Footnotes:
(1) Sub-district called after the village Ban Samphao Lom near the Chao Phraya River. The village is on the Monthon Krung Kao map (1916 CE). John Bowring (1857, London, John W. Parker and Son, West Strand), in his book ‘The Kingdom and People of Siam’, wrote: "Between the modern and the ancient capital, Bangkok and Ayuthia, is a village called the “Sunken Ship,” the houses being erected round a mast which towers above the surface at low water."
(2) Khu Cham, or the Cham Moat, is an existent canal situated off the city island in the southern area of Ayutthaya, running through the Samphao Lom and Khlong Takhian sub-districts. The canal splits off from the present Chao Phraya River about 500 meters east of Wat Phutthaisawan and runs south to join Khlong Takhian, nearly at the latter’s confluence with the Chao Phraya River.
(3) The Pak Khlong Khu Cham floating market was one of the four large floating markets on the river around Ayutthaya ("Pak" stands for the mouth of the canal). [1]
(4) A "surau" is a Malay word for a small Muslim prayer hall or house used for daily prayers. It does not have the same status as the "masjid" (Arabic - place of prostration) or mosque, to be used for the special Friday prayers. A surau can be upgraded to a mosque, but a mosque can never be downgraded to a surau, even if the Muslim community builds a new mosque. It can be more or less compared with a chapel and a church for the Christians. The Surau Khaek is mentioned on the 19th-century map.
(5) On visiting the area in August 2009 CE, local people stated that the Muslim cemetery was built upon the ruins of a Buddhist monastery called Wat Thong. Old bricks were scattered all along the graveyard, in fact, a brick mound, which gives some plausibility to the statement of the locals. The indication of Wat Thong in this location on the 1993 CE FAD map is likely based on this information. In this case, the cemetery should date from the post-Ayutthaya period. The Burmese probably used Wat Thong as a war position and was left prior by the Buddhist clergy. The monastery must have been seriously damaged in the siege of Ayutthaya in 1767 CE.
