WAT SI FAN (วัดสีฟัน)
Wat Si Fan or the Monastery of the Tooth Brushing was located outside the city
island in the northern area of Ayutthaya in Hua Ro Sub-district on the west bank of the
new
Lopburi River.

It was situated just south of the ruin of
Wat Chumphon. There are no traces remaining of
this monastery at ground level. The site has been completely disturbed by ground
elevation.

Its historical background and period of construction are unknown.

The Royal Chronicles of Ayutthaya mention that an impostor named Tham Thian,
formerly an attendant of Prince Aphaithot, the brother of King Narai, rebelled again King
Phetracha (R. 1688-1703) and gained a great number of adherents, by giving him out as
the Prince. The pseudo-prince and his army reached Ayutthaya somewhere in the vicinity
of
Wat Maha Lok and Wat Monthop. His elephant was struck by one of the eight big
guns of the
Maha Chai Fortress. He fell off his elephant and was injured. His followers
panicked and dispersed in disorder. Tham Thian was captured the next morning in the
flower garden of the Monastery of Tooth Brushing and executed. His followers became
reapers of grass for the elephants. [1] [2]

" In 1060 of the Royal Era, a year of the tiger, the end of the decade, His Highness,
the Supreme Holy Lord Child, Prince of the Holy Royal Palace Enclosure of
Excellence went to watch boxing with His holy eyes at the elephant corrals.
Wretched Tham Thian pretended he was Celestial Lord Aphaithot, who had been
taken to be pounded to death at the Monastery of the Carrion, and took the
elephant Auspicious Jeweled Seat, which was at Lopburi, to ride on in. The
retainers who came along with him numbered about five hundred. Of the farmers
harvesting rice [who joined him], some carried spears and some sharpened
shoulder poles. Khun and luang of the Prince of the Holy Royal Palace Enclosure
of Excellence prostrated themselves to tell the Supreme Holy Lord Omnipotent.
The Supreme Holy Lord Omnipotent stated, "If a person possessing merit has
really come already, We will hand over [the royal wealth]." His Highness, the
Prince of the Holy Royal Palace Enclosure was at the Fort of Grand Victory and
Tham Thian halted his elephant at the foot of the embankment. A holy command
was issued sending police to scrutinize his person so as to be sure [he was who he
pretended to be]. The police came back, prostrated themselves and said, "He’s not
Celestial Lord Aphaithot!" Thereupon a holy command was issued to have all
eight of the great guns fired forth simultaneously. The followers of Tham Thian
accordingly were routed during the evening. Early the next morning they were
able to capture the person of Tham Thian in a flower garden of the Monastery of
Tooth Brushing and he was taken away and put to death. His entire following was
taken to become reapers [of grass for the elephants]."

The inhabitants of many districts near Nakhon Nayok, Lopburi and Saraburi, who had
been implicated in the rebellion, fled their homes for fear of punishment, so that part of
the country was almost depopulated. According to Burmese history, these fugitives
settled in Burma. [3] Some sources put this event in 1690 others in 1696 or 1698.

The monastery is indicated on 1974, 1993 and 2007 Fine Arts Department (FAD)
maps. The temple was once situated in geographical coordinates: 14° 22' 27.50" N,
100° 34' 22.83" E.
