The vaulted ceilings of the galleries are raised 6 metres from the ground; those of the second roof are 4 metres 30 centimetres high. The two roofs are supported by a double row of columns, the first being 3 metres 18 centimetres and the second 2 metres 25 centimetres high by 48 centimetres broad. The columns are square, and, like all other buildings in the province, are formed of single blocks. There are five staircases on the west side, the same number on the east, and three on each of the remaining sides. The basement is 3 metres 90 centimetres in height, the length externally forming a terrace of 1 metre 67 centimetres. Each portico is composed of three roofs raised one above the other, which contribute materially to give to the architecture of these long galleries a monumental appearance, producing a singularly beautiful effect. The opposite side of the wall to the double colonnade is, from the lowest row of cornices to one metre above its base, covered inside with bas-reliefs, having externally blank windows with balustrades. [Illustration: CARVINGS OF ARMS, UTENSILS, AND ORNAMENTS, AT ONGCOR-WAT] There are two rows of cornices, the first part immediately above the columns; and the space, to the extent of nearly one metre, which lies between them, is filled up by roses and other sculptured designs. BAS-RELIEFS. The bas-reliefs represent the combat of the king of the apes with the king of the angels:[24] in the centre is the king of the angels, drawn by two griffins; he has seven heads and twenty arms, with a sabre in each hand. Some of the chiefs are seated in cars drawn by fabulous animals, while others are mounted on elephants. The soldiers are armed with bows, javelins, or sabres, but the apes have generally no weapons except their formidable claws: a few of them have clubs, sabres, or branches of trees. [24] These sculptures probably represent the story of the Hindu Ramdyana, of great reputation among Buddhist nations. The _angel_ is Ramana, Tyrant of Ceylon; and the King of the Monkeys, Hanuman, Rama’s General. _Peristyle No. 1._--Here is represented the march of warriors mounted on birds, horses, tigers, and fabulous animals; the horses of the chiefs are led by the bridle. On the right the soldiers are advancing towards the scene of combat in the centre; but here there are no fantastic animals. _Peristyle No. 2._--The bas-reliefs of this peristyle represent the combat between the king of the apes and the king of the angels, and the death of the former. Close by is a boat filled with rowers, all with long beards, and some of them attired in the Chinese fashion: the group is admirable for the natural positions and for the expression given to the faces. A cock-fight, and women at play with their children, are also represented. It is in these bas-reliefs that the highest degree of skill is shown. Other subjects follow, the meaning of which I could not discover.
