Bronze lion door-guardians. There are altogether twelve, in six pairs. It had been believed that the pair guarding the main central door of the ordination hall on the east, which can be entered only by the Chief of State, was brought from Cambodia by command of King Rama I and the rest were copied in that reign. However, Professor Boisselier, the renowned French expert on Khmer Art, examined the central pair of lion-guardians and concluded that the design on their chest is Thai in style rather than Khmer. They probably were cast by Thai artisans copying Khmer lions. On both sides of the main staircase in front of the Royal Pantheon on the east sit two stone lion-guardians. Though they have been very much restored, one can perceive that they belong to the Khmer Bayon style (about the early thirteenth century A.D.). Therefore it might be that this pair of stone lions was brought from Cambodia during the reign of King Rama I and the bronze ones were cast in that reign to copy them.
