The main stupa in the city of Nakhorn Pathom ifself is belived to have been built to commemorate the advent of the Venerable Theras and to enshrine the Buddha’s relics brought by them, Another source associates it with King Praya Parn of a much later date, i.e. the U-tong period (circa 12th-15th century A.D.). [23] His father, Praya Kong, was the King of Kanchanaburi.The court astrologer predicted, when he was but a baby, that he would kill his father when he grew up.The king, obsessed by the fear of the prospective assassination,decided to nip it in bud and passed death sentence on the son. But the boy escaped death; his mother stealthily stole him away and entrusted him to an old lady, Yai Horm. When the boy came of age, she dedicated him to the sevice of the king of Ratchaburi. As fate would have it, it was during this period that praya Kong marched his army against the kingdom. Praya Parn, as the young exiled prince was then known, led his defence force and, ignorant of his own origin, killed his father in the battlefield. The prediction thus came true, But the killing did not stop there. Learning from his mother the story of his birth, he fell upon poor Yai Horm, accusing her of concealing from him the truth and keeping him in ignorance as to who his real father. Praya Parnm, however, later repented the atrocities and wanted to make atonement for the crimes; he was advised to build a pagoda “as high as the flight of a turtle dove”. But, according to the tradition,. He could not afford to carry out the instruction to the letter and had to be satisfied with a more convenient and less expensive course by erecting a Prang (Pinnacle) on the top of an existent stupa, giving thereby an appearance of the required height. [24] This stupa has been identified with pra pathom chedi and the story gives us a hint of its existence in the remote past. [25]
