Legends of Nakhon Chai Si City and Phra Praton Chedi ฺBefore the establishment of the chief city of Kamalanka,
Nakhon Pathom, previously known as Nakhon Chai Si (), there was already a Brahmin village in this area called “Tona Brahmin”. The village was built around a stone house that Brahmins enshrined "
Tona" () or the golden bowl used to measure the Buddha's relics. The legendary texts of
Phraya Maha Akkanikorn () and
Nai Thong () state that this event occurred in 590 CE. The city of
Nakhon Chai Si was later founded in the same area by King
Siddhijaya Brahmadeva (), who was from the city of
Manohan or
Manohana () near the border of the city of
Yatsothon (). The king later set Nakhon Chai Si as a new chief city. During this era, this polity established their relations with
Sri Lanka via
Buddhism; however, after the conflict with the local Brahmin, the king relocated the city 4 kilometers westward to the present-day
Phra Pathommachedi area and named the city
Pawan or
Panan () In another version composed by Aong mentions King Sakata () of
Takkasila set the new era,
Chula Sakarat, in 590 CE, which was the same year that the Brahmins of
Tona Brahmin village enshrined a "
Tona" in the stone house. His successor, Phraya Kawanadit Thera (), expelled those Brahmins to
Lavo in 650. Even though the versions of
Phraya Maha Akkanikorn and
Nai Thong say Kawanadit Thera was instead the King of Lavo, all versions mention Kawanadit Thera built a
chedi to cover the stone house containing the
tona and named it
Phra Prathon Chedi in 656, which conforms to the text given in the Ayutthaya version of the Traibhumi Picture Book (). Their son was
Khun Borom, However, previous scholars believe
Khun Borom originated from
Xiangkhouang in Laos or some
mueang in southern China. one of the
Dvaravati polities. They then waged wars against
Tou Yuan to the northwest, Some suggests that the son of
Si Thep king named Bhavavarman mentioned in the Ban Wang Pai Inscription (K. 978) founded in the
Phetchabun province of Thailand was probably
Bhavavarman II instead of
Bhavavarman I (r. 580–598) due to the inscription styles that potentially inscribed after 627. The aforementioned royal intermarriage may have enabled another son of Kakabatr named
Kalavarnadisharaja to establish his polity, known as the
Lavo Kingdom, in the eastern
Menam Valley in 648, a year after
Dvaravati won over
Tou Yuan.
Legend of Phraya Kong – Phraya Pan The legend of , which provides slightly different details in each version, has been told in the western
Chao Phraya region. The story begins with a line of
Sikaraj, king of Srivijaya (,
Nakhon Pathom; says an ancient
Kanchanaburi) whose power extent south to
Ratchaburi. His son,
Kong, succeeded him. Due to the prophecy that his son would kill him,
Kong ordered his newborn son to be killed, but his queen consort secretly gave the child to a commoner named
Yai Hom (; ), who named the boy
Pan ().
Pan was later adopted by the king of
Ratchaburi, who stopped paying tribute to King
Kong on
Pan's suggestion, causing
Kong to attack Ratchaburi, but unfortunately was slaughtered by
Pan in the battle.
Pan was enthroned as the king of Srivijaya, and after he realized that
Kong was his father,
Pan built a large
chedi, which is believed to be the
Phra Pathommachedi, atoning for his sin. Some say that it was adapted from a Sanskrit fable, which in turn was derived from the Greek
Oedipus. The other two versions by Phraya Ratchasamparakorn () and Ta Pakhao Rot () say that after
Pan was adopted by the King of Ratchaburi, he then travelled north to
Sukhothai, where he also became the adoptive son of the king of Sukhothai. With Sukhothai's support, he moved south and overthrew
Kong at Nakhon Pathom. The and
Jinakalamali additionally provide the expansion of the influence of
Pan northward and being enthroned as the king of
Haripuñjaya during 913–916, while the southern territory in the western
Menam Valley was overthrown by his adoptive father, King of
Ratchaburi.
