The construction sequence described above is almost in harmony with the change of pediment end styles from pediments ending in scrolls made from one block, to pediments ending in scrolls made from two blocks, and finally to pediments ending in five-headed nagas.
It was clarified that during the construction of Preah Vihear, the style of pediment ends changed from pediments ending in scrolls made from one block, to pediments ending in scrolls made from two blocks, and finally to pediments ending in five-headed nagas.
The scroll style pediment ends can be subdivided into pediments that end in scrolls made from one block (Fig. 4a) and those that end in scrolls made from two blocks (Fig. 4b, c, e), yielding three distinct pediment end styles.
Pediments that end in scrolls made from one block are found in all these buildings.
