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) Khlong Wat Phraya Phan is a small defunct canal in the southern area of Ayutthaya, in Samphao Lom Sub-district. Its former existence is disputed as there are no traces of this canal found today. The canal is, however, mentioned on Engelbert Kaempfer's draft map (1690 CE) and published map of 1727 CE. Based on these maps, the origin of the canal was situated between Wat Tha Sak and Wat Yi Kham (Wat Tha Sak can be noticed on Kaempfer's draft map). The waterway split off from the loop in the old Lopburi River (today the Chao Phraya River) just opposite Pratu Khlong Thep Mi. The canal ran towards Wat Phraya Phan, passing along the west side of Wat Phraya Kong. Whether or not the canal ended up in the Khu Cham is unknown. Jumsai mentions the Wat Phraya Phan Canal in his work The Reconstruction of the City Plan of Ayutthaya (1970). [Jumsai, Sumet. The reconstruction of the city plan of Ayutthaya (1970).

(3) Based on the Royal Chronicles of Ayutthaya, King Chakkraphat (reign 1548-1569 CE) established Nakhon Chai Sri by joining some parts of Rat Buri and Suphan Buri (2006, p. 41)
(4) A market in the Samphanthawong District of Bangkok, popularly known as the 'Thieves Market' as formerly mostly stolen goods were sold there.
