nly historical scene, a procession of Suryavarman II, then the 32 hells and 37 heavens of Hindu mythology.
On the eastern gallery is one of the most celebrated scenes, the Churning of the Sea of Milk, showing 92 asuras and 88 devas using the serpent Vasuki to churn the sea under Vishnu's direction (Mannikka counts only 91 asuras, and explains the asymmetrical numbers as representing the number of days from the winter solstice to the spring equinox, and from the equinox to the summer solstice). It is followed by Vishnu defeating asuras (a 16th-century addition). The northern gallery shows Krishna's victory over Bana (where according to Glaize, "The workmanship is at its worst") and a battle between the Hindu gods and asuras. The north-west and south-west corner pavilions both feature much smaller-scale scenes, some unidentified but most from the Ramayana or the life of Krishna.
Construction techniques
The stones, as smooth as polished marble, were laid without mortar with very tight joints that were sometimes hard to find. The blocks were held together by mortise and tenon joints in some cases, while in others they used dovetails and gravity. The blocks were presumably put in place by a combination of elephants, coir ropes, pulleys and bamboo scaffolding. Henri Mouhot noted that most of the blocks had holes 2.5 cm in diameter and 3 cm deep, with more holes on the larger blocks. Some scholars have suggested that these were used to join them together with iron rods, but others claim they were used to hold temporary pegs to help manoeuvre them into place.
The monument was made out of enormous amounts of sandstone, as much as Khafre's pyramid in Egypt (over 5 million tons). This sandstone had to be transported from Mount Kulen, a quarry approximately 25 miles (40 km) to the northeast. The stone was presumably transported by raft along the Siem Reap river. This would have to
