The legend of the establishment of Phra Pathom
There are only a few issues, all related to the names "Nakhon Chai Si" and “Phra Praton Chedi,” "Phra Pathom Chedi," “Phraya Kong,” and “Phraya Phan.” These names appear in documents including the Northern Chronicles, the Phra Pathom Chedi Legend, the Phra Prathon Chedi Legend, the Phraya Maha Araknikorn version, the Nai Thong version, the Phraya Ratchasamphanakon version, the Tapakhao Rot version, and the version of Nai Ong Waikalang (Fine Arts Department 1985). These documents tell similar stories but are undated. The stories mentioned across the various documents can be categorized into two main narratives: the story of Nakhon Chai Si and Phra Pathom Chedi, and the story of Phra Pathom Chedi and Phraya Kong-Phraya Phan. Below is the story of Phra Pathom Chedi and Phraya Kong-Phraya Phan. [5]
The story takes place during the Dvaravati period, spanning from the 7th to the 11th century CE, when Chai Sri was still a coastal city in the Gulf of Thailand. The history of Phra Pathom Chedi is narrated and recorded differently. It generally follows that Phraya Kong was the ruler of an area around Nakhon Chai Sri. The ruler of Rat Buri was a tributary to Nakhon Chai Sri. Phraya Kong's queen became pregnant, and the royal soothsayer predicted that if the child were a son, he would kill his father and take the throne. Like Moses, the newborn was placed in a basket in the river and left to be found.
A woman named Yai Hom (grandmother Hom), who raised ducks along the river, found the baby and named him Phan. Phan grew up to be an intelligent man, became a favourite of the ruler of Rat Buri, and was eventually adopted as his son.
Phan, seeing the yearly tributes of gold and silver presented to the ruler of Nakhon Chai Sri, offered to wage war against the latter to free Rat Buri. The ruler of Rat Buri consented, and Phan, with a large army, launched an attack on Nakhon Chai Sri. Phan besieged the city, killed his father, Phraya Kong, and tried to take the queen for his wife. The queen recognised her son at a scar on his forehead, and Phan finally discovered the truth. Enraged, he killed Hom, the woman he was raised by, for not telling him the truth.
Becoming suddenly conscious of his wrong actions, Phraya Phan ordered the construction of two stupas in an act of expiating his sins: one stupa in memory of his father, the Phra Pathom Chedi, and the Phra Prathon Chedi for Yai Hom. Both chedis remain very important until the end of the Ayutthaya period.
