The theory, for a long era held as fact, was to be contested by Louis Finot, supported by the discovery that the monument was in outlook toward of fact Buddhist. Some controversy followed, successively leading Mr Philippe Stern - partner conservator of the Muse Guimet - to place the Bayon, based mainly vis--vis a investigation of the interchange styles, in the first half of the 11th century - and later Georges Coedes, through epigraphic research, to attribute the set in motion to king Jayavarman VII at the fade away of the 12th century. This proclamation in 1928 rejuvenated the Bayon by three centuries, revolutionised the settlement of its chronology - attributing its faults no longer to the explorative beginnings of Khmer art but rather to the flagging discipline of the decadent era - and with shattered a number of architectural, decorative and religious anomalies. Today the adding together theory can be considered as generally accepted and apparently definitive. It was Mr Victor Goloubew who brought the aeration to a decisive conclusion in imitation of his meticulous research into the appointment of the capitals. By in flames intuition he ceased looking for the Central Mountain of the inscription inside Angkor Thom and otherwise focused his attention regarding the Shivate temple-mountain of Phnom Bakheng, construct going on just to the south upon a natural hill. Excavations from 1931 to 1934 revealed the remains of enclosure walls, of gopuras, of grand axial roads and of symmetrically arranged pools - all framed within a double levee of earth forming a quadrilateral that is yet quite visible in the landscape. The location of the first Angkor was for that excuse appreciative to be quite independent of Angkor Thom and the Bayon of Jayavarman VII. Other excavations, undertaken in 1936, have enabled Mr Goloubew to suggest the existence of option intermediate capital, dating perhaps from the 11th century and centred upon Phimeanakas or the Baphuon - or else upon the first site of the Bayon. It would have had moats at its limits, lined once than laterite steps, together in the middle of two levees of earth formed at a hundred metres within the parentage of the unfriendly ramparts of Angkor Thom. Other canals have been found upon either side of the principal axial roads as ably as the remains of gates and drainage channels, confirming anew the particular importance that hydraulic works had for the ancient Khmer, for whom water constituted such a snappish element.
