Jayavarman VII (11251215) was a king (reigned c.1181-1215) of the Khmer Empireat Angkor. Cambodia. He was the son of King Dharanindravarman II (r. 1150-1160) and Queen Sri Jayarajacudamani. He married Jayarajadevi and then, after her death, married her sister Indradevi. The two women are commonly thought to have been a great inspiration to him, particularly in his unusual devotion to Buddhism, as only one prior Khmer king had been a Buddhist. Over the 30 some years of his reign, Jayavarman embarked on a grand program of construction that included both public works and monuments. As a Mahayana Buddhist, his declared aim was to alleviate the suffering of his people. One inscription tells us, 'He suffered from the illnesses of his subjects more than from his own; the pain that affected men's bodies was for him a spiritual pain, and thus more piercing'. This declaration must be read in light of the undeniable fact that the numerous monuments erected by Jayavarman must have required the labor of thousands of workers, and that Jayavarman's reign was marked by the centralization of the state and the herding of people into ever greater population centers. Historians have identified three stages in Jayavarman's building program. In the first stage, he focussed on useful constructions, such as hospitals, rest houses along the roads, and reservoirs. Thereafter, he built a pair of temples in honor of his parents: Ta Prohm in honor of his mother and Preah Khan in honor of his father. Finally, he constructed his own 'temple-mountain' at Bayon and developed the city of Angkor Thom around it. He also built Neak Pean ('Coiled Serpent'), one of the smallest but most beautiful temples in the Angkor complex, a fountain with four surrounding ponds set on an island in that artificial lake.
