, Kaloran village, within Temanggung Regency. After absent for several generations, the name "Mataram" reappears in Javanese inscription during the reign of Balitung, which probably signify the transfer of capital. King Balitung moved his capital from Amrati to Poh Pitu, and renamed Poh Pitu as Yawapura. Again the exact location of this capital is unknown, probably also located within Kedu Plain. However, it is highly possible that Poh Pitu was located around the Poh inscription (905), in Dumpoh hamlet, Potrobangsan village, North Magelang district within Magelang city. Balitung productively issued several inscriptions, among others are Telahap inscription (dated 11 September 899), Watukura inscription (27 July 902), Telang (11 January 904), Poh (17 July 905), Kubu-Kubu (17 October 905), Mantyasih (11 April 907),
