Phra Mongkhon Bophit or the “Buddha of the Holy and Supremely Auspicious
Reverence” was sculpted in 1538 in the reign of King Chairacha (r. 1534-1547) at Wat
Chi Chiang Sai. 1538 is generally accepted as the year that the image was built, based
on the Luang Prasoet version of the Royal Chronicles of Ayutthaya (Most of the other
versions put its construction at 880 of the Chulasakkarat era or somehow 20 years
earlier). [1]
