Footnotes:
(1) The name of the temple is presently written as พุทไธศวรรย์ of which พุทไธ and ศวรรย์, I could not find a translation or meaning. I presume that the word should be written as พุทธ (Buddha) and ไอศวรรย์ (kingship) - พุทธไอศวรรย์ or Buddhist Kingship. Richard Cushman, in the Royal Chronicles of Ayutthaya, translated Wat Phutthaisawan as ‘Monastery of the Sovereignty of the Buddha.’ มไหศวรรย์ (Mahai Sawan) meaning supremacy, great wealth, great power, great might, greatness or sovereignty.
(2) Ban Samphao Lom was situated near the Chao Phraya River in the Samphao Lom Sub-district. 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."
(3) Not many people realise the Chao Phraya River was not running on the west side of the city island in the Ayutthaya period. At that time, it was the Lopburi River that flowed around Ayutthaya. Today's Chao Phraya River ran through the Bang Ban Canal to Si Kuk and from there to Bang Sai (historical site: Chedi Wat Sanam Chai), where the Lopburi River joined the Chao Phraya River. At the time, the Chao Phraya River was situated about ten kilometres west of the centre of Ayutthaya. The city was linked to the ancient Chao Phraya River in the northwest of Ayutthaya via the Khlong Maha Phram and in the southwest via the Khlong Nam Ya. Steve Van Beeck (1994), in 'The Chao Phya: River in Transition" (Oxford University Press - New York.), writes that "It was not until 1857 that an alternative path was created [for the Chao Phraya River]. A 5-kilometre channel was dug from the entrance of Wat Chulamani to Ban Mai. The river responded by following this new course and abandoning the old one, in effect making a secondary river of the stretch that ran from Ban Mai, and into the Chao Phya Noi. Half as wide as the river above and below it, the 1857 Ban Mai shunt funnels the Chao Phya down to Ayutthaya."
(4) Khlong Takhian is a still existing canal south of Ayutthaya's city island, running mainly through Pak Kran and Khlong Takhian sub-districts. The canal is named after the Malabar Ironwood, a tree often used for making boats and ship masts. The canal originates at the Chao Phraya River near the St Joseph Church in the former Cochin Chinese Settlement. It has its mouth further south, back in the Chao Phraya River, below the former Portuguese settlement, and opposite the northern tip of Rian Island (Ko Rian). The canal was a man-made shortcut or 'Khlong lat' between two stretches of the old Lopburi River at a time the waterway was surrounding Ayutthaya, used by boats to avoid the heavy current of the river and the turbulent waters near the Bang Kraja confluence. Takhian originates from the former village called Ban Tha Khia near the mouth of the canal.
(5) Khlong Chakrai Yai is part of a waterway running through the west of Ayutthaya from north to south. The canal was the extension of Khlong Pak Tho and ran from the Lam Hoei Bridge to the Chakrai Yai Gate opposite Wat Phutthaisawan. The canal was a shortcut through the oxbow of the Lopburi River and connected the old Lopburi River, presently Khlong Mueang, in the north with - what is today - the Chao Phraya River in the south. Ban Chakrai was a village on the city island but outside the city walls.
(6) Khu Cham, or the Cham Ditch, 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 metres east of Wat Phutthaisawan and runs south to join Khlong Takhian, nearly at the latter’s confluence with the Chao Phraya River.
(7) The Luang Prasoet Chronicle of Ayudhya (Phraratchaphongsawadan Krung Si Ayudhya chabap Luang Prasoet) is the oldest chronicle in the Thai language discovered until today. The chronicle was written in 1680 CE by order of King Narai. The chronicle deals with the events in Ayutthaya between 1324 and 1604 CE in a very abridged way. The text was discovered in Phetchaburi by Luang Prasoet in 1907 CE and came to bear his name. With the probable exception of this chronicle, all other versions of the Chronicles of Ayutthaya were written in the Bangkok period after the fall of Ayutthaya. “May it be of good omen! In 1042, a year of the monkey, on Wednesday, the twelfth day of the waxing moon of the fifth month, the King [Narai] was pleased to order, “Get out the chronicles of events recorded by the royal astrologers of earlier times and the chronicles of events to be found in the Hall of the Archives cull out the events to be found in these royal chronicles and collate them together in one place in chronological order up to the present.”
(8) There is a mystery around the finding of this image. Amatyakul sets the discovery in the reign of Rama I. An information board on the site of Wat Phutthaisawan gives 1784 CE as the year of the discovery, and both sources refer to Krom Luang Thepphonphak as the one who made the discovery. The problem here is that this Prince was only born in 1785 CE and became director of the Royal Elephant Department in the reign of Rama II (1809-1824 CE), as thus after the death of Rama I. (Ref: Tri Amatyakul (1957). Guide to Ayudhya and Bang-Pa-In. pp. 60-1). Chris Baker in “The Grand Palace in the Description of Ayutthaya,” writes that the image was placed by King Taksin (reign 1767-1782 CE) in Wat Suwannaram at Thon Buri. King Rama, I decided to revive the water oath ceremony and brought the image to Bangkok to preside at the ceremony and built Phra Thep-bidon Hall inside the palace for the purpose.
